Cause why "STND" is displayed in the NE Explorer for the OSN 8800 TN54TOA board


It is a reserved design, because there are boards in compatible mode (COMP) and boards in standard mode (STND).

Impact of changing the NE ID of OSN 8800
The following functions will be affected if the NE ID is changed for WDM devices: the logical fiber connections (FM), automatic optical power adjustment (OPA), intelligent power adjustment (IPA), automatic level control (ALC), automatic power equilibrium (APE), wavelength locking, optical port protection, OWSP protection, OD, and OD V2.

Cause why the STG board is mandatory for the OSN 8800 but optional for the OSN 6800
The OSN 8800 of version V100R002 or later is a synchronous system, requiring that all service boards and cross-connect boards are synchronized (with the same frequencies and aligned frame headers). Therefore, a unique reference clock signal and a unique frame header are required. To meet this requirement, each service board outputs services according to the clock signal and frame header of a clock board. Therefore, the STG board is mandatory for the OSN 8800 of version V100R002 or later. If no STG board is configured, centralized service scheduling cannot be achieved. The OSN 6800 is an asynchronous system and does not require a unique reference clock or unique frame header. Therefore, no STG board needs to be configured for the OSN 6800.

Cause why OSN 6800 NEs report license-related alarms
Question: A customer provides feedback that all system control boards of 48 OSN 6800 NEs report the SYSTEM_DEF_RUNNING alarm one day. One of the NEs also reports the VERIFY_LCS_ERROR alarm. Analysis: 1. A dedicated ASON license file must be loaded to an OSN 6800 NE to enable ASON for the NE. 2. The OSN 6800 NE periodically checks whether the license has been loaded on the system control board. If the ASON license has not been loaded, the SYSTEM_DEF_RUNNING alarm is reported. 3. If the ASON license has been loaded but is about to expire, the NE reports the LICENSE_GOINGTO_EXPIRT alarm. 4. If an incorrect ASON license has been loaded, the NE reports both the SYSTEM_DEF_RUNNING and VERIFY_LCS_ERROR alarms. Root cause: None Answer: 1. Because ASON has not been enabled for the NEs, directly suppress the alarm. If ASON is required later, load a correct license file. 2. Run the license-show-file command to query license information. Suggestion and conclusion: When ASON is not enabled, you are advised to set license-related alarms to be not monitored to avoid customer misunderstanding.

Whether the TDX board on the OSN 8800 can be interconnected with the SL64 board on an NG SDH NE
Yes, the two boards can be interconnected through STM-64 optical ports.

Cause why no jumper or DIP switch can be found on the AUX board of the OSN 8800
No jumper or DIP switch is available on the TN51AUX board on the OSN 8800. If master and slave subracks need to be configured, you can configure subrack IDs using EFI1 boards.
