Release notification

This document covers theMetropolis® AM and Metropolis® AMS releases 1.0 through 7.1.

Compared to the provided descriptions some of the legacy releases may vary due to the feature upgrades.

Overview EMC/ESD Safety

The EMC/ESD boundary has been defined at Rack/Subrack level. The principle is based on the “Faraday Cage” theory. If there are doors, thenthe doors must be closed. With every rack/subrack an ESD (electrostatic discharge) earth socket and an ESD sticker are supplied. On the Rackframe ETSI an ESD bonding point for an ESD wrist strap is present. It is mounted in a way that it’s always accessible for installation, normaloperation and maintenance activity.

Wrist Strap

The wrist strap must be worn when opening the Subrack doors.

Electrostatic Sensitive Devices

The equipment described in this guide contains static sensitive devices. Electrostatic Discharge Precautions should be taken when operating orworking on this equipment.

Special handling precautions apply whenever installing or removing parts of the equipment include:

• Leaving components or equipment in original packaging until required for use.

• Removing plug-in units with previously discharged hands (e.g. using grounded wrist straps connected to the ESD Bonding Point on the Cabinet).

• Returning items for repair in suitable antistatic packaging.

About this information productAbout this information product

Purpose

The purpose of this Alarm Messages and Trouble Clearing Guide (AMTCG) is toprovide the maintenance personnel with all information necessary to solve the alarmsin a specific Network Element (NE), using the Integrated Transport Management-Subnetwork Controller (ITM-SC). The Alarm Messages and Trouble Clearing Guide(AMTCG)) is a network oriented manual and will be shipped to all sites where anITM-SC is available. The philosophy behind the maintenance of Network Elementswithin a network is that the network is already installed, configured and service hasbeen provided to the network after first installation.

The alarms that can be reported byMetropolis® AM and Metropolis® AMS systemscan be divided into these alarm categories:

• EnvironmentEnvironment alarms are caused by defects detected in external devices which canbe monitored.

• EquipmentEquipment alarms are caused by hardware defects.

• Processing errorProcessing alarms are caused by inconsistencies in the internal data processing.

• Quality of service (performance monitoring)Quality of service alarms are caused by threshold crossings of performancemonitoring counters.

• TransmissionTransmission alarms are caused by defects detected in the transmission signal.

Alarm severity

The “Alarm severity (default setting)” entry in the alarm overview table indicates thefactory settings of the corresponding alarm’s severity.

Each alarm can be assigned one of the following severities:

Alarm severity Meaning

Prompt Prompt maintenance alarm:

Urgent alarm that requires immediate (prompt) maintenanceaction.

Deferred Deferred maintenance alarm:

Non-urgent alarm that requires deferred maintenance action.

Information Informational alarm.

Reporting state

The “Reporting state (default setting)” entry in the alarm overview table indicates thefactory settings of the corresponding alarm’s reporting state, i.e. whether an alarm isreported towards the management systems or not.

365-312-803R7.1Issue 1, November 2006

Each alarm can be assigned one of the following reporting states:

Alarm severity Meaning

Reported The alarm - when raised - will be reported towards themanagement systems (ITM-SC and ITM-CIT), and displayedon the graphical user interfaces.

Not Reported The alarm - when raised - willnot be reported.

Please note that changing the alarm reporting state does not affect the display ofcurrently present and history alarms. Especially the display of already present alarmscannot be removed if their reporting state is changed from “Reported” to “NotReported”.

Local indications

Local indications are indications directly at the network element, typically vialight-emitting diodes (LEDs), especially via the red fault LED on the unit.

Please note that the local indications via the red fault LED arecontrolled by defects,not alarms.

Operation modes...................................................................................................................................................................................................................................

Slot modes

The slots of aMetropolis® AM and Metropolis® AMS system can be occupied by a“unit”. A unit is either a main unit or a tributary unit. Usually, a unit occupies a singleslot. However, some tributary units (i.e. legacy option boards, mounted on an adaptercard) occupy two slots.

These slot modes exist:

ASSIGNED The slot is configured to contain a unit of a specified type. If a unit of acompatible type1 is present in the slot, then the unit provides service, exceptfor transmission ports. Transmission ports are controlled by the port modeconfiguration, see“Monitoring modes” (p. 1-13).

Assigned slots are monitored for equipment defects, and corresponding alarmmessages will be reported.

AUTO The slot may still be empty, but ispre-configuredto contain a unit of aspecific type.

This slot mode corresponds to the UNASSIGNED mode as long as no unit ispresent. As soon as the presence of a compatible unit is detected the slotmode is automatically changed to ASSIGNED. Note that if a unit of anincompatible type is detected, a “Wrong Unit Present” alarm (UNITcWUP)will be reported.

UNASSIGNED The slot is configured to be empty. If a unit is present in an UNASSIGNEDslot then the unit doesnot provide service; if there are ports on the unit,then incoming signals will not be processed, and will not be monitored fordefects.

