channel, for sending ‘session data’ and to provide

and which can be also used to control specific

external devices, i.e.
external relay boxes.
If your codec is captioning-enabled, please see the captioning user manual for
more information on data transfer and setting your codec up.
For specific GSM data information, please see the section in this reference
manual titled GSM Transparent and Non-transparent Data Modes. For all other
data information, please see the section of this reference manual titled Data

Please note:
It is possible that when you use
G.722
and
MP2
algorithms to connect to a non-
T
ieline
codec, the ’framing’ process (where incoming bit streams are identified
and distinguished for individual decoding) can be unsuccessful when a call is
initiated. This can be solved by turning off the ‘session data’ stream sent by the
Tieline codec. To do this select [Menu] > [Configuration] > [System Settings] >
[Session Data] > [Disable]. Please note that this is a global setting and will also
affect all POTS, and IP connections on the codec.
If you try to connect to a
T
ieline
codec with session data disabled, you will have to
ensure that the connection settings on both codecs are identical because dialing
codec session data normally provides this information to the remote codec. To
avoid this problem, simple re-enable session data [Menu] > [Configuration] >
[System Settings] > [Session Data] > [Enable].
