Local Channel Loopback
The local channel loopback is performed within the channel user interface, by
returning the transmit signal arriving from the user on the receive path. At the
same time, the transmit channel signal is connected to the input of the transmit
path and is sent to the remote user. When everything works O.K., the local user
should receive its own transmission.
The loopback signal path is shown in figure 3-2.

Remote Channel Loopback
The remote channel loopback is performed within the local channel user
interface, by returning the signal received from the remote user on the transmit
path. The signal arriving from the remote user is also available to the local user.
When everything is working O.K., the remote user should receive its own
transmission.
The loopback signal path is shown in figure 3-3.
