2 Introduction

SURPASS hiT 7060 is a multi-service provisioning platform with add/drop, terminal and cross-connect functionality for universal installation at all network levels.

All applications can be implemented using a single subrack. Reconfiguration during operation is possible.

SURPASS hiT 7060 transports data signals and standard voice based traffic over one single platform. For transporting data in the most economic way, the SURPASS hiT Series product line combines technologies such as Generic Framing Procedure (GFP), Link Capacity Assignment Scheme (LCAS), and Resilient Packet Ring (RPR) with the reliability and robustness of SDH networks and a quality of service.

SURPASS hiT 7060 network elements provide full cross-connectivity between all interfaces. The capacity of the switching network is up to 448 × 448 STM-1 equivalents. This applies to the layer VC-4 and to all cross-connection types (unidirectional, bidirectional and broadcast). SURPASS hiT 7060 is applicable as

• TMX (terminal multiplexer) • ADM (add/drop multiplexer) or • LXC (local cross-connect)

in multiservice transport and aggregation/switching network applications.

”State-of-the-art” protection switching mechanisms are supported to enable an optimum network with the very highest reliability to be realized – depending on the relevant network topology and the requirements of the network operator, see Chapter 5.10.

SURPASS hiT 7060 is single subrack equipment.

For detailed information about the features of SURPASS hiT 7060 see Chapter 3.

4 Network Applications The network elements can be used in a straightforward way of creating point-to-point connections, linear chain configurations and ring configurations.

According to requirements, equipping for the following application scenarios is possible:

– Terminal-to-terminal topologies (see 4.1)

– Linear topologies with add/drop function (chains) (see 4.2)

– Ring network functionality (see 4.3)

4.1 Terminal-to-Terminal Topologies Terminal-to-terminal links are supported by SURPASS hiT 7060 network elements in TMX application, optionally with 1+1 MSP for STM-1 and STM-4 interfaces.

Fig. 4.1 shows a straightforward point to point network with one TMX at the transmitting end and another at the receiving end and additionally a MSP protection switching.

Fig. 4.2 Add/Drop Function within a Linear Chain

An ADM is normally used at an intermediate site to add/drop client traffic. In Fig. 4.2, an ADM is located in between two TMXs. At the ADM, selected traffic is added/dropped at VC-4 or VC-12 level; through connected traffic transparently passed through.

The use of MSP between the NEs is preferred for redundancy reasons but not mandatory.

5 System Description The following sub-chapters give a functional overview of the main features of SURPASS hiT 7060 uncoupled to the physically interfaces. For information about hardware relevant features please refer to Chapter 6.

5.1 Subrack

The SURPASS hiT 7060 reuses SURPASS hiT 7060 chassis with the following modifications inside the chassis:

(1) New and lower capacity backplane and CC

(2) New air-intake design

The SURPASS hiT 7060 subrack physical appearance is shown below.

The physical dimensions of the SURPASS hiT 7060 are 442mm (wide) × 610mm (high) × 299 mm (deep). The racks used comply with the dimensions recommended by ETSI (European Telecommunications Standards Institute): W = 600 mm, H = 2200 mm and D = 300 mm (ETS 300 119). All external interfaces are front access. It is designed for easy maintenance and installation, and supports 600mm or 19” rack-mount installations.

Up to two SURPASS hiT 7060 subracks can be installed into a 2200mm or 2600 mm high ETSI rack or an EIA 310 19” rack. The space between the two subracks should be at least 5-rack-unit apart.

Fig. 5.2 Functional Block Diagram

On the line side, the send/receive modules (SDH) carry out the conversion to optical/electrical signals. The SDH cards can be equipped with various transceiver modules (SFP modules) in several distance variants up to 2.5 Gbit/s.

On the tributary side, the SURPASS hiT 7060 supports various PDH, Ethernet, and STM-N interfaces.

The central element of SURPASS hiT 7060 includes system controller, cross-connect matrix, timing functions, and maintenance panel.

Tab. 5.1 User Data Interfaces

5.2.2 Switch Fabric Functions The switching device provides HO and LO switching at the same time.

In the switch matrix, an SNCP is implemented for each VC-4/VC3/VC12 switching hierarchy and input signal. The configuration of the switch matrix and of the SNCP is done by software support. Capacity of the Cross-connect Matrix

The cross-connect has the following cross-connection capacity:

HOCC: 70G (448 × 448 VC-4s)

LOCC: 5G (2016 × 2016 VC-12s, or 32 × 32 VC-4 equivalents) Cross-connection

All types of cross-connections can be realized. The switch matrix is a non-blocking square structured matrix for point-to-point and point-to-multipoint connections. Granularity

The configurable and simultaneously usable switching hierarchies of the matrix are VC-4, VC-3, and VC-12. HO and LO VC-n Connectivity

The switching matrix allows the following connections:

− Unidirectional connections

− Unidirectional point-to-multipoint (including 1+1 SNC head end)

− Bi-directional connections

− Broadcasting (1 m, with m unlimited)

