Data Description
Total H.320 Errors The number of H.320 errors experienced during the
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
five seconds preceding the moment at which a sample
was taken. This value does not report a cumulative
average for the entire 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
five seconds preceding the moment at which a sample
was taken. This value does not report a cumulative
average for the entire call. However, it does report an
average of the sampled values.
Average Packets Lost (Tx) The number of packets transmitted that were lost
during a call.
Average Packets Lost (Rx) The number of packets from the far site that were lost
during a call.
Average Latency (Tx) The average latency of packets transmitted during a
call based on round-trip delay, calculated from sample
tests done once per minute.
Average Latency (Rx) The average latency of packets received during a call
based on round-trip delay, calculated from sample tests
done once per minute.
Maximum Latency (Tx) The maximum latency for packets transmitted during a
call based on round-trip delay, calculated from sample
tests done once per minute.
Maximum Latency (Rx) The maximum latency for packets received during a
call based on round-trip delay, calculated from sample
tests done once per minute.
Average Jitter (Tx) The average jitter of packets transmitted during a call,
calculated from sample tests done once per minute.
Average Jitter (Rx) The average jitter of packets received during a call,
calculated from sample tests done once per minute.
Maximum Jitter (Tx) The maximum jitter of packets transmitted during a call,
calculated from sample tests done once per minute.
Maximum Jitter (Rx) The maximum jitter of packets received during a call,
calculated from sample tests done once per minute.
