WAN Interface
Introduction The wide area network (WAN) can be divided into X.25 network, frame relay
network, ATM network and ISDN network according to the line type. Accordingly,
the router has synchronous/asynchronous serial interface, ATM interface, ISDN BRI
and CE1/PRI.
Presently, the 3Com Router-supported WAN interfaces include asynchronous serial
interface, AUX interface, synchronous serial interface, ISDN BRI interface CE1/PRI
interfaces, CT3, CT1/PRI interface, E1-F interface, T1-F interface, CE3 interface.
Asynchronous Serial
Interface There are two asynchronous serial interfaces in the 3Com Router. One is Serial,
which sets the synchronous/asynchronous serial interface to work in asynchronous
mode. The other is Async, a special asynchronous serial interface.
You can set asynchronous serial interface to dedicated line mode or dialup mode.
When the asynchronous serial interface is connected with Modem or ISDN
terminal adapter (TA) externally, it can serve as a dialup interface, encapsulating
link layer protocol SLIP or PPP, and supporting IP and IPX.
Configure Asynchronous
Serial Interface Asynchronous serial interface configuration includes:
■Set the synchronous/asynchronous serial interface to work in asynchronous
mode
■Enter the view of specified asynchronous serial interface
