Selecting GSM Voice Mode
Programming GSM voice mode can be done in one of two ways – either using
the codec menus or using

use the GSM wizard. Select the GSM connection that you wish to connect with
using the
MENU SELECTOR
. Next, select
SOFTKEY 3 Wiz

field unit codec (before
PPM metering is displayed).
You can now connect your GSM voice enabled codec from the field to the studio.
If you choose to dial another
T
ieline
codec in the studio it must be set to POTS
Voice mode.
It is also possible to program
GSM voice mode using the
GSM LL/GSM/USB-3G
menu in
Tool
Box
software.
To do this use the
GSM
Wireless Network Type
drop-
down menu and select
GSM
