Making Changes at an LIU or Shelf

Circuit changes are made by moving the fiber optic patch cords to other couplings.

To Remove a Fiber Optic Patch Cord

1.At the LIU or shelf, locate the correct patch cord and unplug it from the coupling.

2.Carefully remove the cable from the LIU and from the trough.

NOTE:

Take care to ensure the patch cord is not bent beyond the minimum bend radius of 1.5 inches (3.8 cm).

3.Trace the other end of the patch cord to its termination point and unplug it.

4.Remove the label associated with the removed patch cord.

5.Place plastic covers over the connectors to prevent dust or damage.

To Make a New Cross-Connection

1.At the LIU or shelf, locate the connector couplings associated with the circuit to be added.

2.Select a patch cord of the appropriate length for the cross-connection to be made. Excess cord length causes congestion in the trough and may cause the cable to be damaged.

3.Plug 1 end of the cord into the appropriate connector coupling.

4.Route the patch cord through the LIU or shelf and into the vertical and horizontal troughs.

5.Plug the other end of the patch cord into the appropriate connector coupling on the fiber optic transceiver on the DEFINITY System.

6.Label the cable for the circuit added.

7.Test the circuit using the test fiber link commands in DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r.
