Configuring DCC 727

Table 763 Implement ISDN Caller Identification Callback (Client Configuration) in Resource-Shared DCC

Operation	Command
Configure the dial number for calling a	dialer number [ dial-number]
remote end

To configure the ISDN caller identification callback server in the resource-shared DCC implementation, perform the following configuration in dialer interface view.

Table 764 Implement ISDN Caller Identification Callback (Server Configuration) in Resource-Shared DCC

Operation	Command
Configure the local end to implement	dialer call-in remote-number[
ISDN callback according to the ISDN caller	callback ]
identification
Disable the local end to implement ISDN	undo dialer call-in remote-number[
callback according to the ISDN caller	callback ]
identification
Configure the dialer number for calling a	dialer number [ dial-number]
remote end

By default, callback according to ISDN caller identification is not configured.

A dialer number should be configured on the dialer interface at server end through the dialer number command, but it is not required to be exactly the same as the dial-in dialer number.

Configuring ISDN leased line

This function can only be used with circular DCC and must be implemented after circular DCC has been configured. ISDN leased line application is fulfilled through establishing semipermanent ISDN MP connections. Such application requires that a leased line has been established on the PBX of the telecommunication service provider and has been connected to the remote device.

Perform the following configuration in dial interface (ISDN BRI or PRI interface) view.

Table 765 Configure ISDN leased line for Circular DCC

Operation	Command
Configure a B channel for ISDN leased line	dialer isdn-leased channel-number
connection
Delete the B channel for ISDN leased line	undo dialer isdn-leased
connection	channel-number

By default, no B channel is configured for ISDN leased line connection.

Configuring auto-dial

This function can only be used with circular DCC. With a circular DCC, after the router is started, the DCC will automatically attempt to dial the remote end of the connection without requiring a triggering packet. If a normal connection cannot be established with the remote end, DCC will automatically retry at a certain interval. Compared with the auto-dial DCC triggered by packets, such connections