No alarms will be generated in case of a fault or error condition on a unit inan UNASSIGNED slot; only its presence will be signaled as a faultcondition (“Unit present in unassigned slot”, UPUS).

Notes:

1. A compatible unit is a unit which is permissible for the respective slot. Please refer to the Metropolis®

AM andMetropolis® AMS Applications and Planning Guidefor compatibility information.

Monitoring modes

Monitoring modes are applicable to physical ports, trail termination points and nonintrusive monitoring (NIM) points. Monitoring modes can be provisioned for each typeof physical port or termination point (TP) individually.

The setting of the monitoring mode determines whether an incoming signal will beprocessed, including alarm supervision and performance monitoring.

These monitoring modes exist:

Alarm messages

...................................................................................................................................................................................................................................365-312-803R7.1Issue 1, November 2006


1-13

“Monitored” (MON) Monitoring is enabled. The port or termination point provides service, andthe incoming port or termination point signal is monitored for defects. Thismeans that receive and transmit side signals are processed according to theprovisioning of the port or termination point, including alarm supervisionand performance monitoring.

“Automatic” (AUTO) A port or termination point can be put into this mode when the signalsource in the remote system is not (yet) operational.

Monitoring is disabled as long as no receive- and transmit-side signals areapplied. However, the monitoring mode is automatically switched tomonitored as soon as a signal is continuously applied.

“Not monitored”(NMON)

A port or termination point can be put into this mode when it is not used.

Monitoring is disabled, the incoming port or termination point signal isnotmonitored for defects.

Port monitoring mode

The monitoring mode of a physical port can be set for each port individually to:

• “Automatic” (AUTO),

• “Monitored” (MON), or

• “Not monitored” (NMON).

RS and MS termination point monitoring mode

Regenerator Section (RS) and Multiplex Section (MS) termination points have thesame monitoring modes as their associated physical interface (= physical port).

VC trail termination point monitoring mode

The monitoring mode of a VC trail termination point (TTP) can be set for each TTPindividually to:



VC-Xv path termination point monitoring mode

The monitoring mode of a VC-Xv trail termination point (TTP) can be set for eachTTP individually to:



P11s and P12s path termination point monitoring mode

The monitoring mode of a P11s or P12s trail termination point (TTP) can be set foreach TTP individually to:

Alarm category Quality of service (performance monitoring)


Information


Not Reported


Cause A frame slip/skip event indicates a synchronisation difference between the SDHclock of the netwerk element that performs the re-timing and the networkelement that generated the E1 (2 Mbit/s) signal, usually a voice switch or 64-kbit/s level cross-connect.

Actions Check the synchronisation trails to both theMetropolis® AM and Metropolis®

AMS and the network element that generated the E1 (2 Mbit/s) signal.

These two network elements should have their respective clocks traced back tothe same synchronization source when theMetropolis® AM and Metropolis®

Failed segment in SHDSL span...................................................................................................................................................................................................................................

Alarm identifier SRUcSEGD

Information An SHDSL segment has failed.



Prompt


Reported


Cause In one of the SRUs of the SHDSL span, a LOSW condition has been detected.As a consequent action, the “segd” overhead bit has been set as an indicationthat the SHDSL segment in the downstream direction of the SRU has failed.

Actions Locate the SRU where the LOSW condition is detected at the customer-sideSHDSL port. The SHDSL segment “behind” that SRU has failed (see theexample subsequent to this table).

For the failed SHDSL segment:

• Verify the correct routing of interconnecting cables.

• Verify that the connectors are properly connected at the local and remoteend of the SHDSL segment.

• Verify that the receiver at the local end of the SHDSL segment (i.e. at theSRU where the LOSW condition has been detected) functions properly.

• Verify that the transmitter at the remote end of the SHDSL segment (i.e. atthe next attached SHDSL device in the downstream direction) functionsproperly.

Note(s) The SHDSL segment between the SRU with the highest address that stillresponds to alarm polling (and reports a LOSW alarm on its customer-sideSHDSL port) and the next SHDSL device is failed. All managementconnectivity to the SHDSL device downstream from the failed segment andother SHDSL devices behind it, is lost. This means that transmission (andhence management communication) is no longer possible with the NTU andpossibly with an SRU.

Example

This example illustrates the fault localization in case of a failed segment in an SHDSLspan:

Loss of Q2-communications...................................................................................................................................................................................................................................

Alarm identifier MLQ2

Information Communication between the network element and the ITM-SC is lost.



Information


Reported

Local indications

Cause The communication path between ITM-SC and the reporting network elementis out of order. To pinpoint the reason one has to look into how thecommunication path has been or should be setup and if there are alarmsreported on intermediary network elements in the path between ITM-SC andreporting network element. One would have to look for alarms such asLoss of Q2-communication (MLQ2), Q-LANtermination loopback failed (LANcTRM), transmission failures or unitfailures reported within the complete communication path between networkelement and ITM-SC. If there are none then the DCC path settings have to bechecked between the network element and the first next associated networkelement in the communication path.

