A new OSN 6800 is deployed. The TQS and NS2 are used to configure ODU1 SNCP. After services are configured, SNCP switching fails.
NEs A-B-C-D-E-A form a 10 Gbit/s WDM ring network. All NEs are OADM sites.
The services in a wavelength are activated between NE A and NE B by using 192.1 THz. The NS2 in slot 11 is active and that in slot 12 is standby on NE B. The TQS in slot 1 is a tributary board.
After services are configured, the meter tests that NE B is normal. Remove the IN fiber on the NS2 in slot 11 on NE B. The meter shows LOS and the NS2 in slot 12 reports an ODU1_PM-BDI alarm. The corresponding NS2 on NE A reports an ODU1_PM-OCI alarm.
The NE software is 22.214.171.124 and T2000 version is V2R4C01B024.
