27.1.
Select ISDN Interface
This drop-down menu allows the user to select the
ISDN module you are configuring. To select the
ISDN connection you want to configure, simply
click on the right-hand arrow, highlight the desired
connection and click on it to select it. Once you
have selected the module you can then view and amend the following settings as
required.
Please note:
Depending on the codec you are using, this menu will display
slightly differently. The preceding image shows a right-hand ISDN module. An
i

Mix
G

will only display this module option, whereas a
COMMANDER
G
3
codec
will display a left and right-hand module because there are two module slots in
these codecs.
27.1.1.
Bonding Four ISDN Channels Using Two ISDN Modules
As previously mentioned,
COMMANDER
G
3
codecs have two module slots
available and it is possible to bond up to four ISDN B channels together,
using two ISDN modules, to increase the connection bandwidth available for
a broadcast.
To program the SPIDs and DNs etc for each module, simply select one
module at a time in the
Select ISDN Interface
drop-down menu and enter
the relevant information for each modules B channels. Once you have
programmed both modules you will need to enter the ISDN number for each
B channel in the
Connection Setup
tab within the
Profile Editor
.
27.2.
ISDN Network Type
You will need to select the
Network type
in your
codec that corresponds with the region in which
you are using your codec. To select the network,
click on the right-hand blue arrow in this menu to
reveal a drop down menu and highlight the
network you require – click it to select it.
The list of possible networks that can be used with an ISDN module in
G
3
codecs
is shown in the following table. It will assist you to decide which network type you
need to select and program into your codec. If you are in North America, you
need to ask your phone Company for the switch type. In other places, EU-ETSI
most probably will work.
27.2.1.
ISDN Interface for North America and Other Regions
If you are using your codec in North America, it will most likely be connected
to an ISDN line with a two-wire ‘U’ interface. You will need to have a ‘U’
interface ISDN module installed in your codec to use this type of line.
