Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Configuration Sequence
For example, the following command configures the gsm-abis congestion abate detection level to a
value 250 ms:
Router(config-if)# gsm-abis congestion abate 250
Note The abate detection level is defined as x milliseconds of continuous congestion abatement (that is, no
congestion indications).
Step 4 To set the congestion onset detection level at which the remote router will start suppressing all timeslots
that are not defined as critical in an effort to alleviate the congestion, enter the following command.
Router(config-if)# gsm-abis congestion onset ms
Where ms is the value of the congestion onset in milliseconds.
For example, the following command configures the gsm-abis congestion onset detection level to a
value 100 ms:
Router(config-if)# gsm-abis congestion onset 100
Note The onset detection level is defined as x milliseconds of continuous congestion detected.
Step 5 To define the critical timeslots that are exempt from suppression during congestion onset, enter the
following command.
Router(config-if)# gsm-abis congestion critical timeslot-range
Where timeslot-range specifies a value or range of values for time slots that are exempt from suppression
during congestion onset. Use a hyphen to indicate a range.
For example, the following command configures the gsm-abis congestion critical timeslot range as
1-10:
Router(config-if)# gsm-abis congestion critical 1-10
Note These are the timeslots that contain signalling and control information exchanged between the BSC and
BTS.
