3. 7670 TN OVERVIEW

Warning: This section is UA release independent and for information ONLY.

3.1. UMTS NETWORK OVERVIEW

Alcatel-Lucent take advantage of transport nodes (often referred to as Point of Concentration nodes) to provide additional features and functionality, not supported natively on the RNC. The following two Alcatel-Lucent products have been identified:

· The Alcatel-Lucent 7670 Routing Switch Platform (RSP). This product is proposed to replace the Nortel PP 15K POC.

· The Alcatel-Lucent 7670 Edge Service Extender (ESE). This product is proposed to replace the Nortel PP 7K POC.

This is the support of the Alcatel-Lucent 7670 ESE & RSP transport nodes to interoperate with the RNC 1500 of the Alcatel-Lucent UTRAN portfolio in UA05. Initially only interoperability is requested with no W-NMS integration.

4. 7670 RSP DESCRIPTION

4.1. 7670 RSP OVERALL HARDWARE DESCRIPTION

4.1.1 7670 RSP NETWORK ELEMENT AND NODES

The 7670 RSP is a carrier-grade multi-service IP platform enabling service providers to offer L2 and L3 services in their native mode.

The 7670 RSP Transport Node provides high density ATM/IMA termination, ATM VP/VC switching, and advanced VP shaping features required at the RNC location.

Figure 4.1-1: 7670 RSP Transport Node – OC3/STM1 on Iub/Iu

Note : Those cards, ESC, MR16 and MR48 are presented in next chapter.




4.1.2 7670 RSP SINGLE SHELF DESCRIPTION

The 7670 RSP is a single-shelf platform that is front mounted in an industry-standard 23in. rack, supporting a switching capacity of 50 Gb/s bi-directional.

Figure 4.1-2: 7670 RSP Single Shelf

The 7670 RSP single shelf system has a mid-plane design in which field-replaceable cards are inserted in the front and rear of the shelf. For each line card you install, an I/O card is required in the rear of the shelf, as illustrated in the below figure.

Note: All cabling is located at the rear of the shelf.

Figure 4.1-3: 7670 RSP Midplane Design

The 7670 RSP contains system, line and I/O cards. System cards control and manage the switch. Line cards process L2/L3 network traffic. I/O cards provide the interface between the network and the line cards.




4.1.3 7670 RSP LOCATION AND ENVIRONMENTAL SPECIFICATION

You must install the system in an equipment rack or cabinet located indoors, in a dry, clean, well-ventilated and well-illuminated area. The system accommodates cabling for either raised-floor or overhead cable rack environments.

Table 4.1-1: 7670 RSP Site specification

4.1.4 7670 RSP SHELF SPECIFICATION

The RSP 7670 shelf must be installed in a 23 in cabinet. Do not install a 7670 RSP shelf in a closed cabinet, regardless of system or shelf configuration; otherwise, thermal shutdown and/or failure may result. Alcatel’s closed cabinet design (2200 mm × 900 mm × 750 mm ETSI footprint) with custom cooling vents is the only exception to this rule. For seismic installations, we recommend installation of a 7670 RSP shelf in an Alcatel 23 in, 7 ft Zone 4 seismic rack with a custom airflow base (44 RU).

All 7670 RSP shelves are 600 mm deep, including fiber management.

Note (1) : Peripheral shelf is the standard shelf use in single shelf configuration. There is a shelf called Switching shelf for multi-shelf configuration, it is not presented here. For more details see [Ext_NTP_002]

Figure 4.1-4: 7670 RSP shelf specification

4.2. 7670 RSP SYSTEM ARCHITECTURE

4.2.1 SYSTEM ARCHITECTURE DESCRIPTION

The 7670 RSP is a standards-based platform designed for use in the backbone of the next-generation network. You can use the 7670 RSP in a single-shelf architecture or multi-shelf architecture. The multi-shelf architecture consists of a control shelf, Switching shelves, and Peripheral shelves.

The 7670 RSP contains system cards, line cards and I/O cards. System cards control and manage the switch. Line cards process network traffic. I/O cards provide the interface between the network and the line cards. The 7670 RSP provides 56.32 Gbps switching capacity, it can support up to 14 Universal Card Slot (UCS) cards per shelf and each slot has a capacity: up to OC48c (approx. 3.52G per slot including overhead)




NETWORK MANAGEMENT

The 7670 RSP can be managed through SNMP, the CLI, and through the industry-leading 5620 Network Manager. With the 5620 Network Manager, the 7670 RSP inherits the power of a suite of applications for end-to-end connection management, network data collection, and service management.

REDUNDANCY

All switch components are fully redundant, including control, fabric, power, cooling, management interfaces, and line interfaces. Each redundant component can be replaced without any impact to service.

TRAFFIC MANAGEMENT

The 7670 RSP employs rigorous traffic management processes to ensure maximum switch efficiency and bandwidth use. All ATM service categories are supported by the following traffic management features:

• per-VC queueing and scheduling using WFQ

• per-VC shaping for all service categories

• VPA Shaping

• intelligent buffer management with frame discard

• explicit rate and VS/VD support for ABR

• Supports 500K P2P (PVCs+SVCs+ SPVCs) connections

• Supports 800 P2MP root endpoints per system

• Supports 3000 calls/sec sustained per node

• 8 User service categories CBR,rtVBR1,2, nrtVBR1,2,3, ABR and UBR

IP FUNCTIONALITY

The 7670 RSP has IP functionality, including:

• IP forwarding

• IP routing

• MPLS

• Layer 3 VPNs (RFC 4364, formerly known as RFC 2547)

• Layer 2 VPNs

• IP multicast

• IP version 6 (IPv6)




Figure 4.2-1: 7670 RSP system architecture

4.2.2 SWITCHING ELEMENT

The heart of the system is based on two switching cards (If only one present, alarms are raised). These switch cards are connected to all line cards by point-to-point lines. Main characteristics are :

• 56.32 Gbps of aggregate bandwidth

• 3.52Gbps of bandwidth to all 14 line card slots

• 3.52Gbps of bandwidth to both control cards slots

• Non-blocking, self-routing single stage switch core

4.2.3 SYSTEM SYNCHRONISATION UNIT (SSU)

The SSU is a clocking module installed on the control card. It receives timing signals from either external reference sources connected to ports A or B of the Facilities Card (FAC) or from a port on any of the line cards.

