The following table describes the current network channel statistics
for SG3 communications.
Description
The sum of video errors
that were not caused by an
error in the channels
The number of packets
with errors that were
discarded because they
included an uncorrectable
error or could not be
decoded
The sum of the
uncorrected packets for all
active channels
The number of packets
received from the far end
by each channel without
error
The number of packets
with errors that were
received from the far end
by each channel and were
corrected by the error-
correction software
Using the Diagnostics Menus
Interpretation
A large number of errors indicates a faulty
transmitting AP board at the far-end site
or a faulty receiving AP board at the near-
end site.
After the call, place the systems at each
site in local channel loopback mode. The
system with the checksum errors has the
faulty board.
High numbers indicate a transmission line
problem or, less frequently, a CSU
problem. If your system uses an external
CSU, the cabling to the CSU may be faulty.
Verify the numbers by running a near-end
local channel loopback test.

Packets
This indicates that the transmission line
and the CSUs are valid.
Small numbers for this statistic are
expected during normal operation.
High numbers indicate a transmission line
problem or, less frequently, a CSU
problem. If your system uses an external
CSU, the cabling to the CSU may be faulty.
Verify the numbers by running a near-end
local channel loopback test.
