FEC Errors (not fixed)
The number of incorrect Forward Error Correction (FEC) video data
values that could not be fixed.
Audio Loopback
Indicates whether the system is in audio loopback (on) or not (off).
The value should be Off.
Video Loopback
Indicates whether the system is in video loopback (on) or not (off).
The value should be Off.
Digital Loopback
Indicates whether the system is in digital loopback mode (on) or not (off).
In this state, any data received by the system is immediately returned to
the transmitting system. The local system still manipulates the data as
though it were a normal connection, but only the data received is looped
back to the transmitter. Data processed for transmission is looped
internally.
TEA Active
Indicates whether the remote system has set its terminal equipment alarm
(TEA). This value is 1 (on) when an internal terminal equipment fault at
the remote site causes the remote site to be unable to receive or to act on
the incoming signal. Normally this value is Off.
Xmit Audio
Indicates whether audio has been enabled for transmitting from the local
end of the connection. Values are G.711 Alaw, G.711 µlaw, G.722, G728,
or Off.
