2. CPX-1000 Voice Services Platform Description
This architecture enables two types of STS-1 module switchovers:
Automatic/forced switchover
—the system detects a
problem such as loss of signal and performs a forced
switchover to the standby STS-1 module in the protection
group. When receive paths on an STS-1 module fails,
processing switches over to the standby STS-1 module.
Administrative switchover
—the network administrator
initiates the switchover to the standby STS-1 module.
Each pair of redundant STS-1 cards has the following connections
at the STS-1 splitter assembly (
Table 2–9
):