− Drop and continue (broadcast 1 2 + SNCP tail end)

− Selector 2 1 (protected tail end for 1+1 SNCP) Concatenation

Virtual concatenated VC-12 and VC-4 signals are supported. Protection switching for virtual concatenated signals VC-4 and VC-12 is also supported. The group of constituent paths that belong to a concatenated signal is determined by the Telecommunication Network Management and written to an internal configuration table. Using this information, the SURPASS hiT 7060 software is able to set signal fail or signal degrade alarms for all paths of a concatenated signal channel. In order to keep the (differential) delay of the signals low,


24 A42022-L5969-A 51-1-7618

all constituent paths of a concatenated signal must be on the same optical trail; it results in a bundling rule for the Telecommunication Network Management.

5.2.3 Multiplex and Mapping Functions The SURPASS hiT 7060 transmits SDH and PDH signals. Fig. 5.3 shows the organization and relationship of SDH and PDH multiplex structures.

Fig. 5.3 SDH/PDH Multiplex Structures

5.2.3.1 SDH HO/LO Multiplexer and Mapping Functions The SURPASS hiT 7060 implements the following HO/LO multiplexing and mapping methods: • VC-4 containers are aligned (with frame offset information) with an AU-4, acc. to ITU-T

G.707. The AU-4 may further be mapped via AUG-1 into STM-1 or via AUG-1and AUG-4 into STM-4.

• VC-3 containers are aligned (with frame offset information) with a TU-3, acc. to ITU-T G.707. The TU-3 is further mapped via TUG-3 into VC-4.

• VC-12 containers are aligned (with frame offset information) with a TU-12, acc. to ITU-T G.707. The TU-12 is further mapped via TUG-2 and TUG-3 into VC-4.

5.2.3.2 PDH Mapping into SDH Containers

The SURPASS hiT 7060 implements the following mapping of PDH signals on SDH containers:


A42022-L5969-A 51-1-7618 25

• 2-Mbit/s signals are mapped into a VC-12 asynchronously, acc. to ITU-T G.707. The VC-12 is further mapped on a VC-4, via TU-12, TUG-2 and TUG-3.

5.2.3.3 Ethernet Packet Multiplexer and Mapping Functions The SURPASS hiT 7060 supports Ethernet frame mapping into SDH containers. So LAN traffic can be transported over different SDH payload sizes (requires encapsulation by using an appropriate protocol and mapping of the resulting frame into a SDH container).

For encapsulation, the Generic Framing Procedure (GFP-F acc. to ITU-T G.7041) protocol is used. The encapsulated protocol frames can be mapped into different SDH containers using the virtual concatenation technique.

Ethernet Mapping into SDH Containers

SURPASS hiT 7060 supports a flexible mapping scheme: Ethernet Mapping into LO virtually concatenated Containers

Mapping into VC12, VC-12-mv (m = 2 to 46).

This mapping function is supported for the Fast Ethernet ports.

Encapsulated GFP-F frames can be mapped into different Low Order container sizes providing a scalable solution that can cover network applications with very different transport capacity requirements.

GFP-F Mapping

The Generic Framing Procedure (GFP) is supported by the Fast Ethernet and Gigabit Ethernet interfaces.

GFP provides a generic mechanism to adapt traffic from higher-layer client signals over an octet synchronous transport network. This is a simple and robust encapsulation method for packet traffic. All of the relevant MAC layer information, from destination address through Frame Check Sequence (FCS) included, is preserved intact by the mapping.

The SURPASS hiT 7060 uses a PDU-oriented, frame-mapped adaptation mode (GFP-F) for client signal adaptation.

GFP-F does not rely on flag characters, and associated control escape octet, for frame delineation purposes as HDLC does. Instead, GFP-F uses a variation of the HEC-based (Header Error Control) frame delineation mechanism defined for Asynchronous Transfer Mode (ATM). This avoids non-deterministic expansion of the client signal due to insertion of control escape characters.

5.3 Ethernet Transparent or Layer 2 Functions The SURPASS hiT 7060 supports Ethernet data transparent transmission and Layer 2 functions as follows:

− FE port auto negotiation, flow control, IEEE 802.3 and Ethernet II frame structure

− Ethernet performance monitoring and alarms

− VLAN and double VLAN tagging

− Access Control List (ACL) based on MAC addresses

− Rapid Spanning Tree (802.1w)

− Layer 2 multicast functions (including static provisioned multicast and IGMP Snooping multicasting functions)

− Rate limiting function at per port and per VLAN, the rate range of each port is from 200kbps~100Mbps (FE), and the rate provisioning granularity is 1kbps.

− 802.1p QoS/CoS based on Ethernet port and/or VLAN

5.4 Clock Pulse Supply, Synchronization The clock of every network element (NE) may be synchronized by a very accurate timing source, normally by a primary reference source (PRC) according to the master-slave principle. The SETS is responsible for generation of system and output clock signals.

