Prerequisites
Procedure steps
NN10600-175 6.1S2
Remove control processor cables for BITS to replace a faulty cable or before
removing the CP-with-BITS from the shelf.
• Removing a BITS cable from the active CP will cause both external
timing sources to be lost, and the provisioned tertiaryReference will
become the active timing reference. Before removing a BITS cable from
an active CP lock the external timing ports. See "Locking external timing
ports" in NN10600-550 Nortel Networks Multiservice Switch
7400/15000/20000 Common Configuration Procedures
• Removing a BITS cable from the inactive CP will have no impact on the
external timing signal being received by the active CP.
1 On the faceplate of the CP, locate the BITS cable to be removed. Refer to
the figure "Control processor with BITS faceplate" (page 331).
2 Disconnect the cable from the CP faceplate and from the BITS
termination panel.