The SSU uses the timing signals to provide the following synchronization and timing functions:

• synchronisation of all interface cards to common timing source

• software-controlled selection and prioritization of timing sources

• stratum 3 holdover capability, if the timing sources become faulty

• free run to stratum 3 tolerances, if the SSU cannot enter holdover mode

The SSU can use six synchronization sources numbered 1 – 6 in decreasing order of priority:

• sources 1 – 4 can derive timing from either the external A or B ports of the FAC card, or any optical port on any interface card

• source 5 corresponds to the holdover mode

• source 6 corresponds to free-run

SSU OPERATION

• The SSU locks to source number 1, if possible.

• If a source is faulty, it locks to the next source number until it reaches 5. (holdover)

• If there is no holdover value, it locks to source number 6.

The SSU can operate in two modes: revertive and non-revertive.

In non-revertive mode:

• If a higher priority source becomes available while the SSU-2 is locked to sources 2, 3 or 4, it remains on the lower priority source.

• If a higher priority source becomes available while the SSU-2 is locked to 5 or 6, it locks to the higher priority source.

In revertive mode:

• If a higher priority source becomes available while the SSU-2 is locked to a lower priority source it reverts to the higher priority source.




4.2.4 REDUNDANCY SWITCH FABRIC

Switching fabric redundancy ensures that traffic between line cards is uninterrupted if a fabric failure occurs. The line card transmits the incoming data to both Fabric X and Fabric Y. The line card only accepts outgoing traffic from the active switching fabric. The same error checks, diagnostics, monitoring, and statistics are performed on both the active and inactive fabric.

Figure 4.2-3: 7670 RSP switching fabric redundancy application

OPTION 2 – LINE PROTECTION (I/O CARD REDUNDANCY ONL Y)

This option provides 1+1 hot redundancy at the I/O level and 1+1 APS port protection.

Figure 4.3-4: 7670 RSP Line Protection

Rule: 7670 RSP – Redundancy I/O card (HC)

Only two I/O cards in adjacent slots of the same type can be used for line card redundancy.

APS configuration can be configured only between associated port, this means same port number of two adjacent cards

For card location please refer to rule here after: Card positioning for redundancy

Rule 4.3-3: 7670 RSP- Redundancy I/O card

As there are two location for I/O card in a slot, the APS redundancy is on half slot based. See example :

Figure 4.3-5: 7670 RSP I/O Protection example

In that case, APS is setup between STM4 ports but there is no APS protection for The OC3 ports

4.3.4 I/O CARDS

The I/O cards are inserted in half-height slots located in the rear of the shelf, behind each line card. Depending on the type of line card installed, and the desired number of I/O ports required, one or two I/O cards will be required.

Figure 4.3-7: 7670 RSP shelf I/O slots side

Only part of the global offer is presented here. Those are the main cards that will be used for UMTS project. For other cards with higher capacity please refer to [EXT_NTP_002].

The 7670 RSP supports optical OCn and STMn I/O cards with the following ranges:

• SR

These cards are designed for short-reach applications using 62.5/125 µm (core/cladding diameter) optic cables less than 2 km (1.3 mi) in length (for OC3/STM1 I/O cards) or less than 500 m (0.3 mi) (for OC12/STM4 and OC48/STM16 I/O cards). Most SR cards use MMF cables because they are based on LED optical technology. The only SR card that uses SMF cables is the 1-port OC48c/STM16 ATM I/O card.

• IR

These cards are designed for intermediate-reach applications using optic cables up to 15 km (9.32 mi) in length. All IR cards use SMF cables because they use laser optical technology.




• LR

These cards are designed for long-reach applications using optic cables up to 40 km (24.85 mi) in length. All LR cards use SMF cables because they use laser optical technology.

• XLR

These cards are designed for extra long-reach applications using optic cables up to 110 km (68.35 mi) in length. All XLR cards use SMF cables because they use laser optical technology.

8-PORT OC3C/STM1 I/O CARD

The 8-port OC3c/STM1 I/O card terminates eight physical OC3/STM1 interfaces. You can associate up to two 8-port OC3c/STM1 I/O cards with one Multi-Rate 16 ATM line card.

The 8-port OC3c/STM1 I/O card types are:

• SR

• IR

• LR

• XLR

The system maintains connections when you replace an I/O card with a card of a different range. If you do this, the lasers are turned off until you change the configured card type to match the installed card type. For example, you can replace an 8-port OC3c/STM1 IR card with an 8-port OC3c/STM1 LR card without affecting connections.

You connect the ports with SC-duplex connectors.

8-PORT OC3/STM1 I/O CARD

For use with the MR48 and ESC line cards, the 8-port OC3/STM1 I/O card terminates eight physical OC3/STM1 optical interfaces. The I/O card terminates both ATM (cell relay) and IP/POS (PPP) protocol channels. On the ESC, only cell relay protocol channels are supported. Each port on the I/O card can terminate one channel at the OC3/STM1 data rate of 155.52 Mb/s. For the ESC, each OC3/STM1 port supports up to 84 DS1 or 63 E1 channels.

There are three types of the 8-port OC3/STM1 I/O card:

• SR

• IR

• LR




One MR48 line card supports two 8-port OC3/STM1 I/O cards. One ESC supports one 8-port OC3/STM1 I/O card.

You connect the ports with LC-duplex connectors.

8-PORT STM1 ELECTRICAL I/O CARD

The 8-port STM1 Electrical I/O card has eight electrical interfaces. Each interface has two coaxial cables: one for transmitting signals and one for receiving signals. This card can only be used with the Multi-Rate 16 ATM line card. You connect the ports with SMZ connectors.

Caution — The I/O cables for the 8-port STM1 Electrical I/O card must be double-shielded coaxial cable to maintain EMC compliance to Class B.

8-PORT STM1 ELECTRICAL MR48 I/O CARD

The 8-port STM1 Electrical MR48 I/O card terminates eight physical STM1 electrical interfaces. This card can only be used with the MR48 and ESC line cards. One MR48 line card supports two 8-port STM1 Electrical MR48 I/O cards. One ESC line card supports one 8-port STM1 Electrical MR48 I/O card.

The electrical interface on this card provides 155 520 kb/s data rates over two coaxial cables (one for transmitting signals and one for receiving signals). All eight interfaces on the I/O card are the same type.

You connect the ports with SMZ connectors.

Caution — The I/O cables for the 8-port STM1 Electrical MR48 I/O card must be double-shielded coaxial cable to maintain EMC compliance to Class B.

