Make sure the codec is powered up.
Check that the cable terminated in an RJ11 or RJ45 connector is correctly connected
and set.
Check the equipment ISDN interface configuration: Menu >> Advanced >> Modules
Config. >> [R] or [L]: Slot ISDN (depending on the slot into which this additional
module has been physically inserted), in both “ISDN Configuration” and “ISDN
Parameters” submenus. ISDN module can be configured in “1 x 128Kbps” mode (to
establish a communication of 128Kbps) or in “2 x 64Kbps” mode (up to 2 simultaneous
communications by assigning each of the two lines to a different channel).
Associate the ISDN interface (“ISDN”, “ISDN L1”
or “ISDN L2”) to the Program or Coordination
channel over which the communication will be
established: “Select interface” in the channel
basic configuration menu.
When the module is configured in “1 x 128Kbps”
mode (it’s shown as “ISDN”) you can only assign
it to Program.
Check communication interface status: blue
background must be shown in the corresponding
indicator in the up-left (Program) or up-right
(Coord.) corner on the TFT screen.
Select the enconding mode: “Sel. codec" in the
channel basic configuration menu. The available
modes vary according to the selected channel
and the ISDN module configuration (see section
1.3).
Select the communication destination (by
manually introducing the number or by selecting a
contact from the phone book): “Call to” and “Select contact”/”Enter number” in the
channel basic configuration menu. When the ISDN module is configured in “1 x
128Kbps” mode, 2 numbers will be introduced.
Press the green button on the control surface to launch the connection (the progress of
the communication establishment process is displayed in the upper area of the TFT
screen).
Once the connection has been correctly established, the LED
next to the transmission button corresponding to the used
channel (Program or Coordination) will remain green-lighted.
Activate the channel communication circuit by pressing that
button (it will light up on red).
It’s possible to change the encoding mode while the connection is established. It can be
done, by changing the selection in “Sel. codec” section in the channel basic
configuration menu. You must select the same mode in both units in order to get a
correct synchronization.
5.6.1. Ending an ISDN communication.
•
To end the communication, you need only to press the red button on the control
surface. At the other end of the communication, the call will be automatically terminated.
