Endpoints and endpoint groups
Table 53: Receive stream statistics (continued)
Field Field description
ClearPath Statistics on the Forward Error Correction used in this stream. The value is Not supported if the
FEC endpoint cannot apply FEC to the stream, or cannot negotiate ActiveControl with the TelePresence
Server.
Otherwise, there are two statistics: the percentage overhead and the number of packets recovered.
The percentage overhead measures how many FEC packets are inserted compared to the original
stream. If the endpoint inserts a copy of every packet in the stream, the overhead is 100%. If the
endpoint inserts a copy of every second packet, the overhead is 50%, and for every fourth packet,
25%. The real statistics will not always perfectly match these levels, owing to the counting interval
and timing of RTCP reports.
The number of packets recovered is a simple count of packets recovered by the TelePresence
Server from the endpoint's FEC packets because the originals were lost.
ClearPath Whether Long Term Reference Frames are used in this stream. The value is Not supported if the
LTRF endpoint cannot send LTRFs, or cannot negotiate ActiveControl with the TelePresence Server.
Otherwise, the value is Enabled, which means that LTRFs are being received by the TelePresence
Server and will be used if necessary.
Table 54: Transmit stream statistics
Field Field description
Transmit The codec used in the transmitted stream. For video and content channels, this also shows the
stream dimensions of the video stream.
Encryption Whether this stream is encrypted.
Channel The negotiated available bandwidth for the Cisco TelePresence Server to send audio/video/content
bit rate to the endpoint.
Transmit This field applies to the video and content transmit streams only and is the bit rate the Cisco
bit rate TelePresence Server is attempting to send at this moment. The actual bit rate, which is simply the
measured rate of video data leaving the Cisco TelePresence Server, displays in parentheses.
Packets The number of audio/video/content packets destined for the endpoint. The second number is the
sent / number of those packets that the endpoint did not receive, as reported by the endpoint.

lost
Frame This field applies to video and content streams. It is the number of frames per second in the
rate transmitted / received streams between the endpoint and the TelePresence Server.
Fast The number of fast update requests (FURs) received by the TelePresence Server on this channel
update from the endpoint.
