Step 3

If the value is within the range of the low receive power threshold, physically verify, by using a standard power meter that the optical input power overcomes the expected power threshold. Ensure that a proper threshold has been provisioned for the receive value. If an incorrect threshold has been set, adjust it to a value within the allowed limits.

Step 4

Verify that the Trunk-Rx port is cabled correctly, and clean the fiber connecting the faulty TXP/MXP to the drop port of the DWDM card.

Step 5

Determine whether a bulk attenuator is present and if so, verify that a proper fixed attenuation value has been used.

Step 6

Using a test set, check the optical power value of the drop port of the DWDM card connected to the faulty TXP/MXP. If the read value is different (+1 dBm or 1 dBm) from the ANS setpoint for Padd&drop-Drop power, move to next step.

Step 7

Look for any alarm reported by the DWDM cards belonging to the OCHNC circuit whose destination is the faulty TXP/MXP and first troubleshoot that alarm. Possible alarm related include: amplifier Gain alarms, Automatic Power Control (APC) alarms, and LOS-P alarms on the Add or Drop ports belonging to the OCHNC circuit.

Logical Objects: TRUNK

An Alarm Indication Signal (AIS) signal communicates to the receiving node when the transmit node does not send a valid signal. AIS is not an error. The OTUK-AIS alarm is raised by the receiving node on each input when it detects the AIS instead of a real signal.

OTUK-AIS is a generic AIS signal with a repeating AIS PN-11 sequence. This pattern is inserted by the card in the ITU-T G.709 frame (Trunk) when a faulty condition is present on the client side.

OTUK-BDI Alarm

Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)

Logical Objects: TRUNK

The Optical Transport Unit Backward Defect Indication (OTUK BDI) alarm is raised when there is a path termination error in the upstream data. This error is read as a BDI bit in the path monitoring area of the digital wrapper overhead.

Clear the OTUK-BDI Alarm

Procedure

Step 1

At the near-end node, use site practices to clean trunk transmitting fiber toward the far-end node and the client receiving fiber.

Step 2

At the far-end node, determine whether any OTUK-AIS condition, is present on the Trunk-RX. If so, the root cause to be investigated is the Trunk-TX side on the near-end card (the one alarmed for OTUK-BDI) because that is the section where the AIS bit is inserted.

Step 3

If there is no OTUK-AIS at the far-end node, continue to investigate performances of the Trunk-Rx: Look for other OTU-related alarms, such as the OTUK-LOF condition or OTUK-SD condition at the far-end Trunk-RX. If either is present, resolve the condition using the appropriate procedure in this chapter.

If the alarm does not get cleared, you need to report a Service-Affecting (SA) problem.

SQUELCHED Alarm

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Objects: GE, CLIENT

The client signal squelched condition is raised by the NCS 1002 in the following situations:

  • Laser-squelch is configured under the client controller.


    Note

    Laser-squelch is supported only on QSFP+, QSFP28 LR4, and QSFP28 CWDM4 pluggables.

  • Laser-squelching occurs on a QSFP pluggable when all the four lanes operating in the 10 GE client mode are turned off after the upstream receive facility has experienced a loss of signal (such as optical LOS, LOF).

  • A MXP or TXP client facility detects that an upstream receive facility has experienced a loss of signal (such as optical LOS, LOF). In response, the client facility transmit is turned off (SQUELCHED). The upstream receive facility is the trunk receive on the same slice as the client.

  • The client will squelch if the upstream trunk receive (on the trunk port carrying the client payload) experiences a LOS, or LOF (TRUNK) alarm.

  • The client will squelch if any one of trunk ports receive LOS, or LOF. In this case, the client port is mapped to two trunk ports. For example, the HundredGigECtrlr 0/0/0/9 is mapped to the CoherentDSP0/0/0/12 and the CoherentDSP0/0/0/13 for a 10 GE to 100 GE hw-module config.

The local client raises a SQUELCHED condition if the local trunk raises one of the following alarms:

Far-end Laser Squelch

NCS 1002 supports far-end laser squelch. This feature relays the following:

  • Client input signal to the far-end client output signal, especially faults.

  • Near-end client-side faults such as SIGOSS, SYNCLOSS, HIBER, and LF to the far-end.

    If a near-end QSFP has a fault on its RX side, the far-end QSFP laser is turned off.

The SQUELCHED alarm is raised on the far-end NCS 1002 if laser-squelch is configured on the far-end NCS 1002 and a fault on the near-end NCS 1002 is observed on the client RX side.


Note

Far-end client laser squelch does not work on headless events such as a reload, CPU OIR, or an mxp_driver restart.

Clear the SQUELCHED Alarm

Procedure

Determine whether the associated NCS 1002 trunk port reports an LOF or LOS alarm (for the client trunk). If it does, turn to the relevant section in this chapter and complete the troubleshooting procedure.

TEMPERATURE Alarm
