Typical Configuration Example

Interconnect Routers for Data Transmission via ISDN PRI Line

I. Networking Requirement

Router A is connected with router B via WAN, as shown in the following diagram.

III. Configuration Procedure

1Configure Router A:

a Create an ISDN PRI interface.

[Router]controller e1 0

[Router-E1-0]pri-set

[Router-E1-0]quit

bConfigure the ISDN PRI interface.

[Router]interface serial 0:15 [Router-Serial0:15]ip address 202.38.154.1 255.255.0.0

[Router-Serial0:15]dialer route-info ip 202.38.154.2 8810154

[Router-Serial0:15]dialer-group 1

[Router-Serial0:15]quit[Router]dialer-rule 1 ip permit

2Configure Router B:

The parameter configuration on Router B is almost the same as Router A, so it will not be mentioned here.

Typical ISDN DoV	I. Networking Requirements
Configuration Example	RouterA and Router are connected over an ISDN and RouterA will initiate a call to
	RouterB. The call is handled in the way of processing a voice call, and RouterA and
	RouterB transmit data after the call is set up.
