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.