According to the ETSI recommendation, T3 and T1 are the synchronization timing sources, T0 is the internal NE system clock and T4 is the timing output interface.

Selection SETS

T4

T0

T3

T1

Fig. 5.4 Timing Source Selection

5.4.1 Available Timing Sources The synchronization of the SETS of the SURPASS hiT 7060 is derivable from any of the following external ports:


28 A42022-L5969-A 51-1-7618

− From any STM-1/4/16 ports (T1), two T1 references are managed on the SETS. The two T1 references are connected to the input of the SETS by two busses, each card is connected with busses, and the T1 of each port can be sourced on any bus,

− From an external 2-MHz port (T3).

− From internal Stratum 3 clock (ITU-T G.813 Option 1)

A SURPASS hiT 7060 NE can run in free running, holdover, or locked mode. The normal synchronous mode is locked mode. If all of the reference sources fail, the system switches to holdover mode.

A Synchronization Status Message (SSM) signal can be used to transfer the signal quality level throughout a network. This will guarantee that all network elements will always be synchronized to the highest quality clock available.

The SURPASS hiT 7060 supports SDH SSM algorithm on all STM-N interfaces and on the framed 2 Mbit/s synchronization output signal (connected to the station output clock):

SSM function support can be user provisioned as “enabled or disabled”. When the SSM function is disabled in the NE, all STM-N interfaces and the framed 2 Mbit/s synchronization output signal interface will send out a DNU (do not use for sync) signal.

There are 4 possible quality levels specified in the SSM for timing reference sources: PRC, SSU-A, SSU-B, and SEC. In addition, DNU is specified in SSM. The quality of each timing reference source can either be retrieved from the incoming the SSM or provisioned from the network management system.

The SURPASS hiT 7060 supports the synchronization source switching algorithm based on SSM defined in ITU-T G.781.

The wait-to-restore (WTR) time for timing reference source is between 0-12 minutes and can be set from the network management system in minute increments. The default value is 5 minutes

5.4.2 T0 System Clock The T0 system clocks are used in the NE for traffic processing, OH/DCC busses, internal system communication between the system controller and each card, and for the distribution of the absolute time.

T0 clocks to each LC and MC slot include the following three signals:

− Clock signal 77 MHz; point to point distribution.

− Frame clock signal 2 kHz; point to point distribution.

− Absolute time signal 1 Hz; point to point distribution.

T0 clocks to each TC slot include the following three signals:

− Clock signal 19 MHz; point to point distribution.

− Frame clock signal 2 kHz; point to point distribution.

− Absolute time signal 1 Hz; point to point distribution.

All cards receive the T0 clocks.


A42022-L5969-A 51-1-7618 29

5.4.3 Timing Output Interface The System Management Interface Panel provides the following interfaces to offer synchronization to external devices:

− 2 Mbit/s port

5.4.4 Real Time Clock For time stamps (time and date) in error and operational messages of the SURPASS hiT 7060 a real time clock is available (within the SETS).

The date and time for the real-time clock within the NE can be set and requested from LCT/OS.

5.5 Laser Safety Shut-down To prevent possible personal injury by emerging laser light in the case of line interruption (e.g. fiber break), the SURPASS hiT 7060 equipment contains a laser safety shut-down function (ALS Automatic Laser Shut-down) according to ITU-T G.958 and ITU-T G664. In the case of signal failure at the optical receiver of SURPASS hiT 7060 equipment, the laser transmitter is switched OFF in this equipment for the opposite direction and thereby the disturbed field is taken out of operation. The laser transmitter is then switched ON cyclically every 100 s for approximately 2s for testing. If the receiver of the concerned device receives a valid signal again, the laser transmitter of the opposite direction is immediately put into continuous operation again.

When switching ON internal power supplies or after a laser switch-off caused by total failure of the power supply in the telecommunications center, the laser transmitter(s) must be forced switched ON for approximately 2s after the permissible operating conditions have been reached. In this way the line is automatically put back into operation.

In the case of line interruption or for maintenance work, the laser transmitter must be switched on manually for approximately 2s or approximately 90s (test purposes). The transmitter is switched back ON via the operating terminal.

No ALS function is supported for Ethernet interfaces. These interfaces fulfill the requirements of laser hazard level 1 without ALS.

5.6 External Alarm Interfaces Failures signaled by any cards are processed by the main controller of the device, which forwards the detected alarm information to the alarm interfaces. The alarm interfaces are accessible via an alarm connector.

The SURPASS hiT 7060 alarm interfaces provide two outputs:

− Major urgent alarm (triggered by any Critical or Major alarms)

− Minor non-urgent alarm (triggered by any Minor alarms)

5.7 Engineering Order Wire The SURPASS hiT 7060 uses VoIP (H.323) technology to provide the EOW function on a DCC channel or uses external data network.


30 A42022-L5969-A 51-1-7618

The SURPASS hiT 7060 VoIP based EOW provides unicast and multicast calling, and broadcast communications.

