Huawei STG TN13STG 03023HCL OSN 8800 OSN 6800
Product Description:
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. The TN13STG and TN11STG (or TN12STG) boards can back up each other. That is, a TN13STG board and a TN11STG (or TN12STG) board can work in 1+1 hot backup mode. The TNK3STG and TNK2STG boards can back up each other. That is, a TNK3STG board and a TNK2STG board can work in 1+1 hot backup mode. |
