ATM or Frame Relay

Multiprotocol over ATM (RFC 1483) encapsulation or Multiprotocol over
Frame Relay (RFC 1490) encapsulation.
When you select ATM as the datalink protocol, the IAD displays the PVC
and ATM options on the WAN Configuration menu.
When you select Frame Relay, the IAD displays the Frame Relay options on
the WAN Configuration menu

− options 3 and 4 on the menu shown below

(although the example below is the 2208 menu, the 2304 and 2308 Frame
Relay options are also 3 and 4).

TDM Voice (2208s Only)

This option lets you configure, on a per-DS0 basis, voice traffic for the POTS
ports and data traffic for the Ethernet port.

NOTICE:

If no default route is configured on the IAD, the first PPP interface that
completes negotiation will be assigned as the default interface. If
multiple PPP interfaces are configured, this could result in the wrong
interface being assigned as the default. This applies to PPP over
HDLC, PPPoA, PPPoFR, and PPPoE.

Configure

ATM PVCs

You may configure up to eight ATM PVCs on the IAD. Remember always to
reset the IAD to make PVCs active.

Type “3” on the WAN configuration menu (Figure 4.4). The IAD displays

the ATM PVC Configuration menu (Figure 4.23)

NOTICE:

Before you configure PVCs, you must first set the datalink protocol
ATM. If option 3 on the WAN Configuration menu displays Configure
DLCIs instead of Configure PVCs, your datalink protocol is set to
Frame Relay instead of ATM.
