[asterisk-users] BRI card(B800P) doesn's work with DAHDI(wcb4xxp) in NT mode

Wed May 26 22:12:05 CDT 2010

Dear Supports,

I was attempting to install BRI Card(OpenVox B800P) with wcb4xxp in NT mode .But I can not make it worked!

Could you please  give me some hints? Thanks in advance!

Here are my environments:

------------------------------

CentOS-5.3

Kernel-2.6.18-164.el5
asterisk-1.6.1.6

dahdi-linux-complete-2.3.0+2.3.0

libpri-1.4.10.2

OpenVox-B800P(the first port is spliting into two lines, I set the first one into NT mode,and others are TE mode)

patch- manual_te_nt.patch(which download from:http://www.openvox.cn/bbs/viewthread.php?tid=992, and posted by Dmitry)

-----------------------------

I make a fresh OS and yum install all the dependent packages, like bison,bison-devel,gnults-devel,gcc,gcc-c++, and so on.

And download all the same versions of DAHDI-linux-complete-2.3.0+2.3.0, asterisk-1.6.1.6, libpri-1.4.10.2 from asterisk official website:http://downloads.asterisk.org/pub/telephony/.

Completely plugs the card and start to compile and install those packages. Here are my installation steps:

A.Libpri: make-->make install   --(no errors)

B.Patch file /usr/src/dahdi-linux-complete-2.3.0+2.3.0/linux/drivers/dahdi/wcb4xxp/base.c with this method:

patch p0 < manual_te_nt.patch 

C.DAHDI: make-->make install-->make config --(no errors)

D.Edit and insert this line at the buttom of file /etc/modprobe.d/dahdi.conf(only this step is different from yours)

options wcb4xxp te_nt_override=0xFE
E.Start dahdi and automatically configure the channels with: modprobe dahdi-->modprobe wcb4xxp debug=16-->dahdi_scan-->dahdi_genconf-->dahdi_cfg -vvvvvvvvv (no errors and all the channels are showing there)

------------------------------------------------------------------------

Everything seems very good so far as!

F.Asterisk, ./configure-->make-->make install-->make samples --(no errors)

G.As you said before, NT mode with wcb4xxp only supports nt_ptp,and nt_ptmp is not work right now. So I set dahdi-channels.conf like this:

------------------------------------------------------------------------

; Span 1: B4/0/1 "B4XXP (PCI) Card 0 Span 1" (MASTER)
group=0,11
context=from-pstn
switchtype = euroisdn
signalling = bri_net
channel => 1-2
context = default
group = 63

; Span 2: B4/0/2 "B4XXP (PCI) Card 0 Span 2" RED
group=0,12
context=from-pstn
switchtype = euroisdn
signalling = bri_cpe
channel => 4-5
context = default
group = 63

; Span 3: B4/0/3 "B4XXP (PCI) Card 0 Span 3" RED
group=0,13
context=from-pstn
switchtype = euroisdn
signalling = bri_cpe
channel => 7-8
context = default
group = 63

; Span 4: B4/0/4 "B4XXP (PCI) Card 0 Span 4" RED
group=0,14
context=from-pstn
switchtype = euroisdn
signalling = bri_cpe
channel => 10-11
context = default
group = 63

-----------------------------------------------------------------------

and other spans 5,6,7,8 are the same as span 2.

H. After this modification, the dmesg information shows like this:

----------------------------------------------------------------------

dahdi: Version: 2.3.0
wcb4xxp 0000:02:0c.0: probe called for b4xx...

wcb4xxp 0000:02:0c.0: Port 8: TE mode manually set
--------------------------------------------------------------------

Base on this information,it seems that the patch is working, so far so good!

I. Start asterisk with asterisk -vvvvvvvvvvvvgc.and run command "pri show spans", but shows like this:

*CLI> pri show spans
PRI span 1/0: Provisioned, Down, Active
PRI span 2/0: Provisioned, In Alarm, Down, Active
PRI span 3/0: Provisioned, In Alarm, Down, Active
PRI span 4/0: Provisioned, In Alarm, Down, Active
PRI span 5/0: Provisioned, In Alarm, Down, Active
PRI span 6/0: Provisioned, In Alarm, Down, Active
PRI span 7/0: Provisioned, In Alarm, Down, Active
PRI span 8/0: Provisioned, In Alarm, Down, Active
-------------------------------------------------------------------

*CLI> pri show span 1
Primary D-channel: 3
Status: Provisioned, Down, Active
Switchtype: EuroISDN
Type: Network
Window Length: 0/7
Sentrej: 0
SolicitFbit: 0

Overlap Dial: 0
Logical Channel Mapping: 0
T200 Timer: 1000

T308 Timer: 4000
T309 Timer: -1
T313 Timer: 4000
N200 Counter: 3
Overlap Recv: No

------------------------------------------------------------------------

I have plugged the ISDN phone into the first port,and LED is turn to green and not blinking,but when I offhook, nothing dial tone there,and this channel is always under DOWN status.

J. But sometimes it sharply turn to UP status. Under that situation,I was attempting to make some calls from softphone to it, but I can not hear any voice between them(softphone or ISDN phone)

localhost*CLI> pri show spans
PRI span 1/0: Provisioned, Up, Active
PRI span 2/0: Provisioned, In Alarm, Down, Active
PRI span 3/0: Provisioned, In Alarm, Down, Active
PRI span 4/0: Provisioned, In Alarm, Down, Active
PRI span 5/0: Provisioned, In Alarm, Down, Active
PRI span 6/0: Provisioned, In Alarm, Down, Active
PRI span 7/0: Provisioned, In Alarm, Down, Active
PRI span 8/0: Provisioned, In Alarm, Down, Active

Any helps will be appreciated!

Best Wishes!
Michael
