status station
Page 4 of this command generates a snapshot jitter buffer size (ms) and packet
loss report for a particular station. This command is available to all login
permissions.
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 a status station command 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 the Administration for
Network Connectivity for Avaya MultiVantage Software.