5.8 User Channel The SURPASS hiT 7060 supports SDH User Channel (F1). The F1 user channel is in compliance with G.703 64Kbit/s electrical interface.

The SURPASS hiT 7060 can provide up to four F1 user channels (ITU-T Recommendation G.703 compliant). The four use channel interfaces (EOW1/2, EOW3/4) are located on the system controller module front panel.

For each EOW/UC interface, it is possible to provision Slot, Port, and E1/E2/F1 that the interface will use to communicate with the remote station. The system provides four DB9 connectors for four channels of E1, E2 Engineering Order Wire channel and/or F1 user channel.

Users may select up to four channels from the system – up to three from each STM-N interface (each providing a 64 Kbit/s channel through the E1 (2,4,1) or user selectable E2 (9,7,1) or through the F1 (2,7,1) byte of for user data applications between regenerators or between a regenerator and a terminal (i.e. on regenerator sections). When E1, E2, and F1 are not used, an all ones pattern will be transmitted in the E1, E2, or F1 bytes and the received E1, E2, or F1 bytes will be ignored.

Usage is in conformance with ITU-T Recommendation G.707 and ETSI ETS 300417 standards. Byte-slips are allowed.

5.9 Software/Firmware The System Controller (SC) board is equipped with micro controllers for monitoring, controlling, and maintaining status information. They are programmed with embedded firmware held in Flash-EEPROMs.

A software download facility is available. The download is provided via element manager or local craft terminal, for both remotely or locally.

The internal configuration database of the system can be uploaded and downloaded. It is stored redundantly and robust to any card failure.

5.10 Protection Switching SURPASS hiT 7060 supports the following SDH traffic protection functions:

- traffic protection functions on the STM-N multiplex section layer (Linear MSP) and

- subnetwork connection protection (SNCP) functions on the VC-4, VC-3, and VC-12 path layers.

Traffic protection functions are partly coupled with equipment protection features; this is in general implicitly achieved by including some HW components (e.g. SFP modules) within a protected signal section.

5.10.1 1+1 Linear Multiplex Section Protection (MSP) Protection switching is realized in the equipment according to the relevant ETSI/ITU-T standards ETS 300417-3-1 and G.841, respectively.

In 1+1 Linear MSP, the client traffic is always transmitted over the working and protection path simultaneously (MSP bridge).

In case of fiber break (Fig. 5.6), the SDH card detects the fault and the MSP selector automatically selects the incoming traffic from the protection path.

In SURPASS hiT 7060 Linear MSP is realized on per port basis. All related interfaces offer at least two ports and therefore it is not necessary to have a dedicated working and a dedicated


32 A42022-L5969-A 51-1-7618

protection card. As all the optical traffic cards offer hot changeable optical plug-in modules (SFPs) the 1+1 MSP protection always came with some kind of hardware protection.

In SURPASS hiT 7060 MSP operates in single-ended mode (revertive or non-revertive).

All SDH traffic interfaces of SURPASS hiT 7060 support 1+1 MSP protection scheme.

5.10.1.1 MSP Protection Characteristics - Architecture: 1+1

- Switching type: unidirectional (single ended) or bidirectional (dual-ended)

- Operation type: revertive or non-revertive

- The wait-to-restore (WTR) time for MSP is between 1-12 minutes and can be set from the network management system in second increments. The default value is 5 minutes

5.10.1.2 Criteria for Initiating the Protection Switching Process Linear MSP can either be initiated automatically or manually using the operating terminal/OS.

• Internal switch requests:

− SF (from LOS, RS-LOF, MS-AIS, RS-TIM, MS-EXC)

− SD (from MS-DEG) • External switch requests

− One at a time selectable from possible values:

− Lockout of Protection, LP

− Forced Switch, FS_P (working traffic to protection line)

− Forced Switch, FS_W (working traffic to working line)

− Manual Switch, MS_P (working traffic to protection line)

− Manual Switch, MS_W (working traffic to working line)

− Clear

5.10.2 1+1 Path Protection Switching (Subnetwork Connection Protection, SNC/I)

The data signal is transmitted via two different paths and can be implemented in line or ring structures (Fig. 5.6). The SURPASS hiT 7060 supports SNC/I protection.

SNC protection is a linear protection scheme which can be applied on an individual basis to VC-n signals. It need not be used on all VCs within a multiplex section. It need not be used on all LO VCs within a HO VC. The SNC/I mechanism switches on server failures using inherent monitoring as defined in ITU-T G.841. A Protection Protocol is not required.

The switchover between the working and the protection path can be configured as “non-revertive” or “revertive” mode. In the “non-revertive” mode, if there was a switchover to the protection path as a result of a transmission fault, there is no automatic switchback to the original path once the fault is rectified, but only if there is a fault on this new path. In the “revertive” mode, if there was a switchover to the protection path as a result of the working


A42022-L5969-A 51-1-7618 33

path fault, there is an automatic switchback to the original path once the fault on the working path is rectified.

In SURPASS hiT 7060, the 1+1 SNC/I can be categorized into High Order SNCP and Low Order SNCP.

