Simple Remote Bridging
The OfficeConnect Remote uses FastConnect, its own
protocol, to ensure the most efficient connection
with other OfficeConnect Remote units. However, if
you are connecting to a different type of
bridge/router the standard PPP communications
protocol is required to establish the link. You can
configure outgoing calls to use either FastConnect
or PPP as required. The ISDN port on the
OfficeConnect Remote autosenses the protocol
being used on incoming calls and switches to the
protocol necessary for that connection.
If you are using ISDN to connect to different networks,
the two B channels can be used independently to
connect to different networks at the same time.
Building a Larger Network
Large networks of interconnected LANs can be
established by using multiple bridges as illustrated
in
.
The bridges build up their address tables. If the
destination unit is not registered as being accessed
via the bridge’s LAN interface, the frame will not be
placed on LAN A. Therefore, frames passing between
LAN B and LANs C or D will not impact the overall
performance of the LAN.
