Environmental requirements

The outdoor and modular ONTs must not be installed at a location where the maximum ambient temperature exceeds 60C (140F), with no solar loading, and the minimum ambient temperature does not go below -40C (-40F).The indoor ONT must not be installed at a location where the ambient temperature range exceeds 0C (32F) to 40C (104F) with no solar loading.During operation in the supported temperature range, condensation inside the ONT caused by humidity is not an issue. To avoid condensation caused by rapid changes in temperature and humidity, Alcatel-Lucent recommends:

The door of the ONT not be opened until temperature inside and outside the enclosure has stabilized.

If the door of the ONT must be opened after a rapid change in temperature or humidity, use a dry cloth to wipe down the metal interior to prevent the risk of condensation.

When high humidity is present, installation of a cover or tent over the ONT helps prevent condensation when the door is opened.

1.1 Introduction

This document provides instructions for tasks and procedures for the 7342 ISAM FTTU Optical Network Terminals (ONTs).

1.2 How to use this document

This document uses the task-oriented practice (TOP) method. The TOP method is a documentation method that supports the installation, operations, and maintenance of telecommunications equipment and software through different layers of documentation.

TOP layersThe TOP documentation method uses the following layers:

IXL Index List NTP Non-Trouble Procedure DLP Detailed Level Procedure RTL Routine Task List RTP Routine Task Procedure TAD Trouble Analysis Data TAP Trouble Analysis Procedure TNG Training

Figure 1-1 shows the layers and major paths of the TOP documentation method.

1 Introduction


Index List (IXL)The IXL provides the master task list. The list provides information about each task, procedure, related supporting information, and the identification number of the corresponding TOP layer document (for example, DLP 500).

Non-Trouble Procedure (NTP)An NTP describes how to perform a task, such as how to accept a system after it has been installed, turn up a system for service, or maintain a system according to a maintenance plan. NTPs are made up of steps that refer to DLPs or TNGs. This approach allows users to go to the DLPs for detailed procedural and safety information and the TNGs for supporting information needed to complete the task. If users go to the referenced DLP or TNG, they must return to the NTP to continue the task.

NTPs are typically referenced from the IXL.

Detailed Level Procedure (DLP)A DLP describes how to perform a procedure, such as how to log in to the system. In addition to step-by-step information, DLPs may contain tables or illustrations that are required to perform the procedure.

DLPs can be referenced from the IXL, an NTP, a lower-level TAP, another DLP, or from a TNG.

Routine Task List (RTL)An RTL provides a listing of routine maintenance procedures. The detailed steps for each procedure listed in the RTL are provided in RTPs.

RTLs are typically referenced from the IXL.

Routine Task Procedure (RTP)An RTP describes how to perform a routine maintenance procedure.

RTPs are typically referenced from an RTL, but references can be made from the IXL if there is no RTL.

Trouble Analysis Data (TAD)A TAD contains supporting information (other than procedural steps) to be used as a trouble-clearing aid. It may be a functional schematic, text, or trouble-clearing chart.

TADs are typically referenced from a TAP.

1 Introduction


Trouble Analysis Procedure (TAP)A TAP is intended to help identify and clear trouble in the system. TAPs may be organized in levels. A high-level TAP is designed to categorize the trouble through a series of decisions and instructions. After the trouble is categorized, a lower-level TAP is referenced. This lower-level TAP addresses only the isolated topic and is structured to isolate and clear the trouble through a series of decisions and instructions without returning to the higher-level TAP. For less-experienced users (or experienced users who want more information), a TAP may provide references to a TAD, DLP, or TNG. If users go to the referenced TAD, DLP, or TNG, they need to return to the TAP to continue the procedure.

TAPs are typically referenced from the IXL or other TAPs.

Training (TNG)A TNG contains supplementary information about a task or procedure. A TNG may refer to a DLP or other document. If users go to the referenced DLP or other document, they must return to the TNG.

TNGs are typically referenced from an IXL, but references are also made from other TOP layers such as NTPs and DLPs.

Step detailsNTPs, DLPs, RTPs, and TAPs use procedural steps and decision steps.

