Video Format (Rx) The video format received from the far site, such as CIF or
SIF.
Disconnect Reason The description of the Q.850 (ISDN) cause code showing
how the call ended.
Q.850 Cause Code The Q.850 cause code showing how the call ended.
Total H.320 Errors The number of errors during an H.320 call.
Average Percent of
Packet Loss (Tx)
The combined average of the percentage of both audio and
video packets transmitted that were lost during the 5
seconds preceding the moment at which a sample was
taken. This value does not report a cumulative average for
the entire H.323 call. However, it does report an average of
the sampled values.

Average Packets
Lost (Tx)
The number of packets transmitted that were lost during an
H.323 call.
Average Packets
Lost (Rx)
The number of packets from the far site that were lost
during an H.323 call.
Average Latency
(Tx)
The average latency of packets transmitted during an H.323
call based on round-trip delay, calculated from sample tests
done once per minute.
Average Latency
(Rx)
The average latency of packets received during an H.323
call based on round-trip delay, calculated from sample tests
done once per minute.
Maximum Latency
(Tx)
The maximum latency for packets transmitted during an
H.323 call based on round-trip delay, calculated from
sample tests done once per minute.
Maximum Latency
(Rx)
The maximum latency for packets received during an H.323
call based on round-trip delay, calculated from sample tests
done once per minute.
Average Jitter (Tx) The average jitter of packets transmitted during an H.323
call, calculated from sample tests done once per minute.
