Data Options Available
Every connection includes a minimum of 50 bytes per second in a remote control
channel, for sending ‘session data’ and to provide
T

Tool
Box
capabilities,
and which can be also used to control specific
T
ieline
external devices, i.e.
external relay boxes.
If your codec is captioning-enabled, please see the captioning reference 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.
Please note:
It is possible that when you use
G.722
and
MPEG
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
T
ieline
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].
