Definition
In this instance, jitter is the variability in the amount of time (in milliseconds) that
packets are received over the network. When jitter increases, the user
experiences a noisy connection, delays, and a general loss of quality, making
speech unintelligible.
NOTE:
If you issue status station for a non-IP station or the connection is
hairpinned or shuffled, then the packet loss and jitter size information (page
4) does not appear. See also “Shuffling, Hairpinning, Codec and
Inter-Network Management Features” in Avaya MultiVantage Administration
for Network Connectivity.
