6.5.1.2 Testing the card and the physical connection

For testing of physical connection we can use Minicom or another program with similar

functionality. After start of Minicom isdn0 (nowadays you have to use Minicom -s isdn0) we

have to setting port (ctrl-AO), /dev/ttyI0 as the device. For modem we can set init string

AT&E6130578, which define MSN, Speed to 38400 or whatever; it doesn't really matter, as the

speed will be 64kb/s anyway. Last save these settings and chose exit (not exit Minicom ).

Minicom will now initialize the "modem", and then connected it to the ISDN modem

emulator. We can try to write AT commands. If we put AT we should get a response OK. The

ATI1 command return device Information ("ISDN for Linux...") or AT&V show current

With ATD<number> we can test to call specified number. If we don't see RING, then

maybe we have to enter the number with areacode.

If in the screen was we entered ATD you see BUSY appear, then a number of things may be

wrong; unfortunately most failures are simply indicated with BUSY (only when there is no

physical connection working do you see a different message, namely NO CARRIER).

If BUSY appears after 1-3 seconds, then the message may be right, and the remote number is

in fact busy. However, if it takes longer, then probably something else is the cause of the

problem. Look in the system log messages for hints.

6.5.1.3 Configuration ISDN connection in PBX (modem.conf)

For ISDN (BRI) we have the device: /dev/ttyI0 so we will have to add it as well -

modem.conf. Most likely you will define a group like "g1" to include all ISDN channels. In

extensions.conf we probably want to define g1 as trunk: TRUNK=Modem/g1.