5.10.3 Shared Ring Protection Switching (MS-SPRING)

A MS-SPRING is a bidirectional (duplex transmission) ring where both directions of traffic transmission use the same set of nodes under normal conditions. When there is a failure on the working path, the traffic will be switched to protection bandwidth.

The changeover criteria are specified individually when configuring the network element. An automatic Protection Switching (APS) Protocol is required.

The switchover to the protection bandwidth occurs in “revertive” mode, i.e if there was a switchover to the protection bandwidth as a result of a working bandwidth fault, there is automatic switchback to the original path once the fault is rectified.

5.11 Operating Terminal SURPASS hiT 7060 LCT Network elements can be operated and monitored via the software SURPASS hiT 7060 LCT software.

The SURPASS hiT 7060 LCT is used primarily for local management and commissioning of network elements. For this purpose it is connected via the management interface and allows access to network element locally or remotely.

For further information about operation, control and monitoring via operating terminals SURPASS hiT 7060 LCT see SURPASS hiT 7060 LCT User Manual.

5.12 Connection to Network Management Systems

For more detailed information about the modules/cards see the following chapters.

6.3 Power Supply Card PWR

The power supply card supports -48V (range -40.5~-57.0 V) DC power. It converts the input supply voltage into regulated operating secondary voltages. The outputs are isolated from


A42022-L5969-A 51-1-7618 41

the input. All output circuits have a common reference point, which is connected to the grounding layers on the backplane.

A switch on the module allows user to turn on and off the power supply. There is one green color LED labeled PWR on the module. The “on” status of a LED indicates that the corresponding power supply is on; otherwise the power supply is off.

The power supply card is a pluggable module and is hot swappable. The SURPASS hiT 7060 supports dual –48V DC power supply. There are two power supply slots located on the bottom row slot PWR1 and slot PWR2.

One power supply card can be equipped in any one of the power supply slots to support the whole system. Faceplate

6.8 Cross-connect and Timing Card CC The CC card provides a cross-connect function and timing function. The following described these two functions.

6.8.1 Cross-connect Architecture and Capacity

The 70G/5G CC module provides 70G HOCC (448 × 448 VC-4s) and 5G LOCC (2016 × 2016 VC-12 or 96 × 96 VC-3 equivalent). The switching-matrix provides a non-blocking switching of all traffic at VC-12, VC-3, VC-4, VC-4-4c, and VC-4-16c levels. In other words, each VC-12 on any slot can be switched with any other VC-12 on the same module or on any other slots.

This module supports up to 9× 2.5G interfaces.

The 70G/5G CC module cross connect and backplane structure is shown in Fig. 6.10 below.

Fig. 6.10 CC Card Cross-connect Architecture

The following types of cross-connects are possible on both cross-connect units:

− Uni-directional

− Bi-directional

− Loop backs

− Multicast

6.8.2 Timing Function The Timing function selects a recovered clock from one of the line inputs, a station clock from the central office (two independent connections are provided), an E1 tributary input, or an internal Stratum 3 (supports ITU-T G.813 Option 1 Stratum 3) reference (on the cross-connect and timing module) as the system-timing reference. You can provision any of the clock inputs as a primary or secondary timing source. You can identify up to four timing references, which can be prioritized to provide protection. A slow-reference tracking loop allows the Timing function to synchronize to the recovered clock, which provides holdover if the reference is lost.

The System Timing References are:

− Station External Timing (1.5Mbps or 2Mbps) input/output

− STM-N Optical Network Interfaces

− STM-1, E1 client Interfaces

The SURPASS hiT 7060 can run in free running, holdover, or locked mode. The normal synchronous mode is locked mode. If all of the reference sources fail, the system switches to holdover mode.


46 A42022-L5969-A 51-1-7618

A Synchronization Status Message (SSM) signal can be used to transfer the signal quality level throughout a network. This will guarantee that all network elements will always be synchronized to the highest quality clock available.

The SURPASS hiT 7060 supports SDH SSM algorithm on all STM-N interfaces and on the framed 2 Mbit/s synchronization output signal (connected to the station output clock):

1) SSM function support can be user provisioned as “enabled or disabled”. When the SSM function is disabled in the NE, all STM-N interfaces and the framed 2 Mbit/s synchronization output signal interface will send out a DNU (do not use for sync) signal.

2) There are 4 possible quality levels specified in the SSM for timing reference sources: PRC, SSU-A, SSU-B, and SEC. In addition, DNU is specified in SSM. The quality of each timing reference source can either be retrieved from the incoming the SSM or provisioned from the network management system.

3) The SURPASS hiT 7060 supports the synchronization source switching algorithm based on SSM defined in ITU-T G.781.

4) The wait-to-restore (WTR) time for timing reference source is between 0-12 minutes and can be set from the network management system in minute increments. The default value is 5 minutes

6.13 Fast Ethernet Interface Card 6× FE/L2 Function

The Fast Ethernet interface cards provide the means to map Fast Ethernet client signals of type 10/100 BASE TX into VC-12-Xv for transport. This card has 6×10/100M Base-T IEEE 802.3 compatible Ethernet interface ports, and can provide traffic aggregation and transmission for up to 2 uplink connections.