4-PORT OC12/STM4 CHANNELIZED I/O CARD

For use with the channelized MR48 and ESC line cards, the 4-port OC12/STM4 Channelized I/O card terminates four physical OC12/STM4 interfaces. The OC12/STM4 interfaces on the I/O card transmit and receive optical SONET signals at a full 622 Mb/s. This speed is an aggregation, with the total sum being the OC12/STM4 rate

When used with the MR48 line card, the 4-port OC12/STM4 Channelized I/O card supports both ATM (cell relay) and IP/POS (PPP) protocol channels. When used with the ESC, the 4-port OC12/STM4 Channelized I/O card supports ATM (cell relay) and UDT protocol channels.

There are three types of the 4-port OC12/STM4 Channelized I/O card:

• SR

• IR

• LR




Each of the MR48 and ESC line cards support one 4-port OC12/STM4 Channelized I/O card.

You connect the ports with SC-duplex connectors.

Rule: 7670 RSP –OC12/STM4 I/O Card capacity restric tion (M)

All four ports are available for use on the MR48 line card. Only ports 1 and 2 are available for use on the ESC. The ESC disables the lasers and LEDs for ports 3 and 4.

You can install the 4-port OC12/STM4 Channelized I/O card in I/O slot 1 only. The I/O card can be physically placed in I/O slot 2, but you cannot configure the card in that slot.

5. 7670 ESE TN DESCRIPTION

5.1. 7670 ESE OVERALL HARDWARE DESCRIPTION

5.1.1 7670 ESE NETWORK ELEMENT AND NODES

The 7670 ESE provides low-speed multi-service adaptation, aggregation, and switching, supporting the reliable, cost-effective delivery of IP, Ethernet, frame relay, ATM, and circuit emulation services. The 7670 ESE was firstly designed as an extension of the RSP to provide edge connectivity, so the name ESE : Edge Services Extender. The first name was 7670 RSP ESE, but now the RSP was removed as the ESE is not only an extension.

The 7670 ESE Transport Node provides high density ATM/IMA termination, and ATM VP/VC switching capabilties required at the RNC location.

The 7670 ESE Transport Node supports two configurations.

The first configuration allows connecting up to 320 protected T1/E1 ATM/IMA ports on the Iub.

• Maximum configuration: up to 320 T1/E1 ATM/IMA ports for Iub; increments of 32, 64, 96 ... 320.

5.1.2 SINGLE SHELF HW DESCRIPTION

The 7670 ESE is a single-shelf platform that can be front or mid-mounted in an industry-standard 19-in. or 23-in. rack, supporting a switching capacity of 3.2 Gb/s bi-directional.

Figure 5.1-3: 7670 ESE Single Shelf

The 7670 ESE single shelf system has a backplane design in which field-replaceable cards are inserted in the front of the shelf.

The 7670 ESE shelf encloses the control complex, interface cards, and backplane.

The 7670 ESE shelf has 14 slots and accommodates two card sizes.

• Full-height cards are 50.8 cm (20 in.) high.

• Non-full-height cards are 30.5 cm (12 in.) high and are adapted to full height with adapter cards.

The ECC cards use the first and last slots, labelled ESE CC X and ESE CC Y.

The interface cards use the other 12 slots, labelled 1 to 12. Most interface cards require a distribution panel or MAU to connect to the system.

The backplane provides the connectors for the 7670 ESE cards.

Empty slots in the card file must be fitted with a filler plate to minimize EMI emissions and optimize system cooling.

1:N SPARING BUS

The 7670 ESE has an integrated 1:N sparing bus that allows for 1:N redundancy of interfaces without any shelf changes or external hardware for T1/E1 and DS3 interfaces. External protection panels are required for 1:N protection of OC3/STM1 Multi-service card interfaces.




1:N line card redundancy uses one protection card for up to five working cards.

The cards and adapter cards form a protection group. A protection card assumes active operation if a working card fails. All connection information and configuration settings are copied to the protection card when the switch occurs.

The following rules apply to protection groups.

• All OC3/STM1 Multi-service with CR/IMA cards in a protection group must be on the same fabric port, either fabric port 1, 2 or 5 of the ECC switching fabric sub card.

• All 32-port T1/E1 Multi-service with CR/IMA cards in a protection group must be on the same fabric port, either fabric port 1, or 2 of the ECC switching fabric subcard. Fabric Port 5 may not be used by the 32-port T1/E1 Multi-service card with CR/IMA.

• A working card can belong to only one protection group.

• All cards in the group must be of the same type.

• All cards in a protection group must be in adjacent slots, with the protection card in the lowest numbered slot.

• A protection group may not span the slot 6-slot 7 boundary.

You can configure up to six protection groups on a shelf. All configuration settings and connections are configured on the working card, even if the protection card is active. 1:N line card redundancy provides protection against card failures, but not against failed transmission facilities.

POWER

The power module unit consists of two replaceable power modules that accept dual –48 V DC power feeds and power returns through the terminal block, located on the back of the shelf.

COOLING UNIT

The cooling unit provides forced-air cooling to the 7670 ESE shelf.

The cooling unit consists of a fan control board and a tray containing three fans.

The fan control board automatically controls the speed of the fans by detecting changes in the internal air temperature. The ECC card detects when a fan is removed.

The cooling unit can be removed and replaced without interrupting power to the shelf.

EMI COVERS

The back of the 7670 ESE shelf provides two rows of twelve 64-pin telco connectors, which are used for MAUs (Media ATTACHMENT Unit) and cables to attach to external




devices. The shelf is shipped with 12 EMI covers on the bottom row of connectors. These covers are removed when connections are made and can be reused on an unused connector or stored for future use.

ALARM CARD

The Alarm card provides visual alarm indications for critical, major, and minor alarms occurring on the shelf. The card also has an ACO/LT switch.

5.1.3 7670 ESE SITE SPECIFICATION

The shelf must be located in a dry, environmentally controlled building or enclosure. Although the shelf has been designed and tested to relevant standards of conducted electromagnetic interference, it may be affected by strong sources of electromagnetic radiation in the near field, such as elevators, air conditioners, photocopiers, and facsimile machines.

The location must accommodate the planned type of installation, including interfaces, terminals, modems, NTIs, and cabling. When mounted in a rack, the shelf requires a 19- or 23-in. rack that is properly installed and stable (for example, bolted securely to the floor) and grounded. A minimum of 1 m (3 ft) of space should be provided in front of and behind the rack.

