Typical Configurations
HotWire Model 7925 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 high speed services across the campus.
Figure 1-1 shows two typical campus applications where remote routers or
multiplexers are interconnected across a campus using two HotWire Model 7925
standalone units. In each pair, one unit is configured as a central site or central
office (CO) and the other is the remote (CP).
Each HotWire Model 7925 standalone unit is configured at the factory to operate
at the CP side of an E1 HDSL connection. However, you can easily reconfigure a
unit for use at the CO end, as would be necessary for the configurations in
Figure 1-1. (Conversely, HotWire Model 7925 nest cards are preconfigured for
CO operation.)
