OVERVIEW
to hook up a set of V.35 async equipment to one, two, or
three synchronous Frame Relay/X.25 wide-area links and
switch between them all?
(Fradswitch A) is designed to do. It’s a high-performance
switch that you can use for routing between async devices
and X.25 or Frame Relay connections.

pinned out on RJ-45 connectors.
protocols: Besides the standard ones for X.25 and Frame Relay,
the Fradswitch also supports HDLC and SDLC, the proprietary
stat-mux protocol STM (for use with our Stat-8 mux), plain
async, and SLIP/encapsulated IP.
their maximum data rate is 115.2 kbps for each port. (This is
also the top rate for each async channel.) If you configure the
main-link ports to use a sync protocol, they have an aggregate