(2) Pollution Degree as defined in IEC 60950-1




5.1.4 7670 ESE POWER SUPPLY AND CONSUMPTION

DC POWER DISTRIBUTION

The dc power distribution provides a maximum of 2100 W, distributing 140 W per slot (1960 W) for the 14 slots, 125 W for the cooling unit, and 15 W for the Alarm card. For detailed info refer to Appendixes A of [Ext_NTP_001]

INPUT VOLTAGE RANGE

All dc voltage levels are defined at the demarcation point (the input power terminal block), which is the point between the customer-supplied power and the 7670 ESE shelf. The shelf normally operates over the input power range of –40 to –75 V dc. The shelf will not be damaged or cause any internal over current protection devices to operate if voltages in the range of 0 to –40 V dc are applied for any duration. When normal input voltage is restored, the shelf recovers automatically.

5.2. 7670 ESE SYSTEM ARCHITECTURE

5.2.1 ARCHITECTURE

The 7670 ESE uses interface cards to connect to transmission equipment and user devices. There are two types of interface cards: service adaptation cards and cell relay cards. Service adaptation cards provide non-cell relay transport and adapt non-cell relay traffic into cell relay traffic; cell relay cards provide cell relay transport.

Most interface cards require a distribution panel or MAU to connect to the system.

The 7670 ESE is designed for high switching capacity and redundancy. It achieves 99.999% switch availability, fulfilling service-level agreements with true carrier-grade reliability.




Figure 5.2-1: 7670 ESE System architecture

Note : P1-1, P1-X/F, P1-8 , see Endpoint Identifier Chapter below for detailed explanation.

5.2.2 NETWORK MANAGEMENT

The 7670 ES can be managed through SNMP, the CLI, and through the industry-leading 5620 Network Manager. With the 5620 Network Manager, the 7670 ESE inherits the power of a suite of applications for end-to-end connection management, network data collection, and service management.

5.2.3 REDUNDANCY

All switch components are fully redundant, including control, fabric, power, cooling, management interfaces, and line interfaces. Each redundant component can be replaced without any impact to service.

5.2.4 TRAFFIC MANAGEMENT

The 7670 ESE employs rigorous traffic management processes to ensure maximum switch efficiency and bandwidth use. All ATM service categories are supported by the following traffic management features:

• per-VC queueing and scheduling using WFQ

• per-VC shaping for all service categories

• VPA Shaping

• 8 User service categories CBR,rtVBR1,2, nrtVBR1,2,3, ABR and UBR

Furthermore as the ESE was designed as an extension of the RSP, it mainly supports same kind of traffic services as the RSP.




5.2.5 SYSTEM SYNCHRONISATION UNIT (SSU)

The SSU is a clocking module installed on the ECC card. It receives timing signals from either external reference sources connected to ports A or B of the ECCI Card or from a port on any of the line cards.

The SSU uses the timing signals to provide the following synchronization and timing functions:

• synchronization of all interface cards to common timing source

• software-controlled selection and prioritization of timing sources

• stratum 3 holdover capability, if the timing sources become faulty

• free run to stratum 3 tolerances, if the SSU cannot enter holdover mode

The SSU can use six synchronization sources numbered 1 – 6 in decreasing order of priority:

• sources 1 – 4 can derive timing from either the external A or B ports of the FAC card, or any optical port on any interface card

• source 5 corresponds to the holdover mode

• source 6 corresponds to free-run

SSU OPERATION

• The SSU locks to source number 1, if possible.

• If a source is faulty, it locks to the next source number until it reaches 5. (holdover)

• If there is no holdover value, it locks to source number 6.

The SSU can operate in two modes: revertive and non-revertive.

In non-revertive mode:

• If a higher priority source becomes available while the SSU-2 is locked to sources 2, 3 or 4, it remains on the lower priority source.

• If a higher priority source becomes available while the SSU-2 is locked to 5 or 6, it locks to the higher priority source.

In revertive mode:

• If a higher priority source becomes available while the SSU-2 is locked to a lower priority source it reverts to the higher priority source.




Rule: 7670 ESE – Synchronization port selection (R)

It is strongly recommended to use the OC3/STM1 port connected to the RNC for Iub as synchronization source. As APS is configured use the two ports to secure the synchronization.

Rule 5.2-1: 7670 ESE Synchronization port selection

5.3. 7670 ESE MODULES

5.3.1 SYSTEM CARDS

The following 7670 ESE system cards provide management and switching capability within the single-shelf system:

• ESE Control Card (ECC) equipped with OC3/STM1 Line Module

• ESE Control Complex Interconnect Card (ECCI)

ESE CONTROL CARD

The ECC system card performs the switching, call processing, and control functions for the 7670 ESE. In a redundant system, two ECC cards are required. Optionally, you can order the ECC card with a single-port OC12/STM4 line module or a 4-port OC3/STM1 line module to provide cell relay service from the 7670 ESE to the network.

OC3/STM1 LINE MODULE

The OC3/STM1 line module is a 4-port UNI/NNI module that, if ordered, comes preinstalled on the ECC card.

The module can be configured as OC3 or STM1, but not both simultaneously. All four ports on this line module are completely independent and can be used to make point-to-point or point-to-multipoint connections between the 7670 ESE shelf and multiple points in a network. The OC3/STM1 line module is available in short, intermediate, or long laser-reach variants.

Two (2) ECC cards are required, with two (2) OC3/STM1 line modules.

Rule: 7670 ESE – OC3/STM1 Line Module for RNC conne ction (R)

This line Module is strongly recommended to give RNC side connectivity.

APS 1+1 will be activated through those two line module.

Rule 5.3-1: 7670 ESE- OC3/STM1 Line Module for RNC connection




REDUNDANCY

For 4-port OC3/STM1 line modules, 1+1 APS redundancy is set automatically when a second ECC card equipped with the same type of line module (independent of the reach type) is installed and configured in the shelf. This second card becomes the protection card. For 4-port OC3/STM1 line modules, each card protection group automatically creates a port protection group for each pair of ports. Each port protection group can independently perform activity switches. You can configure APS and perform APS maintenance functions on a port protection group or card protection group. Performing APS maintenance on a card protection group applies the function to all ports on that card.

Rule: 7670 ESE – Dual Homing feature (R)

This feature, implemented from 5.1 release, allows to use all the 8 ports (4 ports by ECC) independently. This means that ECC X can control ports on the ECC Y.

Note that the APS is switched off by default when d ual homing is activated. You have to choose between APS or (exclusive) Dual Homi ng.

Rule 5.3-2: 7670 ESE- Dual Homing feature

ESE CONTROL COMPLEX INTERCONNECT (ECCI)

The ECCI provides BITS inputs/outputs. It’s connected to the back of the 7670 ESE shelf. No cables are required.

