1000-A2-GN22-00 3. Installing the CPX-1000
Step 1 Connect two pairs of STS-1 transmit and receive cables to the STS-1
primary and corresponding standby transition modules in the
back of the CPX shelf.

primary and standby transition modules to the corresponding Tx1,
Rx1, Tx2 and Rx2 connectors on the back of the Splitter Assembly.
Step 3 Connect a pair of STS-1 transmit and receive cables to the TO NET
and FROM NET connectors of the STS-1 Splitter Assembly.
Step 4 Connect the transmit and receive cables to the corresponding
connectors on the Class 5 switch.
Step 5 Dress the STS-1 and power cables from the rear of the shelf, so the
