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.

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

OL-15667-03
gsm-abis jitter ms
Sets the number of milliseconds for the jitter. The default value is 4 ms.
Modification
This command was introduced.
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.
