Appendix A Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference gsm-abis jitter gsm-abis jitter Sets the amount of transmit jitter delay for the GSM-Abis interface.If the transmit jitter is set to 4 ms, data received on the backhaul with a time equal to 0 milliseconds will be stored in the jitter buffer and transmitted with a time equal to 4 milliseconds. The transmit jitter buffer allows some amount of jitter in the arrival of data on the backhaul to be tolerated without introducing errors into the stream of data. To set the jitter, use the gsm-abis jitter Interface configuration command. gsm-abis jitter ms Syntax Description ms Sets the number of milliseconds for the jitter. The default value is 4 ms. Defaults There are no default settings or behaviors. Command Modes Interface configuration Command History Release 12.4(2)MR Modification This command was introduced. Examples The following example shows how to set the jitter level to 8 ms: Router(config)# interface Serial10/1/0:0 Router(config-if)# no ip address Router(config-if)# encapsulation gsm-abis Router(config-if)# load-interval 30 Router(config-if)# gsm-abis local 10.10.10.2 6661 Router(config-if)# gsm-abis remote 10.10.10.1 5553 Router(config-if)# gsm-abis jitter 8 Router(config-if)# no keepalive Related Commands Command gsm-abis congestion abate gsm-abis congestion critical gsm-abis congestion enable gsm-abis congestion onset Description Sets the congestion abatement detection level at which the remote router will stop suppressing timeslots because congestion has been alleviated. Defines the critical timeslots that are exempt from suppression during congestion onset. Sets the congestion detection algorithm to monitor the transmit jitter buffer and to send congestion indicator signals to the remote when congestion is detected. Sets 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.
