Analog Out-Of-Building Terminals - AT&T 75 Wiring Manual

110-TYPE HARDWARE
Figure 3-100. Connections For Off-Premises Terminals
Installing Out-of-Building Terminal Wiring
Out-of-building terminals are those extensions not physically located in the same building as
the equipment room but are located on the same property.
Analog and digital terminals can be used for out-of-building terminals.

Analog Out-of-Building Terminals

Figure 3-101 shows the connections required for one to eight out-of-building analog voice
terminals. The TN746 Analog Line circuit pack cannot be used for out-of-building terminals.
Carbon block, or equivalent, protection must be provided at both building entrances. The
multi-pair protector units and the out-of-building cabling required must be locally
engineered. Connectorized multi-pair protector units (female 25-pair connector out) are
recommended. The protector units can be ordered from the Premises Distribution Systems
Equipment and Supplies Catalog.
Figures 3-102 shows the connections required for up to 24 out-of-building analog voice
terminals. Concentration of analog line pairs is used at both buildings to minimize the out-
of-building wiring required. The TN746 Analog Line circuit pack cannot be used for out-of
building terminals. In the equipment room, jumpers must be connected between one row in
the green field and up to three rows in the purple field as shown in Figure 3-67. At the out-
of-building terminal location, a WP-90929, List 1 Concentrator Cable is used. There are
eight terminal appearances on each of the three fingers of the concentrator cable.
Carbon block, or equivalent, protection must be provided at both building entrances. The
multi-pair protector units and the out-of-building cabling required must be locally
engineered. Connectorized multi-pair protector units (female 25-pair connector out) are
recommended. The protector units can be ordered from the Premises Distribution Systems
Equipment and Supplies Catalog.
