Hello,
It's a good news that you have solved that problem which relates to NT mode with dahdi. If possible, welcome your descriptions of how did you make the card worked in NT mode with dahdi driver.So that it's able to share with other users. Thanks in advance!

Regarding to the cable, actually I don't understand the exact means of "Anyone know how must see cable to connect this ???" Would you mind talking more about it ?

If you want to connect the ports which one of them in NT mode and another in TE mode, firstly , you need some spliters(see this: http://www.openvox.cn/products/list.php?catid=42&lang=2 , SP124), and plug them into the corresponding ports that you have specified. And the pins oder should be: 3,4,5,6<-->5,6,3,4.

Ok I was tested and now I try make solution but my eng is low and it will be hard to understand.

info of hardware what been used:
-.HP PROLIANT 580 4xCPU 2.8 XENON MP 4096MB/RAM
-system slackware: 13.0 32bit,

verisions: Asterisk 1.6.1.6, DAHDI 2.3.0,libpri 1.4.10.2

1. Download:asterisk, dadhdi,libpri.
2.make,make install libpri.
3.patch file ---src---/dahdi-linux-complete-2.3.0+2.3.0/linux/drivers/dahdi/wcb4xxp/base.c
patch is here http://bbs.openvox.cn/attachment.php?aid=162 and is write by "dimitri".
4.make ,make install dahdi
5. edit /etc/modprobe.d/modprobe.conf
insert "options wcb4xxp te_nt_override=0xFE"
(if you want like 1 port NT and else port TE, if you want else that you should change parametr 0xFE).
before you must set jumpers on card to work 1 port nt mode.
6.modprobe wcb4xxp
7.dahdi_scan
8.dahdi_genconf
9.dahdi_cfg -vvvv
10.configure make make install asterisk.
11. asterisk -vvvvc and see pri show span 1 , is as NT mode.
Imporotant is that you can use only nt_ptp mode, nt_ptmp is not supported right now.

Joe Young you cable is wrong, in case b800P card I was used srtight cable because when you change jumpers then pin of this port will change.
On hardware pictrue in manual (parts of make cable) is everything explain.

Hello Czelusc, Thanks your great installation steps firstly.


Yes, you are right, The cable that I described above(3,4,5,6<-->5,6,3,4) was not match your case here(It's B800P here). The correct method was using straight cable instead of the cross one. Sorry for my foolish fault!
