Chapter 4 Configuring the Data Interfaces
Task
Step 8
Specify the channel group and time slots to be mapped.
When configuring a E1 data line, channel-group numbers
can be values from 0 to 30.
Time slots are assigned to channels. One or more time
slots or ranges of time slots belong to the channel group.
The first time slot is numbered 1. For an E1 controller,
the time slot range is from 1 to 31. For E1 PRI scenarios,
all 31 T1 time slots are assigned as ISDNPRI channels.
The default line speed when configuring an E1 controller
is 64 kbps.
In this example, channel-group 0 consists of five time
slots and runs at a speed of 64 kbps per time slot.
Step 9
Configure each channel group as a virtual serial
interface. Specify the E1 interface, unit number, and
channel group to modify and enter the interface
configuration mode.
You know you have entered interface configuration mode
when the prompt changes to
Step 10
Assign an IP address and subnet mask to the interface.
Step 11
Exit back to global configuration mode.
If your Catalyst 4224 has more than one CE1/PRI
interface that you need to configure, return to Step 4.
Step 12 When you finish configuring interfaces, return to enable
mode.