There are two variants of the ECCI:

• North America ECCI, with 1.544-MHz (standard T1) BITS clock inputs

• International ECCI, with 2.048-MHz (standard E1) external clock inputs and outputs

Figure 5.3-2: 7670 ESE International ECCI




5.3.2 LINE CARDS

32 PORT T1/E1 MS CARD

The 32-port T1/E1 MS card connects to T1 or E1 interfaces. Using configuration management, you can switch the card between T1 mode and E1 mode. The card uses AAL-1 to transport unstructured T1 or E1 circuits and n × 64-kb/s channels across an ATM network. Structured or unstructured service can be configured per port.

A T1/E1 adapter card provides electrical interfaces for a 100-Ω T1, 120-Ω E1, or 75-Ω E1 interface.

The multi-service capabilities of the card are provided by an optional, add-on CR/IMA module. The CR/IMA module supports IMA protocol version 1.0, which complies with ATM Forum AF-PHY-0086-000 requirements, and IMA protocol version 1.1, which complies with ATM Forum AF-PHY-0086.001 requirements.

This module can support IMA versions 1.0 and 1.1 simultaneously on a per-port basis. For interoperability, the far-end equipment connected to the T1/E1 MS card must support the same standards-compliant IMA protocol as the near-end card.

Figure 5.3-3: 7670 ESE – 32Port T1/E1 Multi Service Card

REDUNDANCY

The 32-port T1/E1 MS card supports 1:N line card redundancy, in which up to five working cards of the same type form a protection group with one protection card.

If you configure 1:N line card redundancy for a 32-port T1/E1 MS card, you can remove the interface card, but you must leave the adapter card in the shelf for protection to continue.




Rule: 7670 ESE – Group protection 32Port T1/E1 MS Card(HC)

There are two protection groups in the ESE shelf, Group 1 for slots 1 to 6 and Group 2 for slots 7 to 12 . When protection is activated slot 1 for Group 1 and slot 7 for Group 2 is reserved for the protection card, this means that no I/O port will be useable/needed in for these two slots. Group Protection can be activated separately.

Rule 5.3-3: 7670 ESE- Group Protection 32 Port T1/E1 MS Card

CR/IMA MODULE

An optional CR/IMA module for the T1/E1 MS card supports any-service-any-circuit deployments. The CR/IMA module provides T1 and E1 cell relay and IMA group services through the T1/E1 MS card.

The CR/IMA module for the T1/E1 MS card lets service providers use T1 or E1 lines for connections with bandwidth that exceeds the T1 or E1 rate. The module supports up to 16 IMA groups.

With its CR/IMA module installed, the T1/E1 MS card transports cell relay or IMA cells within DS1 or E1 circuits.

IMA groups provide scalable bandwidth. The bandwidth of a group is a multiple of the number of links in that group. For example, an IMA group with four T1 links has a bandwidth of 4 × 1.544 Mb/s. You can increase cell stream bandwidth beyond T1 and E1 rates up to a maximum of 8 × T1 or 8 × E1 rates.

Example of a module added to the 32-port T1/E1 MS Card :

Figure 5.3-4: 7670 ESE CR/IMA module added to 32Port T1/E1 Card




DISTRIBUTION PANEL

A variety of distribution panels provide interfaces to connect external equipment to T1 and E1 interface cards on the 7670 ESE. Three distribution panel type are supported for this card; the most common to use on site is the 16-port RJ-45 distribution panel:

• 16-port RJ-45 T1/E1 distribution panel : This support 120 Ω E1 and 100 Ω T1

• 8-port BNC coaxial E1 distribution panel This support 75 Ω E1.

• 32-port SMZ (Type 43) distribution panel : This support 75 Ω E1.

Example of a Distribution Panel. For more details see chapter 5 of [Ext_NTP_001].

Figure 5.3-5: 7670 ESE 16 Port RJ45 T1/E1 distributuion panel

To connect the distribution panel to the 32 Port T1/E1 MS card, a specific cable “Champ to Dual DB-78 Y cable” need to be provided per distribution panel.

Rule: 7670 ESE – Distribution panel for E1/T1 (R)

It is strongly recommended to use the E1/T1 distribution panel to use installation of the E1/T1 connectivity.

Rule 5.3-4: 7670 ESE distribution panel for E1/T1

1 PORT OC3/STM1 MS CARD

The 1-Port STM1/OC3 MS card is a single-port, full-height circuit emulation card that can be configured to support SONET or SDH connections.

For circuit emulation service, the STM1/OC3 MS card transports n × 64 kb/s channels within structured DS1 or E1 circuits, unstructured DS1 or E1 circuits, or unstructured DS3 circuits across an ATM network that uses AAL-1.

There are four variants of the STM1/OC3 MS card. The three optical variants (SR, IR, and LR, for short, intermediate, and long reaches, respectively) support either OC3 or STM1. The electrical variant supports STM1 only.




The multi-service capabilities of the card are provided by an add-on CR/IMA module..

REDUNDANCY

The 1 Port STM1/OC3 MS card, with or without a CR/IMA module installed and configured, supports 1:N redundancy.

1:N line card redundancy uses one protection card for up to five working cards. The cards and adapter cards form a protection group. A protection card assumes active operation if a working card fails. All connection information and configuration settings are copied to the protection card when the switch occurs.

The following rules apply to protection groups.

• All cards in a protection group must be on the same fabric port,

• A working card can belong to only one protection group.

• All cards in the group must be of the same type.

• All cards in a protection group must be in adjacent slots, with the protection card in the lowest numbered slot.

This 1:N redundancy will require to add the protection panel described below.

Rule: 7670 ESE – Group protection 1 Port OC3/STM1 MS Card(HC)

There are two protection groups in the ESE shelf, Group 1 for slots 1 to 6 and Group 2 for slots 7 to 12 . When protection is activated slot 1 for Group 1 and slot 7 for Group 2 is reserved for the protection card, this means that no I/O port will be useable/needed in for these two slots. Group Protection can be activated separately. A protection panel is mandatory to activate this feature

Rule 5.3-5: 7670 ESE- Group Protection 1 Port OC3/STM1 MS Card

The 1 Port STM1/OC3 MS card, with or without a CR/IMA module installed and configured, supports also 1+1 APS redundancy.

Rule: 7670 ESE – APS 1+1 for 1 Port OC3/STM1 MS Car d(HC)

In order to active the APS 1+1 protection, you need to have two identical cards in adjacent slots.

Unidirectional switching mode cannot be configured for STM1/OC3 MS cards with CR/IMA modules when an IMA group is configured on the card. When STM1/OC3 MS cards with CR/IMA modules are configured for 1+1 APS redundancy with an IMA group, they always operate in bidirectional switching mode.

