10G link service was abnormal of OSN 8800

Joshuakoo

One 10G link service was abnormal of Huawei WDM OSN 8800. Getting lambda down due to which multiple POI’s, voice and enterprise services were down.

J0 trace test done on TQX board of Huawei side.

As per the analysis done and J0 test on TQX board on Huawei side, found J0 Alcatel did not received from alcatel MUX.

J0 sent from SLQ64 board of Huawei 8801 MUX slot 36-2 did not match.

Wrong connectivity observed at site.

The root cause of this issue is fiber on Huawei 8802 was wrongly connected to Huawei 8801 port 36-2 instead of slot5-4 on ALCATEL MUX.

1.   Short Term: Optimize the trail to other path and lock the ASON rerouting functionality.

2.   Long Term: It was observed that the fiber was wrongly connected to Huawei Mux 8801 slot 36-2 which should have been connected to ALCATEL MUX on slot5-4. After connecting fiber to correct port on ALCATEL side, switchover testing done and found services working fine on Huawei optix OSN 8800.

Verification of J0 trace on important service and newly integrated services for identifying the correct fiber connection.
