Installing the Stratum 3 Clock
Install the Stratum 3 Clock Wiring
- Connect the B25A cables from the TN780 connector panel slot on the system cabinet and the Stratum 3 Clock to the cross-connect module in the yellow field.
- Connect the CSU plug end of the H-600-274 (Y) cable to the primary CSU. Route an H600-307 cable from the DS1 connector panel slot on the system cabinet to the connector on the "SYSTEM" end of the "Y" cable.
- Route a B25A cable from the "CLOCK" end of the "Y" cable to the cross-connect module in the yellow field.
- Repeat steps 2 and 3 for the secondary CSU. The maximum allowable cabling distance between the Stratum 3 clock and the CSU is shown in Maximum Cabling Distance.
- For standard reliability systems, refer to Cross-Connects for Standard Reliability to cross-connect the TN780 and "CLOCK" end connections to the Stratum 3 Clock connections on the cross-connect module.
- For high or critical reliability systems, refer to Cross-Connects for High or Critical Reliability to cross-connect the TN780 and "CLOCK" end connections to the Stratum 3 Clock connections on the cross-connect module.
- The common cross-connection from the TN780 in A and B carriers to the Stratum 3 Clock should be done by bridging the jumper wires.
- Dress the cables down sides of the cabinet and run through the Cable Slack Manager, if provided.
- Administer per the DEFINITY Enterprise Communications Server Administrator's Guide.
