Codec Module Options
This section of the reference manual will describe the module alternatives
available for use in the
COMMANDER
G
3
codec. Hyperlinks to other sections of
the manual will assist you to set up the various functions.
Both the
COMMANDER
G
3
field and rack units enable operators to literally build
their own codec to suit the conditions of each broadcast. Each codec features two
expansion slots, which accept your choice of POTS, ISDN, GSM, 3G (USB) or
X.21 modules. This enables operators to simply select and plug in the desired
telecommunications medium that is optimally suited to the broadcast location.
The
COMMANDER
G
3
can accept single or multiple module combinations such
as:
The on-board POTS modem used with one analog telephone line.
The on-board POTS modem and one POTS module, each requiring
one analog telephone line at the remote site.
One ISDN module which requires one ISDN line with up to two B
channels
One ISDN line and one POTS module. ISDN can be used as the
primary link and the POTS line can be used as a backup program
feed.
A GSM module can be used independently or in combination with an
ISDN, POTS or other modules. GSM does not require any wiring as it
uses a GSM cell-phone connection.
Two GSM connections can be used, using one GSM module and a
GSM cell-phone connected to the
RS 232
port on the codec.
Two IP/Internet connections using either the UDP or TCP protocols,
via the Ethernet LAN connection port on
T
ieline
codecs.
A 3G/IP connection via a USB module connected to a 3G cell-phone
or USB modem.
A 3G connection via an HSDPA or EV-DO module.
Two X.21 connections via X.21 modules with D15 connectors.
Modules are inserted into the rear of the
COMMANDER
G
3
rack unit codec.
You will note in the following image that they are labeled as the left and right
modules.

Important note:
It is only possible to use one 3G or USB module in a codec at
a time. If you insert two modules into a codec then only one will be able to
connect.