There are two WAN ports on the network side. Up to 6 10/100M traffic can be aggregated to 1 or 2 WAN ports and forwarded to a SDH line interface for transmission. Given bursty


A42022-L5969-A 51-1-7618 53

nature of data traffic, aggregation of multiple port traffic into a single group of virtually concatenated containers allows a more efficient use of the available bandwidth.

This module supports following features: • GFP encapsulation (ITU-T G.7041/Y.1303)

• Low order virtual connection VC-12-Xv (X=1…46); the total available bandwidth on the network side is 1× VC-4

• LCAS function, with this mechanism, the allocated SDH bandwidth for an Ethernet link can be dynamically reconfigured without disturbing the existing traffic flow.

• FE ports support auto negotiation, flow control, IEEE 802.3 and Ethernet II frame structure

• Ethernet performance monitoring and alarms

• VLAN and double VLAN tagging, providing increased number of VLANs.

• Access Control List (ACL) based on MAC addresses

• Rapid Spanning Tree (802.1w), dramatically reducing restoration time

• Layer 2 multicast functions (including static provisioned multicast and IGMP Snooping multicasting functions), saving bandwidth on applications such as multi-media video

• Providing per port rate limiting function: the rate range of each port is from 200kbps~100Mbps (FE), and the rate provisioning granularity is 1kbps.

• Providing per VLAN rate limiting function: The rate range of each VLAN is from 200kbps~100Mbps (FE), and the rate provisioning granularity is 1kbps.

• Providing 802.1p QoS/CoS based on Ethernet port and/or VLAN

• Each FE input interface has a buffer to support bursty data traffic transmission. The input buffer of FE interface can accommodate up to 256 frames. Each FE interface has also 4 output queues, each of which has a buffer that can accommodate up to 496 frames to be sent out. As each input buffer and output port buffers are independently using the dedicated memory spaces, instead of sharing any common memory space, there will be no mutual influence between the input buffer and the output buffers.

This card can be installed in any slots from LC1 to LC11.

7 System Control and Monitoring

In addition to the payload signals, control, monitoring and customer-specific data signals can be transferred in the section overhead of the STM signals.

To ensure high operational safety, operation is continuously monitored by a network management system or by an operating terminal.

Network elements to which no operating terminal has been connected give information about the operational state (for support in the case of maintenance work) via built-in indication elements (see Chapter 7.1).

System control and monitoring is performed by the ‘System Controller’ (SC). The MSC communicates with the traffic cards via different internal interfaces.

The equipment provides SNMP/TCP/IP over Ethernet interface to the LCT. The equipment also provides a management interface to a Local Craft Terminal (LCT).

For feature enhancements or debugging, software download is possible for all units of the system. During download, the traffic is not affected.

The SURPASS hiT 7060 is integrated in the following management functions in conformity with the corresponding ITU-T Recommendations and ETS standards:

− Fault Management

− Configuration Management

− Performance Management

− Security Management

− The following are of particular importance:

− Alarm processing (e.g. AIS, FTP) for localizing faulty equipment in the transmission network.

− Fault diagnosis at card level (e.g. localizing a faulty card).

− Specifying and storing configuration data; these can be entered and requested by the network management system or the LCT.

− Determining the quality parameters according to the ITU-T Recommendation G.826.

− Administration of the access authorization in the LCT for various user classes with passwords.

General Fault Management Functions

Fault Management is concerned with the detection, localization, isolation, and reporting of failures of the transmission signals processed by the SURPASS hiT 7060 and of its equipment. The failures and the failure processing are differentiated in two failure classes:

Transmission Failures and Equipment Failures

In addition to these two failure categories, the SURPASS hiT 7060 supports external alarm contacts, which can be used for signaling any kind of failure.


56 A42022-L5969-A 51-1-7618

Failures are reported via the management interface to the LCT/OS and may also lead to alarm indications at the LCT (card indications, NE indications, and transport functions indications).

The tasks of the fault management function are listed below:

Detect anomalies

Derive defects by eliminating spurious anomalies and to report some of them to the fault management function

Trigger automatic maintenance actions (AIS insertion, Laser shutdown,...)

Perform alarm reduction through correlation of defects

Perform further alarm reduction through adjustable persistence checks

Time stamp alarm events using the system real time clock

Issue spontaneous alarm event notifications to the LCT/OS

Prevent the report of unwanted alarm event notifications according to configurable alarm forwarding

Report alarms to the local alarm system

Indicate fault states of replaceable units

Store alarm events and the alarm states in the current problem list for later retrieval

Support fault location for diagnosis and guiding of maintenance.

7.1 Indicating and Operating Elements of the Network Element

The indication elements (LEDs) on the cards (see 7.3.2) are a useful aid particularly if neither a Local Craft Terminal, LCT, nor a network management system have been connected to the SURPASS hiT 7060 equipment when an alarm occurs. The LEDs signal alarms at subrack and card level.

