The STG board is mainly used to lock the reference clock source and provide signals and frame signals to the system.
For detailed functions and features, refer to Table 1.
Function and Feature | Description |
---|---|
Basic function |
|
Active/standby switching function | The STG board uses a 1+1 hot backup scheme. The two STGs serve as
mutual backups. When both of them are normal, one of them functions
as the active board, and the other functions as the standby board.
Service boards select the clock source according to the status of
the two STGs. When the active STG is faulty, an active/standby
switching occurs. Then, the standby STG becomes active, and the
services boards select the clock from the current active STG
according to the status of the two STGs. NOTE: The TN52STG and TN54STG boards can back up each other. That is, a TN52STG board and a TN54STG board can work in 1+1 hot backup mode. |
Clock source selection function | Traces the external clock source, service clock source, or local clock source, to provide the synchronization clock source for itself and the system. |
Time synchronization function | Synchronizes the time of an NE with the time of the upstream NE. |
Specifications include dimensions, weight, and power consumption.
