Chapter 5 Configuring the Voice Interfaces
T1/E1 Configuration (H.323)
Step 2 Configure parameters for the voice interface.
a. Specify the PRI group and time slots to be mapped.
gateway(config-controller)# pri-group timeslots 1-31
b. Configure each channel group as a virtual serial interface.
gateway(config-controller)# interface serial 1/0:31
c. Specify the E1 interface, unit number, and channel group to modify, as in the following example:
interface Serial1/0:23
no ip address
no logging event link-status
isdn switch-type primary-5ess
isdn incoming-voice voice
no cdp enable
Note After completing these steps, configure the route pattern and dial plan and save your
configuration, as described in “H.323 Gateway Configuration” section on page 5-12.
