About HotWire Model 7915 Standalone Termination Units
Typical Configurations
HotWire Model 7915 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 a typical campus application where remote multiplexers or
routers are interconnected across a campus using two HotWire Model 7915
standalone units. One unit is configured as a central site or central office unit
(CO) and the other is the customer premises (remote) unit (CP).
Each HotWire Model 7915 standalone unit is configured at the factory to operate
at the CP side of an E1 SDSL connection. However, you can easily reconfigure a
unit for use at the CO end, as would be necessary for the configuration in
Figure
1-1. (Conversely, HotWire Model 7915 nest cards are preconfigured for
CO operation.)
A V.35-compatible unit on the CO side may be set for internal or external timing.
A V.35-compatible unit on the CP side uses the SDSL local loop for a timing
source.
