Fig. 21 P+E

Due to the attribute of the circuitry of P+E interface, it is harmful to plug and unplug the UTP cable to and from the P+E interface very frequently with short intervals. It is strongly suggested to leave at least 5 seconds between plugging and unplugging (and vice-versa) the cable.

When using P+E ports of IDU to feed DC power to ODUs, please keep the P+E cable length and the DC input voltage to IDU within the “safe border” reported in Fig. 22 and the overall current to all the ODUs should be lower than 6A.

WARNING The P+E solution is not compatible with Power over Ethernet (PoE) defined by IEEE 802.3af and 802.3at since P+E intends to provide higher power (watts) than that provided by the two standards. Thus, it is harmful to connect FPH800 P+E interfaces to other devices than NSN’s FlexiPacket ODU’s.

WARNING It is forbidden to connect other P+E ports (for example, the P+E ports of the external Power Injector) to the P+E ports of FPH800 whether the P+E function of FPH800 is disabled or enabled.

3.1.1 E-Line service

FM200/HUB 800 supports both E-Line service and E-LAN service.

In E-Line service, traffic from any configurable port can go to any other configurable port.

In Fig. 24, packets received from ingress port, are parsed and processed, e.g., policing, countering, editing etc.

The selection of egress port is not based on L2 bridging, but it's based on rule definition.

Fig. 24 E-Line illustration


FT48927EN03GLA0


3.1.2 E-LAN service

E-LAN service is based on L2 bridging by learning the source MAC address and matching the destination MAC address. The packet destination MAC address + VLAN ID determines its egress port, see the illustration in Fig. 25.

E-LAN service is a multipoint-to-multipoint service that can be used for both management plane (management E-LAN) and for data plane. For example in 4G networks, packets received from a BTS can be directed either to core network or a neighbor BTS, the forwarding decision is based on destination MAC address matching.

Fig. 25 E-LAN service illustration

3.1.3 UNI port shutdown on service failure

UNI port is switched off in case of loss of E2E connectivity.

This feature is only applicable when there is only one E-line service on a UNI.

When a UNI has multiple E-Line services or E-LAN service on it, this feature cannot be applied to this UNI.

It's used to fast forward the loss of connectivity (e.g. due to microwave link propagation outages, or equipment failure) to connected device.

Fig. 43 Synchronization on FlexiPacket HUB

The FlexiPacket FM200/ HUB 800 system can operate in two clock modes as:

normal mode

SSM (Synchronization Status Message) mode

In normal mode, if one E1 or one Ethernet interface is selected as synchronization source, when the source fails the system goes to internal source (holdover or freerun state).

While two synchronization interfaces are selected, one as primary source and the other as secondary, when the primary source is not available, the system automatically uses the secondary one.

Once the primary source is recovered, the system comes back to the primary source if the revertive mode is set, or stays on the secondary source if the non-revertive mode is configured.

In SSM mode, the system selects the best synchronization source based on following criteria stated in the SSM message received:

signal fail

signal received QL (Quality Level)

priority

External commands


FT48927EN03GLA0


3.1.6.1 Synchronization states

If using internal source, only one synchronization state is foreseen: freerun.

If using external source, the following states are foreseen:

Freerun: this is the state selected after startup. The system will keep on working in this state if there is no valid source available.

Locked: this is the state selected after a qualified reference source is available at the selected interface and no synchronization alarms are present.

Holdover: this is the state selected when the reference source is no longer qualified due to some problems.

3.1.6.2 TDM synchronization interface

Two E1/T1 interfaces can be selected as TDM synchronization output interface.

The E1/T1 interface selected as TDM synchronization output interface carries a locally generated E1/T1 with pseudorandom payload in case of no synchronization alarms; vice versa it carries full Alarm Indication Signal (AIS) in case of synchronization alarms exist.

WARNING The E1/T1 interface selected as TDM synchronization output interface is not bounded to a TDMoP EVC and does not carry usable traffic.

An E1/T1 port can be used as TDM synchronization input interface. The system detects alarms related to the TDM synchronization input interface as in the following:

LOS (local alarm, the traceability to PRS is lost)

AIS (remote alarm)

structured E1/T1 with pseudorandom payload

3.1.7 Link Layer Discovery Protocol

LLDP is supported in FM200/ HUB 800 R2.0/2.0EP1 to advertise the system key capabilities on the Ethernet LAN and also learn the key capabilities of other systems on the same Ethernet LAN.

Information like system name and description, IP management address, etc., can be sent or received as LLDPDU (LLDP Data Unit) for every station to know their neighbors.

LLDP frames are sent at a fixed rate on each port of every station and no acknowledgement is expected from the receiver.

It is so-called one way connectionless data link layer protocol which runs on MAC layer.

LLDP allows the NMS to build the physical topology of the network under its supervision.

The NMS can only get a complete picture of the controlled network when all the NEs support LLDP.

WARNING For the detailed information of LLDP, please refer to IEEE 802.1 ABTM-2005.


FT48927EN03GLA0


3.1.8 Link Aggregation Groups (LAG)

Link Aggregation grouping is performed according to the IEEE802.3 clause 43 standard.

Link Aggregation allows multiple links to be aggregated together to form a Link Aggregation Group (LAG) as reported in Fig. 45.

A MAC Client treats the LAG as if it were a single logical link.

For Bridge functionality (i.e. VLAN, STP, etc.), the LAG is considered as a single bridge port.

A LAG operates in CET mode and is supported on UNI ports.

The LAG consists of N parallel, full-duplex, point-to-point links operating at the same speed between a pair of systems.

3.1.9 Spanning Tree Protocol

STP (Spanning Tree protocol) is supported in FlexiPacket FM200/ HUB 800 to provide a loop-free redundant network topology.

Besides basic STP configuration, RSTP (Rapid Spanning Tree Protocol) and MSTP (Multiple Spanning Tree Protocol) are supported.

RSTP(IEEE 802.1w) supersedes the basic STP (IEEE 802.1D).It provides rapid reconfiguration of the spanning tree active topology in case of physical network changes with reduced port states as forwarding, learning, and discarding only.

MSTP (IEEE 802.1) allows frames assigned to different VLANs to follow separate paths, each based on an independent MSTI (Multiple Spanning Tree Instance), within MST (Multiple Spanning Tree) regions composed of LANs and MST bridges. That is to say each VID is mapped with a MSTI.

WARNING FlexiPacket FM200 R2.0 supports up to 8 MSTI instances

WARNING FlexiPacket HUB 800 R2.0 supports up to 16 MSTI instances

3.1.10 Web-based LCT management

Through an embedded LCT program in FPFM200/HUB800, the user can access the system through the network and launch the LCT program to monitor, administer, and configure the system remotely.

All the parameters are divided into different groups, such as Hardware, Service, Licensing, etc.

WARNING For detailed information, please refer to Operate and Maintain chapter.


FT48927EN03GLA0


3.1.12.4 Account log

FlexiPacket FM200 HUB800 R2.0/2.0 EP1 embedded software stores a list of records (up to 120 records) regarding log actions (Login or Logout) performed by users.

All successful log actions will be recorded.

Each record includes the following information fields:

IP address of the user

Authentication name or community in case of SNMPv2c

Protocol type

Log action type (login, logout, password)

Date and time of the log action

Once an alarm is triggered, it needs to be downloaded and cleared from EMS.

Then NE clears alarm.

Following is the procedure for the alarm and log file:

NE sends the alarm to EMS

Download log file from NE and clears the log file manually

NE clears alarm
