June 2005 Configuring the RLC
Jitter Buffer target depth
The RLC’s dynamic voice jitter attenuation buffer compensates for the uneven
arrival of voice packets across data networks. This buffer collects packets that
arrive unevenly and relays them evenly.
Select the size of the buffer in the Jitter Buffer drop down box. The valid options
are 30, 60, and 90 milliseconds (ms).
Configure the jitter buffer according to the following guidelines when upgrading
to Remote Gateway 9100 Series product release 1.6:
„
high-speed (>T1 connections) or LANs — leave at the default
„
medium-speed (for example, fractional T1s with speeds of greater than
128K) — set to 60 milliseconds
„
low-speed (64K or ISDN) or high-data environments — configure at 90
milliseconds. This is especially true if using G.711.
