ISDN Configuration
Router(config)#isdn switch-type primary-qsig
Router(config)#controller t1 0/0
Router(config-controller)#pri-group timeslots 1-24
Router(config-controller)#interface consecutive 0/0:23
Router(config-if)#isdn incoming-voice voice
The afterward accomplish detail the antecedent configuration:
Step 1. Specify the CO about-face blazon on the ISDN interface.
Router(config)#isdn switch-type primary-qsig
You accept a best of configuring the isdn-switch-type command to support
QSIG at either the all-around agreement akin or at the interface configuration
level.
Step 2. Enter ambassador agreement mode.
Router(config)#controller t1 0/0
Step 3. Specify an ISDN PRI group.
Router(config-controller)#pri-group timeslots 1-24
Step 4. Enter articulation anchorage agreement approach for the D channel. Approach 23 is the D
channel because the approach calculation begins at 0. Therefore, Approach 23 is
the 24th channel.
Router(config)#interface consecutive 0/0:23
Step 5. Send admission calls to DSPs.
Router(config-if)#isdn incoming-voice voice
Step 6. Activate the articulation port.
Router(config-if)#no shutdown