Procedural steps provide instructions, and decision steps provide a go-to option.

Procedural steps may contain notations that refer to additional information, such as tables, figures, examples, and other TOP document layers. For example, a step in an NTP might refer to a DLP.

The key information required to complete a step is shown at the beginning of the step.

Additional information is enclosed in parentheses as shown in the following example:

Log in to the system (see DLP-500).The completion of a specific task or procedure is indicated as follows:

STOP. This procedure is complete.

2.1 About this document

This document provides optical network terminal (ONT) troubleshooting guidance for the Alcatel-Lucent 7342 ISAM FTTU GPON ONTs.

2.2 ONT functional description

A 7342 ISAM FTTU system consists of a Packet Optical Line Termination (P-OLT), an element management system (EMS), and ONTs.The P-OLT resides in the CO or CEV and performs a network-to-PON interface function. The P-OLT consists of NT and LT cards. Each LT card supports two GPON interfaces. These LT cards together with the NT cards perform the OLT function described in ITU G984.1. The P-OLT is connected by a fiber through GPON to ONT units located near the end user.

ONTs are edge devices that terminate the PON and provide voice, data, and video services to the subscriber. All ONTs use GPON technology for fiber extension from the CO.

2.3 Fault isolation summary

The primary end-to-end components involved in fault isolation, or troubleshooting, include the residential gateway (RG), the 7342 ISAM FTTU platform (P-OLT and ONT), and network or element management systems (TL1, 5526 AMS, or 5528 WAM). Faults can occur within and between any of these components.Faults are classified in three general fault categories as follows:

physical connectivity service-independent service-related

Physical connectivity

These faults involve connectivity between the network, the subscriber equipment (set top box, home computer, or VoIP phone), and the RG. Physical connectivity issues can cause faults in several ways. For example, compromised physical connectivity in the Ethernet path could cause bit error rate (BER) fault, errored frames. POTS connectivity issues could cause transmission problems or voice processing related issues. On the PON, physical connections could cause performance-related issues, such as BER errors or frame P-discards.

2 ONT overview


Bit errors between the PON and the ONT can be caused by multiple factors:

ONT, LT, or PON restarts mismatched fiber connectors, for example, UPS connected to APC dirty fiber connections; see DLP 102 bad fiber; see DLP 100 signal level too high or too low; see DLP 104 bad splitters unterminated fiber connections putting light on a fiber during installation

Finally, this type of issue could trigger RG faults, line card failures on the OLT, and Ethernet link failures between the P-OLT and the north-bound switch.

Service-independentService-independent faults can affect multiple services concurrently. These issues primarily involve the network control/management plane and the data plane, including quality of service (QoS). Service-independent issues are characterized by faults such as P-OLT/ONT provisioning and configuration errors, end-to-end signaling interruptions, and network management system communication issues.

Service-relatedService-related faults comprise a dynamic number of components, depending on the customer deployment. Service-related issues can cause faults in services, such as voice (POTS/VoIP), video (in-band or overlay), and data (high speed Internet). For example, voice service issues could include no dial tone, echo, or pops/clicks on the line. Video problems could include no reception, poor quality, or delayed channel change messages. Finally, data service-related issues could include intermittent problems accessing the Internet or poor throughput.

2.4 Analyzing faults

7342 ISAM FTTU customers have many tools available to analyze faults in their network and deployed equipment. The primary tools are software alarms that indicate equipment/facility fault conditions and equipment LEDs that indicate signal transmission or physical failure problems. Fault isolation may involve an analysis of both.

This document provides fault isolation guidance through ONT troubleshooting topics. At a high level, summary lists that provide guidance for clearing fault conditions are as follows:

For an ONT-specific list of system software alarms and possible resolutions, refer to TAP- 100 Troubleshoot ONT software alarms.

For a TCA-specific list of system software alarms and possible resolutions, refer to TAP- 101 Troubleshoot threshold crossing alerts.

For a summary of common service-related issues, refer to TAP- 102 Common fault conditions.

2 ONT overview


Detailed procedures, additional TAPS, and general training topics are also provided.

2.5 Resolving alarms

Resolve alarms that affect service before those that do not affect service.

