[Asterisk-Users] Connecting quadbri to EuroISDN with 2 TE and 2 NT ports - what cables and settings ?

[Robert Rozman]

Hi,

I'm trying to connect quadbri between powered ISDN phone and ISDN line:
ISDN <---1--->  TE - * - NT <--2--> Phone

I use quadbri, suse 9.2 and latest 0.2.0-RC7k bristuff. I've used sample 
settings provided with package, but do get strange error (I think that I 
have wrong setting for P2P or P2MP setting and cables 1 and 2).

If I connect phone to ISDN with straight cable it works. I've put quadbri in 
between, and connected ISDN to span1 in TE mode, and phone in NT mode on 
span4. Did configuration (added at the end). I get errors:

qozap: CRC error for HDLC frame on card 1 (cardID 255) S/T port 1
qozap: CRC error for HDLC frame on card 1 (cardID 255) S/T port 1
qozap: CRC error for HDLC frame on card 1 (cardID 255) S/T port 1
qozap: CRC error for HDLC frame on card 1 (cardID 255) S/T port 1
qozap: CRC error for HDLC frame on card 1 (cardID 255) S/T port 1
qozap: CRC error for HDLC frame on card 1 (cardID 255) S/T port 1

I'm not sure what cables to use. I use straight for -1- and -2-. Is this 
right ?  I'm in European community (EuroISDN) so I guess I should have some 
pretty standard connections...

I have ISDN line with 2 MSNs and two connectors on NT termination - so I 
guess this is P2MP. Is this OK ?

Does anyone have working example for Germany ?

There is also one strange thing: I get this in dmesg when loading qozap 
module, although I have specified 4th port to be NT - and pri show span 4 
shows it in netowork mode:

Zapata Telephony Interface Unloaded
module zaptel unsupported by SUSE/Novell, tainting kernel.
Zapata Telephony Interface Registered on major 196

qozap: S/T ports: 4 [ TE TE TE TE ]
qozap: 1 multiBRI card(s) in this box, 4 BRI ports total.

Thanks in advance,

regards,

Rob.
