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 1-1shows 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.