Rule 5.3-6: 7670 ESE- APS 1+1 for 1 Port OC3/STM1 MS Card




CR/IMA MODULE

An optional CR/IMA module for the STM1/OC3 MS card supports any-service-any-circuit deployments. The CR/IMA module provides T1 and E1 cell relay and IMA group services through the STM1/OC3 MS card.

The CR/IMA module for the STM1/OC3 MS card lets service providers use T1 or E1 lines for connections with bandwidth that exceeds the T1 or E1 rate. The module supports up to 42 IMA groups. The system multiplexes the cell streams from each logical port (a T1 or E1 mapped from an STM1 or OC3 circuit) into an IMA group to create a unified cell stream.

With its CR/IMA module installed, the STM1/OC3 MS card transports cell relay or IMA cells within DS1 or E1 circuits with a total aggregate bandwidth of up to 155.52 Mb/s.

IMA groups provide scalable bandwidth. The bandwidth of a group is a multiple of the number of links in that group. For example, an IMA group with four T1 links has a bandwidth of 4 × 1.544 Mb/s. You can increase cell stream bandwidth beyond T1 and E1 rates up to a maximum of 8 × T1 or 8 × E1 rates.

PROTECTION PANEL

The OC3/STM1 1:N Protection Panel (90-9785-01) enables 1:N line card redundancy protection for STM1/OC3 MS electrical and optical interfaces. Twelve vertical card slots on the panel are organized into two 1:N protection groups with each accepting one protection IO (PIO) and up to five working IO’s (WIO’s);

Install the OC3/STM1 1:N Protection Panel in a 19-inch equipment rack. The panel can be flush-mounted or mid-mounted in a rack.

Figure 5.3-6: 7670 ESE OC3/STM1 1:N Prtection panel

MAU AND SFP

The Protection MAU is used to support 1:N Line Card Redundancy for STM1/OC3 MS line cards. The Protection MAU is a mandatory component for both electrical and optical 1:N LCR configurations. It must be used with the protection card of a protection group. The Protection MAU connects to the 64-pin telco connector located at the back of the shelf.

5.6. 7670 ESE CAPACITY AND DIMENSIONING

5.6.1 7670 ESE CAPACITY

The single-shelf 7670 ESE can handle up to 320P E1/T1 (ATM/IMA) with 1:1 redundancy for control board and 5:1 board redundancy for line-I/O board.

The single-shelf 7670 ESE has a nonblocking 3.2GB/s switching capacity.

5.6.2 SUPPORTED CONFIGURATION

Various configurations are predefined; this helps at providing list of parts to order and pricing. These configurations are regrouped into two types:

• E1/T1 connectivity to NodeB

• OC3/STM1 connectivity to NodeB

For more details please refer to the MOPG ref [Ext_SC_001].

But for most of requirement the 7670 ESE will need to be designed on case by case basis according to port type and quantity requested.

Engineering Guidelines: 7670 ESE – Configuration fo r VP shaping (R)

An 7670 ESE configuration . with no additional line card (only the 4 port STM1 daughter board on the ECC) can be used to perform t he VP shaping on the Iub at RNC interface

Justification:

For swap purpose, as the VP shaping on the RNC1500 is not iso funtional with ex-Alcatel RNC, you will have to add a 7670 ESE to perform the VPA shaping. This configuration allow to connect up to 2 IubSTM1 with APS 1+1 protection.

6. 7670 TN MANAGEMENT

6.1. 5620 NM EQUIPEMENT AND FUNCTION

Refer to 5620 PEI

6.2. MANAGING THE NODE USING CPSS

Rule: 7670 TN – OAM Management (M)

The management of the 7670 TN is done only by the 5620NM. There is no integration in the W-NMS.

The dialogue between the 7670 TN and the 5620 NM is based on the CPSS architecture, even if there is only one 7670 equipment.

Rule 6.2-1: 7670 TN OAM Management

6.2.1 CPSS OVERVIEW

CPSS messages carry the following types of information:

• control information that allows the network management system to send commands to the nodes

• statistical information that allows the network management system to gather performance information

• alarm information that enables the network management system to gather diagnostic information

• configuration status information from the nodes

CPSS MESSAGES

CPSS messages can travel out-of-band via IP connectivity between the 5620NM and the node or in-band over frame relay or cell relay PVCs, or E1 CE ports between the nodes and the 5620 NM.

The frame relay PVC connects one node to another node, which connects to the network management system through a cell relay or Ethernet connection.

The cell relay PVC connects directly to the network management system, or to a cell relay link from another node, which connects to the network management system through a cell relay or Ethernet connection.




E1 CE ports provide the means of transporting 16 kb/s CPSS frames in-band to far-end TDM equipment. The 5620 NM uses CPSS frames to control network equipment, shown in Figure 73-1.

Figure 6.2-1: CPSS in-band network topology

Figure above shows the 5620 NM generating CPSS data over selected timeslots of the SPRITE card E1 interface. The 3600 MainStreet node, situated between the SPRITE card and the E1 CE port on the 7670 ESE, is configured to carry 16 kb/s of CPSS data over the E1 timeslots. Data from the 3600 MainStreet node to the 7670 ESE is transmitted over the two least significant bits in the octet of the timeslots. ATM VCs cross-connected to the timeslots carry the data over the network. At the far end of the network, each VC is cross-connected to a channel group configured to carry TS0 of an E1 CE port. The two least significant bits received from each octet are buffered in the E1 CE until four bits are received and they are transmitted on the next E1 frame. This completes the link to the far-end equipment. The operation is reversed in the opposite direction.

You can use equipment other than the 3600 MainStreet node to transmit CPSS data between the ATM network and the 5620 NM. The equipment must be capable of transmitting 16 kb/s CPSS over E1 timeslots using the two least significant bits in each octet to transmit the data.

CPSS GATEWAY LINKS

CPSS messages travel between the active and standby 5620 NetworkStations, and each system through in-band or out-of-band CPSS gateway links. In-band CPSS gateway links are cell relay links. The active and standby 5620 NetworkStations need cell relay NICs to attach to a cell relay network in-band. Out-of-band gateway CPSS links are Ethernet links connected to the system ECCI, which physically connects to the same Ethernet LAN or extended LAN as the active and standby NetworkStations. See Figure below.




You can collocate one or more Delegate NetworkStations on the same Ethernet LAN or extended LAN as the active and standby NetworkStations. The Delegate NetworkStations do not contain a database, but do provide additional user interfaces.

