About HotWire Model 7924 Termination Units

Typical Configurations
HotWire Model 7924 standalone units can be used in campus applications where
long loop distances normally require the campus to contract with the local
telephone exchange carrier to deliver private line services across the campus.
Figure 1-1 shows two typical campus applications where remote PBXs or
multiplexers are interconnected across a campus using two HotWire Model 7924
standalone units. In each pair, one unit is configured as a central site or central
office (CO) unit and the other is the remote or customer premises (CP) unit.
The HotWire Model 7924 standalone unit is configured at the factory to operate at
the CP side of a T1 HDSL connection. (Conversely, HotWire Model 7924 nest
cards are configured for CO operation.) The central site unit must be reconfigured
for CO operation in these configurations.
