asterisk users - Aug 2004 - QuadBri in NT mode not working.

I am unable to make quadbri board to work in NT mode, in TE mode it works
OK. I have set 5 jumpers to NT mode. Dmesg shows everything OK:

qozap: Junghanns.NET quadBRI card configured at mem 0xd084e000 IRQ 9 HZ
100 CardID 1
qozap: S/T ports: 4 [ TE TE TE NT ]
qozap: 1 multiBRI card(s) in this box, 4 BRI ports total.

from Asterisk side seems to be ok.

Using Stright cable ( do hope that board croses pins with jumpers).
But niver small lucent PBX indicates link, niver ISDN Courier I modem
connects to board.

Has anybody idea were to dig?


Configuration looks like:

cat /etc/asterisk/zapata.conf

[channels]
switchtype = euroisdn

signalling = bri_cpe_ptmp

hidecallerid=no
usecallerid=yes
callerid=5555

channel => 7-8

group = 2
signalling = bri_net_ptmp
channel => 10-11

Hi,

I have pretty much the same setup here and am able to connect to an AVM Fritz!X
USB (1xBRI, 4xAnalogue) and a TelesFON ISDN phone.

Are you use the "power" module which is an additional purchase to
provide power to the NT bus?

Straight through cable is good

I do not incect power to the board.

As far as I understand the power supply needed when you connect bri card
to phone without external power supply.
But my both devices use external power supply. small Lucent PBX uses
external power supply of cource.

So does the Fritz!X, but it doesn't supply power to the ISDN bus...
(Probably uses the external power to drive the ringer on the analogue
extensions)
