Figure 1-1 Typical Low-Speed Transmission Application
Figure 1-2 shows a typical application for an HS-R module used in conjunction
with ASMi-31 modems.
In this application, the HS-R module is used to connect remote terminals, via a
Megaplex link:
• At the local end, the terminals are directly connected to HS-R channels.
• At the remote location, the channels of the HS-R module are routed to an
HS-U/1 module. The “U” interfaces of the HS-U/1 module, which is
configured for operation in the LT (line termination) mode, are connected to
separate ASMi-31 short-range modems, offered by RAD, using standard
telephone (twisted pair) loops. The remote terminals are connected to the
ASMi-31 units with V.110 support.
The maximum range between the HS-U/1 module located at the remote location
and the ASMi-31 units, can be up to 5.5 km, thus providing additional flexibility in
system configuration.
