Chapter 3 Basic Configuration Using the Command-Line Interface
Configuring ISDN PRI
Note Your Cisco AS5350 or Cisco AS5400 supports a total of 248 ISDN channels per ingress trunk card. If
you are configuring individual T1 channels of your CT3 for backup links or serial backhaul connections,
the CT1s must be configured into channel-groups—each channel-group using 24 timeslots or channels.
For example, to configure 6 CT1s (6x24), 144 ISDN channels are in use leaving a remainder of 104
(248–144) channels for ISDN use. See the “Configuring ISDN PRI” section on page 3-13.
In the following show running-config example, six CT1s are configured into channel-groups:
