The following parameters are displayed:
Participant Properties - Channel Status Parameters
Field Description
Channels Used When checked, indicates the channel type used by the participant to connect to the
conference: Incoming channels are endpoint to MCU, Outgoing channels are from
MCU to endpoint.
Channels:
H.225/Signaling - The call-signaling channel.
H.245/SDP - The Control channel.
Audio in - Incoming audio channel
Audio out - Outgoing audio channel
Video in - Incoming video channel
Video out - Outgoing video channel
Content in - H.239/People+Content conferences
Content out - H.239/People+Content conferences
FECC in - The incoming FECC channel is open.
FECC out - The outgoing FECC channel is open.
Columns:
•Faulty – A red exclamation point indicates a faulty channel condition. This is a
real-time indication; when resolved the indication disappears. An exclamation
point indicates that further investigation may be required using additional
parameters displayed in the Advanced Channel Status tab.
•Bit Rate – The actual transfer rate for the channel. When channel is inactive, bit
rate value is 0. For example, if the participant is connected without video, the bit
rate for the video channel is 0.
Note: The CTS Audio Auxiliary channel is used only for Content. In all other
cases, the bit rate shown in this column for this channel is 0.
Packet Loss – The accumulated count of all packets that are missing according
to the RTCP report since the channel was opened. This field is relevant only
during the connection stage and does not display faulty indications.
Fraction Loss (Peak) – The ratio between the number of lost packets and the
total number of transmitted packets since the last RTCP report. Peak (in
parentheses) indicates the highest ratio recorded since the channel was opened.
Number of Packets – The number of received or transmitted packets since the
channel has opened. This field does not cause the display of the faulty indicator.
Jitter (Peak) – Displays the network jitter (the deviation in time between the
packets) as reported in the last RTCP report (in milliseconds). Peak (in
parentheses) reflects the maximum network jitter since the channel was opened.
Latency – Indicates the time it takes a packet to travel from one end to another
in milliseconds (derived from the RTCP report).
High latency value may indicate that there is a problem in the network, or that
the endpoint is sending an incorrect RTCP values.
