1.5 Transmission Protocols
1.5.1 Frame Relay
The WIMAN system supports the Frame Relay protocol widely
used at many Telephony companies.
It operates smoothly in Frame Relay networks and enables the
application of commercial Frame Relay compatible Router as
switches on the STAR- and the ACCESS side.
Except for the supply of an Internet access, it is additionally
possible to use the WIMAN Frame Relay system for telephony
uses. Therefore, commercial Frame Relay multiplexers from
companies such as RAD, NUERA, CISCO, etc. can be used.
The Frame Relay support is a software-configurable feature and
is starting from the software-Version T.05. This software ver-
sion does also support leased line functionality.
