Maintenance Manual

Frame errors Frame errors, as A/B where A is the
number of frame errors, and B is the total
number of frames received.
A frame is a unit of audio, the size of which is
dependent on codec.
You should expect to see small values for this
setting. Consistently large numbers typically
imply potential network problems.
Media information If the time stamps or marker bits (or both)
are detected to be unreliable in the
incoming video stream, information will
be displayed here.
This field is not displayed when there is no
problem with the time stamps and marker bits.
Where there is a problem the following text is
displayed: "Media timestamps unreliable",
"Media marker bits unreliable", or both if both
conditions detected.
ClearPath FEC
overhead
The overhead caused by sending FEC
(forward error correction) packets.
ClearPath FEC
recovered
The number of packets recovered by the
MCU through the use of FEC (forward
error correction).
Transmit stream The audio codec being sent from the
MCU to the endpoint, along with the
chosen packet size in milliseconds.
Transmit address The IP address and port to which the
media is being sent.
Encryption Whether or not encryption is being used
on the audio transmit stream by this
endpoint.
This field will only appear if the encryption key
is present on the MCU.
Packets sent A count of the number of packets that
have been sent from the MCU to the
endpoint.
ClearPath FEC
overhead
The overhead caused by sending FEC
(forward error correction) packets.
Video (primary channel and content shown separately)
Receive stream The codec in use and the size of the
picture that the MCU is receiving from
the specific participant. If the picture is
a standard size (for example, CIF, QCIF,
4CIF, SIF) then this name is shown in
parentheses afterwards.
On the MCU 4500 Series, if ClearVision
is enabled on the Settings >
Conferences page, and if it is in use on
this video stream, then the original and
enhanced resolutions are both displayed
here.
Receive address The IP address and port (<IP
address>:<port>) of the device from
which video is being sent