Figure 6.2-2: CPSS network topology

CPSS NODE TYPES

There are three types of CPSS nodes:

• stub node

• routing node

• leaf node

A stub node is a 7670 ESE that terminates or originates CPSS traffic; stub nodes do not route CPSS traffic. Use stub nodes as feeders at the edge of the network to increase the fanout capability of the in-band CPSS link.




A routing node is a 7670 ESE that can route CPSS traffic. A gateway is a routing node that handles CPSS communications between the network management system and a CPSS domain.

A leaf node consists of a separate access device that can be configured as an additional node to a stub node or router node on a 7670 ESE. For more information about configuring a leaf node, refer to the 5620 NM documentation.

CPSS ADDRESSES

You must assign each node a unique address within the CPSS network. The CPSS address consists of two parts: a domain number and a node number.

CPSS DOMAINS

You can reduce CPSS routing complexity and improve CPSS performance, scalability and reliability by organizing nodes into groups called domains. You can create up to 60 domains; each domain can have up to 250 nodes. All 250 nodes can be routing nodes.

Each routing node in the domain knows the CPSS topology of its own domain only. Each gateway router also knows about the network management domain. For CPSS traffic, each stub node is aware of only the node or nodes to which it has an active CPSS connection.

Each domain must have at least one routing node (the gateway) that connects to one or more network management systems through Ethernet links or cell relay links, or through both Ethernet and cell relay links.

To create a gateway, configure the node type as routing node and configure the CPSS links with the network management systems as net-mgr. See the 5620 NM documentation for more information about CPSS requirements.

For fault tolerance, set up your network so that there is more than one gateway in each domain, and so that each node has CPSS links to at least two other nodes.

Within a domain, nodes use frame relay or cell relay links to carry CPSS traffic between nodes. Each node in the domain must have a direct physical link to at least one other node in the domain. Although physical links can exist between nodes in different domains with customer traffic routed over them, do not configure CPSS links to nodes that are not in the same domain.

You assign a node to a domain by configuring a domain number for the node; you must also configure the node with a CPSS node number that is unique within the domain.

CPSS LINKS AND PATHS

Table below lists the valid connections between the types of CPSS nodes. The nodes must be in the same domain. Note that a routing node that serves as a gateway also connects to the network management system.




Table 6.2-1: Valid connections for CPSS

When you connect a routing node to more than one other routing node, the node transmits and receives CPSS traffic based on the lowest end-to-end path cost between the source and destination nodes.

When you connect a stub node to more than one routing node that connects to the active 5620 NetworkStation, the stub node can use different links for transmitting and receiving CPSS traffic. The stub node transmits CPSS traffic over the link with the lowest configured CPSS path cost. When the lowest path cost is the same for two or more CPSS links, the stub node transmits over the lowest cost link that connects to the node with the lowest node number. If the gateway or routing node loses connectivity with the active 5620 NetworkStation, the stub node uses the same criteria to select a link to another connected gateway or routing node. A stub node connected to more than one gateway or routing node receives CPSS traffic from the gateway or routing node based on the lowest end-to-end path cost of reaching the stub node.

Configure CPSS links between nodes that are in the same domain, and between the gateway nodes and the active and standby 5620 NetworkStation. A routing node supports five CPSS links from the node to the active and standby NetworkStations, router network stations, or statistics collectors within the same domain; a routing node supports up to 15 CPSS links to other routing nodes and up to 60 CPSS links to stub nodes.

You can configure more than one CPSS link between two adjacent nodes. The CPSS links can use the same port or different ports. Only one of the CPSS links between two nodes is active; the inactive links have a status of parallel link and do not carry CPSS traffic. The active link is the first link to establish communications between the two nodes. If the active link develops a fault, its status changes to down and the first parallel link to establish communications between the two nodes becomes the active link.

You can configure the sustained and peak rate for gateway CPSS connections over ATM from a minimum of 100 kb/s up to the line rate.

CONFIGURATION PARAMETERS

CPSS DOMAIN NUMBER

The CPSS domain number must be in the range 1 to 60; the default is 1.

Routing node Stub node Leaf nodeRouting Stub Leaf

Node type at one end of CPSS link Node type at other end of CPSS link




CPSS NODE NUMBER

The CPSS node number must be in the range 1 to 254 and must be unique within the domain. The screen shows the default as Unassigned.

CPSS CLASS A ADDRESS

The CPSS class A address must be in the range 1 to 126; the default is 10. The system assigns the default CPSS class A address automatically; you do not need to configure it. If you change the class A address, it must be different from the IP address for the node and the in-band IP address (if configured), and must not be an address used by another company. All elements in the same network, including a 5620 NM must have the same CPSS class A network address.

CPSS NODE TYPE

When you change the node type, the CPSS links restart; which causes a temporary disruption in CPSS traffic.

By default, the 7670 ESE node type is configured as a stub node. For this node configuration, in-band CPSS connections may only occupy a maximum bandwidth of 64 kb/s. This value is nonconfigurable.

You can configure bandwidth for in-band CPSS connections on a routing node. See REF xxxx technical pratices.

6.2.2 CONVERTING CPSS TO IP:

This formula will not be of much use to most of us as the /opt/netmgt/install/ipcvt tool will do this calculation for you. I needed to figure this out to use with a different application that does not have access to the ipcvt tool so I though I'd add it here to save time for anyone having to figure this out again.

Note: the ipcvt tool does not do the calculation the same way as my formula. As well, this formula does not calculate the IP address for minor nodes(Ex. FRE cards).

However, for those of you who might need a formula to do this in the future here it is.

The first thing we need to know is the format for an IP address. It is made up of four fields separated by periods or "dots" as they are commonly referred to. Example: "138.120.136.228" For the purposes of my formula we will break the format of the IP address into four distinct variables as follows: A.B.C.D

The second thing we need to know is the nodes CPSS address. It is made up of two fields separated by periods or "dots" the same way each field of an IP address is separated. Example: "20.972" For this formula we will break the format into two distinct variables as follows: X.Y

X = Domain number.

Y = Major node number.




A = the ClassANetAddress. By default the 5620 uses "10" which is why we occasionally hear people referring to a nodes "10 dot address."

B = ( X * 4 ) + INT ( Y / 64 )

C = (Y - (INT ( Y / 64 ) * 64 )) * 4 + 3

D = this is a constant which always equals 253.

As an example the CPSS address of 20.972 will provide the nodes "10 dot address" of "10.95.51.253"

6.3. W-NMS EVOLUTION

Feature OAMx.x 33882 for FM in W-NMS is under discussion and will be implemented.