Actions If the red fault LED on the System Controller is flashing, then the associatedalarm isQ-LAN termination loopback failed (LANcTRM), and youshould check that alarm for cause and action.

If red fault LED on the System Controller is off:

• Check for relevant alarms on network elements in the communication pathtowards the management system, and repair those first.

• If there are a few SCs reporting an MLQ2 alarm and they are all connectedto one (single) Q-LAN then pull the System Controllers out one by onesince one of them may have a LAN device failure. Pulling an SC does(should) not break the Q-LAN.

• Connect the ITM-CIT to the reporting network element and check theAREA (Login → Area). The nearest, in the path towards the ITM-SC,missing network element in the area list is most probably also the networkelement where the problem cause resides.

• Check the DCC settings in the communication path.

• If it is not possible to get association with the network element (afterinitial installation) then the network element state may be “Isolated”. Makelocal contact with the ITM-CIT to the network element involved and checkand confirm the DCN settings: Management→ Overlay Comms Network→ DCN → Edit → OK.

• It is also possible that the SEEPROM is defective, or the contents iscorrupt.

As a means to ensure that an NTU is communicating with a single LTU overall its interfaces, the LTU sends a “signature” as part of the startup procedure,after an attached SDSL-NT10ETH modem is detected.

The signature is sent in a special EOC-ext. message before any configurationdata are transmitted. In case the authentication is unsuccessful (for example, ifan NTU is connected with multiple LTUs; cf.“Typical wiring errors”(p. 1-152)– wiring error type III), then the NTU returns an error code (0xB1)to the LTU. If, after 3 retries, the authentication still remains unsuccessful,then anSHDSLNetwork Termination Unit authentication error alarm is reported.

SHDSL Network Termination Unit configuration commandincomplete...................................................................................................................................................................................................................................

Alarm identifier NTUcCNC

Information A configuration command has possibly not been executed.



Deferred


Reported


Cause An invalid response on a configuration command has been received from theNTU modem.

Actions Verify that the correct software image is running on the NTU. If this isnot thecase, then download a suitable software image to the NTU, and perform a resetin order to activate this software image.

If a suitable software image is running on the NTU, then reset the NTU, orinitiate a rediscovery of the SHDSL link.

Note(s) The detection of an NTUcCNC condition has no direct consequences for theoperation, the management of the remaining parameters continues as before.

EOC communication failures

There is no mechanism at the EOC link layer to guarantee delivery of a message,except that each message requires at least one prescribed reply message. Reception ofthe expected response(s) can be interpreted as a successful completion of anEOC/EOC-ext. message exchange.

However, in case the expected response(s) are not received, two categories of EOCcommunication failures can be differentiated:

• A missing response (no response/confirmation at all, after 3 retries, while theSHDSL line itself is operational) indicates a complete break-down of thecommunication, leading to an “Embedded operations channel failure” (EOCF)alarm.

• An invalid response suggests that a configuration command has not been executed.As a consequence, the configuration stored in the management information base(MIB) on the LTU and the actual configuration of the connected SHDSL devicemight differ. An invalid response leads to a “Configuration command incomplete”(CNC) alarm.

Geographic Redundancy (GR)Allows protection of management for a network element by assigning the networkelement to two ITM-SCs. The first primary ITM-SC usually manages the NetworkElement and is now in the protected domain. If the primary ITM-SC or the link betweenthe network element and the primary ITM-SC fails, the secondary ITM-SC willautomatically take over management of the network element and is now in the protectingdomain. The two ITM-SCs are connected by a peer to peer link, which they use to passGeographic Redundancy management information to each other.

IS-IS RoutingThe network elements in a management network route packets (data) between each otherusing an IS-IS level protocol. The size of a network that is running IS-IS Level 1 islimited, and therefore certain mechanisms are employed to facilitate the management oflarger networks. For STATIC ROUTING, it is possible to disable the protocol over theLAN connections and thereby effectively cause the management network to bepartitioned into separate IS-IS Level 1 areas. In order for the ITM-SC to communicatewith a specific network element in one of these areas, the ITM-SC must identify theGateway network elementthrough which this specific network element is connected tothe LAN. All packets to this specific network element are routed directly to the Gatewaynetwork element by the ITM-SC, before being re-routed (if necessary) within the Level1 area. For DYNAMIC ROUTING an IS-IS Level 2 routing protocol is used that allowsa number of Level 1 areas to interwork. The network elements that connect an IS-IS areato another area are set to run the IS-IS Level 2 protocol within the network element andon the connection to other network elements. Packets can now be routed between IS-ISareas and the ITM-SC does not have to identify the Gateway network elements.

TemplateA collection of parameters that define a specific network element configuration. Atemplate gives the user the opportunity to configure parameters in a network elementwith a single operation. The template is re-usable and allow the user to configure theparameters in many Network Elements in the same way. A set of default templates isprovided, and the user can create new templates and edit or delete user-created ones.Note that a template is always associated with one specific network element type andcan not be used for other network element types.
