Near End Loop
The Near End Loop screen allows you to test the encoder/decoder
on the ViewStation. This can help you diagnose a problem with a
video call. Press any button on the remote control to stop the loop.
Far End Loop
The Far End Loop screen only appears during an H.320 or V.35 call
and allows you to test the encoder/decoder on the ViewStation. This
can help you diagnose a problem with an H.320 or a V.35 video call.
If you perform a far-end loop test during a call, the far site sees its
own loop. Press any button on the remote control to stop the loop.
