Data Description
Video Protocol The video protocol transmitted to the far site, such as H.263 or
(Tx) H.264.
Video Protocol The video protocol received from the far site, such as H.261 or
(Rx) H.263.
Video Format (Tx) The video format transmitted to the far site, such as CIF or SIF.
Video Format (Rx) The video format received from the far site, such as CIF or SIF.
Disconnect The description of the Q.850 (ISDN) cause code showing how the
Reason call ended.
Q.850 Cause The Q.850 cause code showing how the call ended.
Code
Total H.320 Errors The number of errors during an H.320 call.
Average Percent of The combined average of the percentage of both audio and video
Packet Loss (Tx) 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 Percent of The combined average of the percentage of both audio and video
Packet Loss (Rx) packets received 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 The number of packets transmitted that were lost during an H.323
Lost (Tx) call.
Average Packets The number of packets from the far site that were lost during an
Lost (Rx) H.323 call.
Average Latency The average latency of packets transmitted during an H.323 call
(Tx) based on round-trip delay, calculated from sample tests done once
per minute.
Average Latency The average latency of packets received during an H.323 call
(Rx) based on round-trip delay, calculated from sample tests done once
per minute.
Maximum Latency The maximum latency for packets transmitted during an H.323 call
(Tx) based on round-trip delay, calculated from sample tests done once
per minute.
Maximum Latency The maximum latency for packets received during an H.323 call
(Rx) 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.
Average Jitter (Rx) The average jitter of packets received during an H.323 call,
calculated from sample tests done once per minute.
