Configuring the PA-2CE1 Interfaces
Step 13
Write the new configuration to memory as follows:
Router# copy running-config startup-config
[OK]
Router#
The system displays an OK message when the configuration is stored.
Exit the privileged level and return to the user level by entering disable at the prompt as follows:
Step 14
Router# disable
Router>
This completes the procedure for creating a basic channelized E1 configuration. Proceed to the
"Checking the Configuration" section on page 4-12 to check the interface configuration using show
commands. For additional information about configuring channelized E1 interfaces, refer to the
publications Wide-Area Networking Configuration Guide and Wide-Area Networking Command
Reference.
Configuring Channelized E1 ISDN Interfaces
The PRI group must be mapped before the 2CE1 controller can be configured (there is only one PRI
group for each controller). The following are controller commands used to map the PRI group:
•
•
•
•
•
•
•
If you do not specify the timeslots, the controller is configured for 30 B channels
Note
(timeslots 1 to 15 and 17 to 31) and one D channel (timeslot 16).
Note
Cisco 7000 series and Cisco 7500 series routers identify the PRI group as a serial interface
by chassis slot number, port adapter slot (0 or 1), interface port number (0 or 1), and
timeslot 16. For example, the address of the 2CE1 installed in chassis slot 3, port adapter
slot 1, interface port 1, and timeslot 16 would be recognized by the system as serial
3/1/1:15.

pri-group [timeslots list]
pri-group timeslots is a number between 1 to 31. (Timeslots 1 to 15 and 17 to 31 represent the
B channels, and timeslot 16 represents the D channel. While the numbering scheme for entering
timeslots is 1 to 31, the system recognizes the numbering of timeslots as 0 to 30. The PRI group is
configured by using timeslot 16 [the D channel], which is recognized by the system as timeslot 15.)
You can enter timeslots individually and separate them by commas or enter them as a range
separated by a hyphen (for example, 1-3, 8, 9-18). The default DS0 speed of the PRI group is 64
kbps.