1 Use local procedures to correct problems associated with customized alarms.2 Contact Alcatel-Lucent Support at 1-888-252-2832 (1-888-ALCATEC), or visit

the support website at www1.alcatel-lucent.com/comps/pages/carrier_support.jhtml.

3 Use the TL1 autonomous messages generated during trouble locating and additional data, such as visual or audible alarms, when available. Service states and performance monitoring information should also be considered.

4 See the 7342 ISAM FTTU TL1 Commands and Messages Reference guide for information on TL1 syntax and command response.

Note If multiple alarms are present, resolve alarms in the order in which they are listed below.

PurposeThis DLP has been intentionally removed. A more recent DLP documenting this functionality is available. See the 7342 ISAM FTTU P-OLT and ONT Fault Isolation and Troubleshooting guide for more information.


TAP 100-2 July 2007 Alcatel-Lucent 7342 ISAM FTTU ONT R04.04.10ONT Troubleshooting Guide Edition 01 3FE 51532 AAAA TCZZA



PurposeThis TAP provides the steps to isolate common fault conditions.

GeneralSeveral TL1 command sets are useful for evaluating, isolating, and clearing ONT fault conditions, including the following:

for system software-generated alarms, RTRV-ALM commands for performance monitoring, RTRV-PM commands for operation status, REPT-OPSTAT commands

System software-generated alarms (RTRV-ALM)Use the appropriate RTRV-ALM command for the following command sets to troubleshoot system software-generated alarm messages that indicate alarms for ONTs. The command sets include the following:

See TAP- 100 Troubleshoot ONT software alarms for more information.

RTRV-ALM-ALL RTRV-ALM-BRGPORT RTRV-ALM-ONT RTRV-ALM-PON RTRV-ALM-ONTPOTS RTRV-ALM-ONTCARD RTRV-ALM-ONTVOIP RTRV-ALM-ONTCESUNI

RTRV-ALM-CESPW RTRV-ALM-ONTENET RTRV-ALM-ONTVDSL RTRV-ALM-ONTHSI RTRV-ALM-ONTVIDOL RTRV-ALM-ONTMOCA RTRV-ALM-ONTL2UNI RTRV-ALM-ONTXDSL



Performance monitoring (RTRV-PM)Performance monitoring (PM) reports are recommended for debugging some common ONT fault conditions.

Some of the more helpful RTRV-PM TL1 commands used to retrieve PM threshold data for ONTs include the following:

See the 7342 ISAM FTTU Product Information Manual for general information about performance monitoring and call statistics. Specific information about ONT PMs and call statistics is located in the 7342 ISAM FTTU ONT Product Information Manual.

Note Always resolve alarms that affect service before those that do not affect service.

Note VDSL channel performance monitoring retrieved using RTRV-PM-VCHNL is currently unavailable.



Operation status monitoring (REPT-OPSTAT)Operation status reports are useful for isolating and clearing fault conditions. The following REPT-OPSTAT commands are particularly useful for ONT troubleshooting:

REPT-OPSTAT-ONT for debugging ONT general alarms REPT-OPSTAT-ONTANI for debugging ONT MOCA alarms related to optical levels REPT-OPSTAT-ONTCALLHIST for debugging ONT alarms related to call history for

a POTS line REPT-OPSTAT-ONTENET for debugging Ethernet port duplex and link status REPT-OPSTAT-ONTMOCA for debugging ONT MOCA operational alarms REPT-OPSTAT-ONTPWRSHED for debugging power shedding behavioral problems REPT-OPSTAT-PON for debugging PON facility faults related to ONTs REPT-OPSTAT-PONIGMPCHN for debugging PON/IGMP faults REPT-OPSTAT-PONIGMPCHNMEM for debugging PON/IGMP memory faults REPT-OPSTAT-PONIGMPMDL for debugging PON/IGMP faults REPT-OPSTAT-PONMCSRC for debugging PON/IGMP faults REPT-OPSTAT-PONARPENT for debugging PON/Internet Protocol (IP) faults REPT-OPSTAT-PONDHCPRELAY for debugging DHCP relay REPT-OPSTAT-ONTVIDANI for debugging video overlay REPT-OPSTAT-ONTVOIP for debugging VoIP services RTRV-OPSTAT-CESPW for debugging CES psuedowire faults

See TAP- 100 Troubleshoot ONT software alarms for more information.

ProcedureUse this procedure to isolate problems indicated by alarm reports.

1 Find the general trouble description and associated suggestions and guidance for appropriate actions using the following tables:

Table TAP 102-1 for voice scenarios Table TAP 102-2 for ENET scenarios Table TAP 102-3 for video scenarios Table TAP 102-4 for ONT installation scenarios

Note The INACT alarm is reported against the ONT for many conditions, including LOS, LOA, SF, LCD, LOA, LOAM, and DG. Note that each of these conditions trigger the INACT alarm. When an INACT alarm is raised it is buffered for a set amount of time. If multiple ONTs on the same PON raise INACT alarms as well, one PONLOS alarm is raised and the INACT alarms are dropped. You can determine the particular alarm that triggered the INACT alarm using the TL1 command REPT-OPSTAT-ONT, which reports all outstanding conditions.



Table TAP 102-1: Voice scenarios (ONTPOTS, ONTVOIP)

Trouble Possible solution

No dial tone 1) Retrieve alarms. If alarms are present, follow trouble clearing procedures for those alarms first. Common dial tone alarms include MGC communication failure, VoIP DHCP Failure, and VoIP Configuration File errors.2) If there are no alarms, but there is no dial tone, check for proper configuration of the voice subscriber in the G6 voice gateway (or Softswitch) and in the PSTN switch. Also, check the customer premises telephone sets and telephone wiring.3) Verify PBIT values in the voice service PQ profile match PBIT values in the G6 GBE address configuration. For example, if the G6 is using PBIT 7 by default and PBIT 0 for bearer, then make sure PQ profile maps PBIT 0 to the low priority queue and maps PBIT 7 to the high priority queue. NOTE: Some IP addresses cannot be used for voice services. The following IP subnets cannot be used for VoIP services: 224.0.0.0 to 239.255.255.255 (multicast) 127.0.0.0 to 127.255.255.255 (loopback) 192.168.1.0 to 192.168.1.255 192.168.2.0 to 192.168.2.255 192.168.3.0 to 192.168.3.255 192.168.4.0 to 192.168.4.255

Slow or delayed dial tone 1) Run a call trace using G6. Look for repeated/retransmitted packets that would indicate packet loss in data network. 2) Ensure that no traces have been enabled on the ONT console port by support personnel. Enabled VoIP traces on the ONT console can cause delayed dial tone.3) Check for packet loss and jitter using the TL1 command REPT-OPSTAT-ONTCALLHIST. (Ensure that the CALLHIST parameter setting is enabled in the ONTPOTS port configuration before using this command.)

Echo Check jitter buffer settings in G6 for retrieve line, line profile, CPE. If the nominal jitter buffer size is too big, the delay can be too high, which increases the effects of echo.

Pops and clicks Check jitter buffer settings in G6 (e.g., retrieve line, line profile, CPE). If the maximum jitter buffer setting is too small, jitter in the packet stream can cause pops and clicks on the line.

MLT test fails Perform an MLT test using DGN-ONTPOTS. If the MLT test fails, determine the type of fault in the CPE (i.e., hazardous potential, foreign EMF, resistive faults, receiver off-hook, or ringer) based on the response text. Diagnose the failure indicated.

Phone does not ring (DC offset for some phones)

1) Verify that the VoIP configuration file error alarm is not present. Also verify that VoIP service is configured in the proper mode (e.g., ANSIH248 for operation with G6; SSH248 otherwise). 2) Verify that G6 provisioning includes the following settings: CPE PT = 97 bcastrestricted = enable

3) Ensure that the value of the AGEING parameter in the RTRV-PONVLANSYS and SET-PONVLANSYS is larger than the value of the Inactivity Timer in the G6 show services h248 bbi setting.

Call drop Verify that BW profiles in the OLT are applied to VoIP service. NOTE: Minimum BW values are 128 kb/s CIR/EIR per POTS line with DT set equal to 8.

