Configuration Sequence
With a Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router slot 0 (physical slot
HWIC0), for example, the following command specifies the E1 controller as the first port of the
Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router slot 0 (physical slot HWIC0):
Router(config)# controller e1 0/1/0
Router(config-controller)#
Enter the clocking source (see
Step 3
information).
Router(config-controller)# clock source {line [primary] | internal}
Where:
line—Specifies the E1 line from which the clocking is taken.
•
internal—Specifies internal clocking.
•
primary—Primary clock source.
•
For example, the following command configures the clock source for the E1 controller:
Router(config-controller)# clock source internal
When you are using the clock source {line [primary] | internal} command to change the configuration
Note
of an installed card, you must enter the no clock source {line [primary] |internal} command first. Then
enter the clock source {line {primary] | internal} command for the new configuration information.
Step 4
Specify the channel-group and time slots to be mapped. Once you configure a channel-group, the serial
interface is automatically created.
Router(config-controller)# channel-group channel-no timeslots timeslot-list speed {64}
Where:
•
channel-no—ID number to identify the channel group. The valid range is 0 to 30.
•
timeslot-list—Timeslots (DS0s) to include in this channel group. The valid timeslots are 1 to 31.
•
speed {64}—The speed of the DS0: 64 kbps.
For example, the following command configures the channel-group and time slots for the E1 controller:
Router(config-controller)# channel-group 0 timeslots 1-31 speed 64
Note
When you are using the channel-group channel-no timeslots timeslot-list {64} command to change the
configuration of an installed card, you must enter the no channel-group channel-no timeslots
timeslot-list speed {64} command first. Then enter the channel-group channel-no timeslots timeslot-list
{64} command for the new configuration information.
Exit back to global configuration mode.
Step 5
Router(config-controller)# exit
To Configure the GSM-Abis interface, first specify the serial interface that you want to configure by
Step 6
entering the interface configuration mode.
Router(config)# interface serial slot /subslot/ port:channel-group
Where:
slot—Number of the slot being configured.
•
subslot—Number of the subslot being configured.
