When data is sent in transparent mode you require sustained data flow to transfer
data reliably. This is network dependent and if the network is unreliable there
may be some loss of data packets, more bit errors (1/1000) and therefore
dropouts in audio.
In non-transparent data mode, Radio Link Protocol (RTP) is used, providing
better error correction and less bit errors (1/100,000,000). Data is buffered when
it is being sent and received from a GSM module or cell-phone in this mode. This
mode is more reliable for a data call and

GSM modules only support the
sending of non-transparent data. We also recommend that you use non-
transparent data mode when you use a
Nokia
®
6310i cell-phone.
If your SIM card is set to transparent mode you will be unable to receive any calls
to your cell-phone or GSM module. Contact your telco to check if your SIM card
has been set to non-transparent data mode and get them to switch it if it hasn’t.

DTMF Control of 3
rd
Party Devices
It is possible to control 3
rd
party devices using the DTMF control menu on your
codec. To access this menu select [Menu] > [DTMF Control].
To utilize DTMF control from a codec you require a POTS module connected to
a POTS line. The POTS module needs to be in voice mode. To program this
select the POTS connection that you wish to use for DTMF with the
MENU
SELECTOR
. Next, select
SOFTKEY 3 Wiz
then press
OK
and scroll to and
select
Setup Voice Analog
. Press
OK
to complete the configuration.
Please note:
The other way to configure a plug-in module for voice mode is to
select [Menu] > [Configuration] > [POTS Left/Right Setup] > [Operating Mode] >
[Voice Analog].
Plug the other end of the POTS connection into the device you wish to control.

DTMF Control via ISDN
An ISDN module can be used for DTMF control of a device if the module is
used in ISDN voice call mode. To program an ISDN module for voice mode
simply select the G.711 algorithm and the codec will make an outgoing
analog call. This is automatically selected if an analog call is received by the
codec.