Table TAP 102-2: ENET scenarios (ONTENET)

Caller ID does not work Perform external ethereal captures of ONT POTS traffic to look for caller ID messaging. If there is no messaging, the problem could be related to the Class 5 SW timer. Make sure this timer is set appropriately for caller ID.NOTE: For loop emulation mode, this solution would not be effective; however, this solution could be effective with Softswitch or G6.

Dial tone on one line but not on other lines

Verify the subscriber configuration in the PSTN switch, G6 voice gateway/Softswitch, and the 7342 ISAM FTTU OLT.

Modem/fax issues 1) Make sure there are no PON BER errors using the REPT-OPSTAT-PON command.2) Use the DGN-ONTPOTS command to diagnose the POTS line and make sure there are no faults on the POTS line in question.


LINK LED off or intermittent link 1) Verify the physical connection. On this side, that means to check the ONT connectors to ensure they are not damaged, the cable connections or cable type (checking for wrong cable), or the gateway (RG). On the other side, the equipment state must be verified per local practice. Most likely, the RG for the ONT (gateway) or the ENET could be down. 2) Use the TL1 command RTRV ONTENET to check the state related to this ONT and the ONT connection. You can reset the service state from OOS-MA to IS. To correct the physical connection problem, replace the physical interface, the RG, or the cable.NOTE: The only distinction between the LINK LED off and the intermittent link condition is that if the Link is off, it could be OOS but the intermittent link would always be IS.

Throughput problems (slow, none, or too much)

All three throughput problems have the same solution. It is a limited solution because PM counters are not supported in this release, meaning no measurement or indicators are available to provide assistance clearing the alarms. Sometimes customers have sensing equipment, but the only practical solution is to perform the following:(1) Verify that the service provisioning is correct according to service level.(2) If it is correct, contact Alcatel-Lucent Customer technical support for additional help.

Setup (10/100/1000 Mb/s, half/full duplex, autosensing)

When established using the ENT ONTENET command, the speed stays the same. However, sometimes the link goes up and down. For the outdoor ONT, problems will be indicated by the Mode LED. If there is a trouble indication, use the TL1 command REPT OPSTAT ONTENET to check settings for auto-negotiation and the 10/100/1000 Mb/s setting.

Cannot enter ONTENET Make sure both the ONTCARD as well as the ONT are provisioned. Also make sure you are not trying to provision a second port on a one-port ONT.

Cannot delete LAN provisioning Like any equipment or facility carrying traffic (IS), the LAN ENET must be put OOS in order to delete it.

No video or bad video signal Trouble related to no video and bad video signal requires the same troubleshooting steps.There could be several reasons for this condition, but the most likely are that the maximum bandwidth is exceeded or the maximum number of groups are exceeded. 1) For the maximum bandwidth setting, you must have adequate bandwidth reserved. The default setting is 0, so this value must be set instead of accepting the default.2) For the maximum number of groups exceeded, reset the cap max groups setting high enough.Note the following troubleshooting tips:...Make sure you have provisioned the correct amount of bandwidth...Look for dropping packets...Look for CRC errors...Look for total fail joins, all fails...Check max host setting and max stream setting...Look for peak rates setting (modular ONT only).

Channel change problems Channel change problems might be related to incorrect bandwidth provisioning, the system dropping packets, or CRC errors. However, the problems are typically message rate problems. Check the ONT rate shaping counter. (Modular ONT only.)


LEDs do not light properly when the ONT is installed

See TNG- 100 ONT LEDs in this document to determine the source of the problem.

A NEW ONT alarm is expected, but no NEW ONT alarm displays

This could be caused if the new ONT equipment is not functioning properly or if the fiber connected to the ONT is bad. Check the fiber for a good signal. If the problem persists, replace the ONT.

ONT alarms are raised at the CO concurrent with installation

See TAP- 100 Troubleshoot ONT software alarms in this document.

PON physical connection Check the fiber at both ends.

Power/UPS connection See TAP- 107 Restore ONT power and TAP- 103 Equipment LED problems in this document.