7. 7670 TN ENGINEERING RULES

7.1. 7670 DIMENSIONING

Dimensioning of the 7670 TN (RSP or ESE) is done in 3 steps.

• First, list all equipments that need to be connected through the transport node. This will lead to the exhaustive list of the interfaces that need to be managed and their definition (type, length, connection specificity and quantity).

• Second, this is the HW selection step: ESE or RSP. Then list the cards requested (type, quantity.

• Third, we need to check at the end that there is no engineering limit over passed.

Engineering Guidelines: 7670 RSP/ESE – Dimensioning approach (R)

Dimensioning of the 7670 TN (RSP/ESE) is mainly cou nting interfaces in/out and defining clearly the type of these interfaces and f eatures that need to be supported.

Justification:

In our case, we are not designing a backbone but just interconnecting two equipment in a point-to-point mode. The processing and datafill capacity is not a limiting factor for our usage of the 7670. The interface dimensioning is done at the other equipment that you need to inter-connect, in our case it is mainly done at RNC level.

The important point is the type of interface that is required ( STM1 Chanelized or not chanelized, E1,…) and the feature that are required (IMA or not IMA, APS 1+1, redundancy 1:N,…)

Guideline 7.1-1: 7670 RSP/ESE – Dimensioning approach

7.1.1 STATUS OF INTERFACE TO BE MANAGED

You must define a local area, list of equipment that need to be interconnected. This is mainly the UTRAN (list of NodeBs and RNCs) but other equipment may be added as Core Network. Note that you can have multiple RNCs in a local area.

You need then to define where all these equipments are located. Are they in the same room ? if not what is the distance between them ? And you need to define how they are interconnected. These are the questions to answer :

• Type of connections : E1, T1, STM1, STM1 channelized,..

• Do we have IMA? Note that IMA is mandatory on Iub to carry HSDPA traffic.




• Do we have APS? Note that APS is mandatory for Iub on RNC.

• Specification of the connection : Optical, electrical, length, type of connector,

• Quantity by type.

Please refer to various TEG (Transport Engineering Guide) to finalise this list.

7.1.2 HW SELECTION

First of all you must select the type of shelf : RSP or ESE by using the table below.

Table 7.1-1: HW selection

Note (1) these boards are not presented in this document. Please refer to [Ext_NTP_002]

Some type of interface can be handled by both RSP and ESE, so decision will be done on the quantity to be managed. The RSP has a higher capacity than the ESE.

Switching Capacity Number of STM1 Ports7670 RSP shelf 50 Gbit/s 224

(or 112 with APS 1+1)7670 ESE Shelf 3,2 Gbits/s 20 (1)

(or 10 with APS 1+1)

Table 7.1-2: HW type capacity

Note (1) With ECC line module and Dual Homing feature.

Then to determine the number of board needed, please see each board definition in previous chapter and see how many ports each board can handle. Do not forget to take into account the APS functionality.

7.1.3 CAPACITY CHECK

Use the following tables to validate the number of board

Table 7.1-3: 7670 ESE Board capacity

Table 7.1-4: 7670 RSP Board capacity

Engineering Guidelines: 7670 RSP/ESE – HW Selection (R)

HW selection between RSP and ESE is not only done o n interface availability. It is strongly dependant of the capacity needed.

Justification:

When there is more than 320E1 and more than 8 STM1(or 4 STM1 with APS 1+1) interface reqired,. instead of having multiple ESE, you can have one RSP with STM1 and add external equipment, as the PSAX, or equivalent, to do the STM1 to E1 conversion.

When a lot of interfaces need to be managed, special attention must be required as it is nearly a little backbone that needs to be designed.

7.1.4 DIMENSIONING EXAMPLE

The aim is to dimension a TN to interconnect a RNC to 50 nodeB and a Core network (CS and PS).

The RNC is with the 7670 TN (in the same room), is connected to 50 NodeB with 2 E1 by NodeB.and is connected to Iu CS and PS by one STM1.

One group of 25 NodeB are connected directly by E1 120Ω

The second group of 25 NodeBs is connected through a backbone and final connection to the RNC room is with Chanelized STM1. APS 1+1 is requested for the backbone connection.

Note that it is an example and normally all interface dimensioning (Iub, Iu and Iur) must be done using relevant tools as it is strongly dependant of the Traffic model and the number of subscriber.

Figure 7.1-1: Network topology for dimensioning example

STEP1 LIST OF INTERFACE

Iub interface on NodeB side. The need is :

• 50 E1s with IMA, 120 Ω

• 2 OC3/STM1 channelized : 50 E1 can be carried by 1 OC3/STM1 and need 2 due to APS (distance less than 15 km type SMF)

IuB, IuR Iu interface on RNC side :

• IuB : 2 STM1 (APS)

• Iu : 2 STM1 ( suppose Iu CS & Iu PS on same link, APS)

Iu interface on core side :

• 2 STM1 (APS) Distance less than 15km, type SMF

STEP2 : HW SELECTION

As we need E1 connectivity, we must select the 7670 ESE.

List of boards :

• 2 * 32-port T1/E1 MS card with IMA module to handle 50 E1

• 2* 1-Port STM1/OC3 MS (1 card handle 63 E1, twice for APS)

• 2 *4-Port OC3/STM1 module on the ECC board to handle the 6 (3+3) OC3 STM1 note these module cannot support channelized E1.

Note 1: a third 32 port T1/E1 board will be added to ensure line processing board redundancy.

Note 2: the E1 panel distribution will be added. As it supports 16 ports, 4 items will be needed.

STEP 3 : CAPACITY CHECK

Only 5 slots over 12 will be used so there is no issue.

Bandwidth limitation need to be check, basically it is the sum of traffic incoming and outgoing from the RNC.

CARD LOCALISATION IN THE SHELF :

Due to redundancy 1:N for 32ports T1/E1 line cards, we will reserve the 6 first slots for E1 connectivity:

• Slot 1 for Protection cards

• Slot 2 & 3 for Active Cards

• Slot 4 to 6 for future expansion.

OC3/STM1 cards will be in slots 11 & 12.

This will allow room for additional E1 extension if it requires more than 3 more E1 cards; we will be able to add E1 cards from slot 7 to 10 and E1 cards added in the second protection group must have the protection card in slot 7.

The CIQ tableau should looks like this table :

Virtual Path Aggregation shaping

VPA shaping is a commissioning capability that aggregates the traffic of multiple VCCs terminating on the same VPI, and shapes the aggregated traffic on the egress port of a node to a particular VPC traffic descriptor, rather than shaping individual VCCs to their own traffic descriptors.
