ISDN
This menu allows users to configure ISDN connection settings within
T
ieline
codecs.
(Please note: Even if you don’t have
Tool
Box
software connected to your codec,
these functions are available by accessing your codec menu via
SOFTKEY 4 Menu
.
Next select
Configuration
and select the ISDN connection you wish to configure.
Now scroll through the menu and adjust the settings you wish to change. See the
Configuration menu diagram for details of this menu structure.)
Each
T
ieline
codec can provide mono or stereo capabilities using a single B channel.
In addition, if you have 2 B channels available, you can use one as a standby or
operate in stereo, dual mono or mono IFB modes.

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. 256 kbps connections can be
achieved using this method. This is particularly useful when using MPEG algorithms
for broadcasts.
In order to use a
T
ieline
G

codec in ISDN mode you must insert either one or two
ISDN plug-in modules and configure these modules by programming the following
information in the
ISDN
setup menu.
Important Note:
ISDN connections will always appear as available on the codec
because some networks are ‘on-demand’ and need to detect a valid network. These
networks will not send you ISDN sync information until an ISDN connection is
detected. If you try to dial an ISDN connection and the line is not connected, the
codec will display
No signaling data. Check wiring