7.1.1 Operating Devices of the SURPASS hiT 7060

In the Subrack Front Panel of the SURPASS hiT 7060 there is an acknowledge key ACO for manual acknowledgment of the alarm messages.

7.1.2 Operating and Display Elements of the Cards

LED Displays of the Cards

To assist in maintenance work, there are two LEDs on the front of each card which are visible.

− A red FAULT LED to indicate card-internal alarms.

− A green PWR status LED to indicate card power supply status.

− Additionally to the red and the green LEDs which have the same behavior as on other cards the Ethernet cards contain yellow and green LEDs for each port giving information about Link Status and Link Activity to the operator and service technicians.


A42022-L5969-A 51-1-7618 57

Operating Elements of the Cards

No hardware settings have to be made on the printed circuit boards of the cards. The cards are configured by software commands from the operating terminal or from a network management system when commissioning or in the case of later changes.

7.2.2 TNMS-M The TNMS-M provides both element management and sub-network management functions. It supports ITU-T complied FCAPS function and extended these functions to the sub-network level. The TNMS-M not only provides SDH layer management functions, but also supports the management of Ethernet, RPR, and ATM services, as well as other data interfaces•The TNMS-M offers a TMF814 northbound CORBA interface to interact with the TNMS-Core. More detailed information of the TNMS-M is provided below: TNMS-M Architecture

TNMS-M is based on a distributed client, server and database architecture. The implementation technology is independent of operating systems, which enhances system compatibility. The modular software design allows the TNMS-M to provide integrated management of SDH, ATM, RPR, and Ethernet/IP networks in one platform and enables scalability for introducing additional new technologies. The TNMS-M allows multiple TNMS-M clients to manage the same network at the same time. Management at the Network Management Level by The TNMS-M or other higher-level network management system can be reached via the TMF814 northbound CORBA interface of the TNMS-M. Element Management Function

TNMS-M offers an advanced graphical interface to facilitate the configuration of each NE. Operations on NEs is shown directly on a graphic chassis view. A graphical interface of the NE shows modules and ports, which directly corresponds to the real ones being managed. This gives the operator real-time status information, facilitating the management process.

TNMS-M provides standard-based TMN capabilities, including

− Fault Management

− Configuration Management

− Performance Management

− Security Management

− System Administration Network Management Function

TNMS-M provides layered management capabilities. Networks and services of different technologies (TDM, ATM, RPR, Ethernet, etc.) carried over the same MSTP platform can be managed and optimized independently through graphical management interfaces, appearing as if they were independent networks. One network of MSTP equipment will appear to the user as three different networks: an SDH network, an IP/Ethernet network, and an ATM network. The TNMS-M offers a total view of the managed MSTP network elements. It provides many sophisticated network level functions in a user-friendly fashion. Graphical End-to-End Provisioning and Maintenance


A42022-L5969-A 51-1-7618 59

TNMS-M supports multi-service (TDM, ATM, RPR, Ethernet, etc.), graphical, end-to-end, and fast service provisioning. This makes the creation, maintenance and management of services significantly simpler for operators Utilization statistics of network resources and bandwidth

This helps service providers optimize their networks by discovering potential bottlenecks Topology Management

TNMS-M provides a variety of network topology information. For instance, the SDH synchronization topology enables direct view and real-time monitoring of the timing status and timing relationship between NEs. The TNMS-M shows the topology map with different icons to indicate different types of NEs and by using different lines to indicate different bandwidth and various other user-friendly features. Correlation Analysis Among Circuits, PM Data, and Alarms

Provides intelligent alarm correlation analysis to enhance trouble-shooting. Network Elements Auto-Discovery and Network Auto-Construction

For details on TNMS-M software components, see the TNMS-M User Manual.

7.3 Management System Protection

TNMS-M provides the following mechanisms to ensure system and data security:

(1) Database backup and recovery

The TNMS-M contains a database to keep all network and NE information. The TNMS-M is designed to allow operators to backup the database and to select the database backup methods as either a backup per request, or to perform backups periodically (using pre-defined tasks). All backups are maintained in the backup table. Operators can retrieve any backup copies as needed.

Database backup tool works independently of the TNMS-M network management system. This feature ensures that even if the TNMS-M network management system does not run, the database can still be backed up in time.

(2) MIB backup and recovery

A copy of the MIB in an NE can be transmitted to and saved at the TNMS-M or TNMS-M SURPASS hiT 7060 LCT. When the MIB fails, the backup copy of the MIB can be downloaded to the NE for use. The TNMS-M or TNMS-M SURPASS hiT 7060 LCT provides the switch over from the current MIB to the backup MIB. The system provides a separate MIB backup tool (integrated with database backup tool), which can do periodic backup and management.

(3) NE software recovery

The TNMS-M supports remote NE software download, and switch over between NE software loads.

