Data Description
Video Protocol (Tx) The video protocol transmitted to the far site, such as H.263
or H.264.
Video Protocol (Rx) The video protocol received from the far site, such as H.261
or 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 Reason Reason for the call to disconnect
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 Percent of
Packet Loss (Rx)
The combined average of the percentage of both audio and
video 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
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.
Average Jitter (Rx) The average jitter of packets received during an H.323 call,
calculated from sample tests done once per minute.
Maximum Jitter (Tx) The maximum jitter of packets transmitted during an H.323
call, calculated from sample tests done once per minute.
Maximum Jitter
(Rx)
The maximum jitter of packets received during an H.323 call,
calculated from sample tests done once per minute.
