Configuration and dialling memories
To ease the operation, it is possible to store configuration memories, called "profiles". These belong to
three categories:
"Call profiles", including the parameters for calling a given destination: dial numbers, coding
algorithm, etc. A profile is similar to a phone directory item, but in addition it can also hold
coding parameters. Recalling such profile directly configures the codec and/or triggers an
outgoing call with the parameters that have been previously stored by the user into this profile.
"Presets" which memorise the network access characteristics. Recalling a preset is a quick way
to recover the configuration needed for connecting on a given line/network.
"Snapshots" which memorise all the settings for the audio interfaces.
These various profiles can be used locally and also through the web pages, and they can be
imported/exported from/to a computer.

Test functions
For maintenance purposes, some test loops can be activated. The following drawing schematically
shows these test loops:
Figure 5 – Test loops
"Audio loop": uncompressed audio data are looped from the input of the encoder to the input
of the output conversion functional block. This loop redirects the audio input to the audio
outputs;
"Loop 3", or "Codec" loop: compressed audio data are looped just before the network
interface;
Note: this test loop is not available for every network interface.
"Loop 2", or "Network" loop: this loop sends the received data back to the network; for the
remote codec, the effect is the same as a loop 3 when the transmission works correctly;
Note: this test loop is not available for every network interface.
"Audio feedback" loop (audio output to audio input); this allows the codec to send back to the
remote codec the signal it receives, after decoding and re-encoding.
Note: due to the location of the audio test points, the level indicators are not influenced by the test
loops.
