Installing The Cable Slack Managers; Labeling The Cross-Connect Field - AT&T 75 Wiring Manual

66-TYPE HARDWARE

Installing the Cable Slack Managers

To install the cable slack managers, proceed as follows:
1 .
Position the Z113A cable slack manager against the wall under the cross-connect
field, aligning the side of the manager with the first connecting block column of
the Trunk/Auxiliary Field.
2 .
Position the next cable slack manager under the cross-connect field and alongside
the previously installed cable slack manager, insuring that tabs and interlocks
align and snap together.
3 . Repeat step 2 until all cable slack managers are installed.
Note: Nine 1/4-inch (6.4-mm) diameter holes are provided in the cable slack manager
bases for earthquake mounting if required. Also, if the cable slack managers are
mounted on an uneven floor, shims may be required to keep the cable slack managers
level and insure proper fit of the covers. Holes are also provided in the sides of the
base for bolting the cable slack managers together. Bolts and shims must be locally
provided.

Labeling the Cross-Connect Field

The cross-connect field is color-coded to identify system wiring as follows:
Green—Leads to central office
Purple—Leads to switch ports
Yellow—Leads to auxiliary equipment and miscellaneous switch leads
Blue—Leads to information outlets
White—Leads from the cross-connect field to the satellite locations (3-pair).
A permanent felt-tipped pen can be used to write the lead designations on the 66-type
connecting blocks (Figure 4-19). Table 4-G shows the lead designations for the switch port
appearances at the cross-connect field, and Table 4-H shows the auxiliary lead designations
for the auxiliary circuits. Any time these leads are cross-connected to another connecting
block they should be labeled at that block also.
