Routing Cable Guidelines - AT&T 75 Wiring Manual

Figure 4-21 shows the proper label installation on a 25-pair cable connector (see Note).
Note: The label should be installed near the rear of the connectors shown so that it
will not be obscured by any of the switch cabinet connector retainers. It can also be
installed on the skin of the cable near the connector.
Figure 4-21. Self-Stick Label Installation on 25-Pair Cable Connector
If cable labels are not used with 66-type hardware, the proper labeling information can be
written on both the cable connector and the velcro cable retainer at the 157B connecting
block using a permanent felt-tipped pen.

Routing Cable Guidelines

The following guidelines should be followed when installing the equipment room cabling.
Following these guidelines will make optimum use of the cable slack managers and make
future cabling additions and changes easier.
General
Figure 4-22 shows cable routing through the cable slack manager for a 1-cabinet installation
using cable routing from the bottom. Figure 4-23 shows cable routing through the cable
slack manager using cable routing from the top. Cables route through the cable slack
manager in either the cabinet or wall troughs or when needed through the two center
troughs.
Port cables should use the cabinet trough for the parallel runs. The station cables should
use the wall trough. The center troughs are used after the cabinet and wall troughs are
filled.
Figure 4-24 shows typical cable routing from the switch cabinet to the cross-connect field
using cable routing from the bottom. Figure 4-25 shows cable routing from the switch
cabinet to the cross-connect field using cable routing from the top.
