	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

Configure 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.

Asynchronous serial interface configuration includes:

■Set the synchronous/asynchronous serial interface to work in asynchronous mode

■Enter the view of specified asynchronous serial interface
