710 CHAPTER 51: CONFIGURING DCC
Configuring the mode of the physical interface
For a synchronous/asynchronous serial interface, configure the physical interface
to operate in asynchronous and dial mode if it is connected to an asynchronous
modem. If the physical interface is connected to a synchronous modem, configure
the physical interface to operate in synchronous and dial mode. For an ISDN BRI or
PRI interface, this step can be ignored.
Perform the following configuration in dial interface (synchronous/asynchronous
serial interface) view.
Table 742 Configure Physical Interface Mode
By default, a synchronous/asynchronous serial interface works in synchronous
mode and an asynchronous serial interface works in dial (modem) mode.
There is no need to configure the physical-mode command for the synchronous
serial interface connected to a synchronous modem. The user only needs to
configure the modem command for an AUX interface.
Configuring link layer and network and routing protocols on the interface
Set the link layer protocol in dial interface (physical or dialer interface) view
through the
link-protocol command, configure an IP or IPX address for the dial
interface through the
ip address or ipx network command, and perform other
configurations in system view.
Table 743 Configure Link Layer and Network and Routing Protocols on the Interface
The linklayer-protocol-type can be SLIP, PPP or Frame Relay. For configuration
details, see the related section in Operation Manual - Link Layer Protocol,
Operation Manual - Network Protocol and Operation Manual - Routing Protocol.
For a dialer interface adopting Resource-Shared DCC to implement Frame Relay
over ISDN, the B channel is encapsulated with PPP originally. Once the B channel is
ready for communication, the protocol encapsulated on the interface dynamically
