3.3.7 Overhead Data Connections – CRS-351 Module to Modems
Your equipment should be connected to the “P1 User Interface” port on the CRS‐351 Overhead
Switch Module. This replaces the direct connection to the Traffic Modem’s “P1 Overhead Data”
port.
Referring to Figure 3‐22:
Connect and secure the CA‐0000006 Control ‘Y’ Cable between the CRS‐351 module and the
SLM‐5650/5650A modems as follows:
• DB‐50F connector labeled “J1 Modem Adapter ‘Y’ Cable” on the CRS‐351 module, and
• DB‐25M “P1 Overhead Data” connectors on the SLM‐5650/5650A Traffic and Redundant
modems.
