Splitter Assembly for STS-1

The CPX offers equipment protection for the STS-1 connection through 1+1 Y-cable redundancy via the STS-1 splitter assembly, Figure 2–15). During switchover, the CPX executes the transition from the active to the protection port so no services are disrupted.

In 1+1 Y-cable protection mode, before switchovers can occur, use JetCraft or JetVision to assign STS-1 ports to a protection group so that the primary and secondary modules can be designated.
