Paradyne CPX-1000 manual STS-1 Splitter Connections, To Net, From Net

1000-A2-GN22-00 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):
