To Make a New Interconnection

1.At the LIU, locate the cable to be moved and unplug it from the coupling.

2.Carefully unwind the cable from around the retainer rings, remembering the minimum bend radius.

3.If it is necessary to remove the cable from the LIU, carefully guide it through the split rings in the LIU.

4.Locate the appropriate connection on the other side of the interconnect field and carefully route the cable through the split rings of the LIU.

5.Carefully unwind the cable from the retainer rings, remembering the minimum bend radius.

6.Plug the cable into the appropriate connector coupling.

7.Label the cable for the changed circuit.

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

Routing Fiber Optic Cables

Cable Slack Managers or Raised Floors

When using either cable slack managers or raised floors, route the fiber cable to the outside of the carriers behind the rear connector panel and cable troughs. Do not route fiber in the side cable troughs used for the B25A cables. However, since the B25A cables route out of the bottom of the trough, loop slack fiber at the top of the trough.

Protect cables routed between cabinets with a fiber protector cover. When routing fiber to a cabinet that is not adjacent, route the fiber back into and under the top of the intermediate cabinet.

Fiber optic cable requires connection to an LIU or shelf for connection to remote cabinets or for connection to the outside fiber plant. In some systems, it may be necessary to run fiber with the I/O cables such as in the cable slack manager or under a raised floor. In these cases protect the fiber by running it in a dedicated area if possible. In any situation where the fiber optic cable must be run with other cabling, protect it by first running it through flexible conduit.

Overhead Ductwork

With overhead ductwork, route the fiber cable to the outside of the carriers, along the cable troughs, and into the shielded ductwork.

Do not route fiber in the side cable troughs that are used for the B25A cables.

Use the shielded ductwork to manage slack fiber at the top of the cabinet.