7.4.1 Application Management Module The application management module is the application layer software in the embedded software system; its main function is to fulfill configuration management and monitoring for the NE. Via standard SNMP protocol, the application management module can inter-communicate with the network management system, fulfill cross-connect management, service protection configuration, performance monitoring, and alarm surveillance. The application management module can be divided into the following sub-management system functions:

– CC (Cross-connect) module

– FM (Fault management) module

– PM (Performance management) module

– TM (Timing management) module

– IFM (Interface management) module

– Data management module

– MSP, MSSPRING, and SNCP service protection module

Each software sub-system can be divided into two layers, Manager and Agent. The main function of Manager is to receive requests from network management system, and then


A42022-L5969-A 51-1-7618 61

convert them into operating commands, which will be sent to Agent. The Agent then receives operating commands from the Manager, and fulfills the configuration function via the interface provided by the hardware driven module. In addition, the Agent is in charge of collecting hardware information (for example, hardware failure and performance statistical data), and sending them to the Manger. After related processing, the Manager converts this data into information the network management software can read, and sends it to network management software.

7.4.2 Hardware Driver Modules

The SURPASS hiT 7060 NE hardware includes many integrated circuit chipsets. Hardware driven modules control these chipsets. The hardware driven modules provide the access interface between the hardware and the higher layer software (the application management module). The main functions of hardware driven modules include:

− Hardware initialization

− System auto testing

− Hardware configuration

− Interruption service

− Hardware information inquiring

− Alarm/Performance monitoring data collection and reporting

7.4.3 Real-Time Multi-Task Operation System

The embedded software in the SURPASS hiT 7060 NE was developed using the high performance VxWorks real time operating system. VxWorks is a reliable embedded software platform; it includes a high performance real time kernel, which supports preempting multi-task scheduling based on priority. It also includes task management, timing management, storage management, resource management, event management, resource management, message management, queue management and semaphore management. These basic functions offer powerful support for rapid, reliable application development.

7.4.4 SNMP Agent

The SURPASS hiT 7060 embedded software includes a standard SNMP agent module. The SNMP agent is responsible for responding to all EMS/SNM requests including information requests and action requests. It will also generate autonomous event reports to the EMS/SNM.

The SNMP communication protocol includes 3 operations: Get, Set, and Trap. Through these 3 combined operations, the SNMP Agent can fulfill all configuration management and alarm monitoring function via intercommunicating with the MIB in the NE.

The intercommunication process among the SNMP Agent, the MIB management module, and the application management module is as following: the SNMP Agent receives requests from network management software, and then sends these requests to the MIB management module. When the MIB management module receives requests it will cause the application management module to do related operations to achieve system management functions. At the same time, hardware driven modules and some application


62 A42022-L5969-A 51-1-7618

management modules may generate related events and data, which will be needed to report to network management software. This information will be sent to the network management software via the application management module invoking interfaces provided by the SNMP Agent and transmitting them by Trap.

7.4.5 MIB Management Module

The MIB management module is the interface of the management information database in the embedded software system of the SURPASS hiT 7060 NE. The MIB includes all configuration information and real time monitoring information in the NE. This information is managed by the MIB management module uniformly to accomplish information storage, recovery, retrieval, modification, and notification functions.

7.5 Management Protocols and DCC

The TNMS-M or SURPASS hiT 7060 LCT uses SNMPv2 protocols to communicate with SURPASS hiT 7060 NEs.

The SURPASS hiT 7060 system uses TCP/IP over the SDH data communication channels (DCC) or Ethernet LAN (RJ-45 connector) to provide a local or remote craft interface for management and monitoring. The SURPASS hiT 7060 supports the following two DCC channels:

− Regeneration Section DCC (D1-D3 bytes)

− Multiplex Section DCC (D4-D12 bytes)

In the SURPASS hiT 7060, DCC is supported on all STM-N interfaces. TNMS-M or SURPASS hiT 7060 LCT enables you to select which DCC is used on each STM-N interface. TNMS-M supports TMF 814 CORBA northbound interface.

8 Commissioning and Maintenance

8.1 Commissioning

If the SURPASS hiT 7060 has to be configured on initial commissioning, a Local Craft Terminal (LCT) has to be connected to the Ethernet interface of the SURPASS hiT 7060. The hardware and software requirements at the craft terminal are described in manual ITMN. The craft terminal offers a graphical, menu-driven user interface.

Detailed information for commissioning the SURPASS hiT 7060 equipment and the operating terminals is given in the SURPASS hiT 7060 Installation and Test Manual.

8.2 Maintenance

The alarm and maintenance concept of the system provides sufficient alarm information to localize and clear the fault at card level. No maintenance at regular intervals is required. Maintenance measures (e.g. fault localizing) can be carried out locally via the local management interface (LCT/ TNMS-M) or under remote control via the TCP/IP over DCC (LCT or a network management system).

Maintenance of the SURPASS hiT 7060 equipment is described in the SURPASS hiT 7060 Troubleshooting Manual and in the online help system.
