Z100-Type Hardware; Connector Modules - AT&T 75 Wiring Manual

Z100-TYPE HARDWARE

As shown in Figure 2-1, Z100-type hardware is used for the cross-connect field and for
optional satellite locations. The Z100 hardware consists of the following:

Connector Modules

Connecting Units
Cords (Anti-Snag Modular Plug-Ended Patch Cords and Power Adapter Cords).
Hard-wired (punch-down) connections are not used with the Z100 hardware unless field-
applied 25-pair connectors, modular plugs, or external "junction boxes" (punch-down to 50-
pin miniature ribbon connector) are used (see Figure 2-2).
Connector Modules
Connectorized 25-pair cables terminate on the connector modules. Anti-snag modular plug-
ended patch cords are used to cross-connect the circuits.
The connector modules are preassembled. Each connector module is 5 inches (12.7 cm) wide
and approximately 44 inches (111.8 cm) high. The hardware making up the assembly
consists of one Z9A support, one Z2A jack panel, seven connecting units, seven Z5A
retainers, and one MET/RJ25C connector adapter (test jack).
