UK PSTN Settings for TDM400P - FXO ??

Hi All,

Having played about for a while with an old winmodem card I decided it was time to invest in a proper Digium board.

I installed the card, booted the machine then ran

genzaptelconf -s

Happilly, the card was recognised first time.

However, a review of the DMESG log shows:

<snip>
Freshmakehmaker passed register test
Module 0: Installed -- AUTO FXS/DPO
Module 1: Installed -- AUTO FXS/DPO
Module 2: Installed -- AUTO FXS/DPO
Module 3: Installed -- AUTO FXO (FCC mode)
Found a Wildcard TDM: Wildcard TDM400P REV I (4 modules)
</snip>

Now its been a few years since I worked on PSTN exchanges (17+ years in fact!) and I recall that although exchange battery is -48V (-54.6v on an AXE exchange for the pedants out there ) , FCC levels of AC ring voltage are somewhat below the 80V AC used by BT (ISTR it was 50-70V AC ?)

Therefore I'm a little reluctant to plug my shiny new card
into the BT socket "just yet"

Presumably, I need to "Hand edit" the appropriate parameters
in one of the /etc/asterisk/zap*.conf files...but which parameters ? theres no "TFM" to "R"

Also I see my tones are set for region 0 (USA) , where / how do I set them for UK / Europe please ?

All salient URLs / info greatly appreciated!

[EDIT] forgot to add

tried genzaptelconf -d -s -c 44

to no avail

Oh ***** !

it IS (in my defence) > 2am here

answer to one part found !

genzaptelconf -d -s -c uk

But dmesg now shows:

Freshmaker version: 73 Freshmaker passed register test Module 0: Installed -- AUTO FXS/DPO Module 1: Installed -- AUTO FXS/DPO Module 2: Installed -- AUTO FXS/DPO Module 3: Installed -- AUTO FXO (FCC mode) Found a Wildcard TDM: Wildcard TDM400P REV I (4 modules) Registered tone zone 4 (United Kingdom) usb.c: registered new driver wcusb Wildcard USB FXS Interface driver registered Registered tone zone 4 (United Kingdom) Registered tone zone 4 (United Kingdom)

so still looking for an answer to the "FCC" part

I'm by no means knowledgable about asterisk, only been playing with it for about a month but it seems to be about the way the module is loaded. I'm using asterisk@home and have the following:

Module 0: Installed -- AUTO FXS/DPO
Module 1: Not installed
Module 2: Not installed
Module 3: Installed -- AUTO FXO (UK mode)
Found a Wildcard TDM: Wildcard TDM400P REV I (4 modules)
Registered tone zone 4 (United Kingdom)
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb.c: registered new driver wcusb
Wildcard USB FXS Interface driver registered
Registered tone zone 4 (United Kingdom)
Registered tone zone 4 (United Kingdom)

It appears to be the way the module is loaded, this works for me with a 2,4 kernel:

[root@asterisk1 etc]# more modules.conf
alias eth0 e100
alias sound-slot-0 i810_audio
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1
|| :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 |
| :
options torisa base=0xd0000
alias char-major-196 torisa
post-install tor2 /sbin/ztcfg
post-install torisa /sbin/ztcfg
post-install wcusb /sbin/ztcfg
post-install wcfxo /sbin/ztcfg
post-install wctdm /sbin/ztcfg
post-install ztdynamic /sbin/ztcfg
post-install ztd-eth /sbin/ztcfg
post-install wct1xxp /sbin/ztcfg
post-install wct4xxp /sbin/ztcfg
post-install wcte11xp /sbin/ztcfg
post-install pciradio /sbin/ztcfg
post-install ztd-loc /sbin/ztcfg
post-install ztdummy /sbin/ztcfg
alias wcfxs wctdm
options wctdm opermode=UK

HI

The basic settings for UK working are

/etc/zaptel.conf
make sure the following are as below

loadzone = uk
defaultzone=uk

and in /etc/asterisk/zapata.conf

for CLI to work

cidsignalling=v23 ; Added for UK CLI detection
cidstart=polarity ; Added for UK CLI detection
Immediate=yes ; as we recieve cli info before not after first ring.


Hope that will help.

Ian

Hi Chaps,

thanks for the feedback

DigitalDaz:

presently running a 2.4.21 kernel *@home distro on a P2 500
my modules.conf is certainly different to yours, and was missing the line:

options wctdm opermode=UK

It now looks like:

Code:

alias eth0 3c59x alias usb-controller usb-uhci options torisa base=0xd0000 alias char-major-196 torisa post-install tor2 /sbin/ztcfg post-install torisa /sbin/ztcfg post-install wcusb /sbin/ztcfg post-install wcfxo /sbin/ztcfg post-install wctdm /sbin/ztcfg post-install ztdynamic /sbin/ztcfg post-install ztd-eth /sbin/ztcfg post-install wct1xxp /sbin/ztcfg post-install wct4xxp /sbin/ztcfg post-install wcte11xp /sbin/ztcfg post-install pciradio /sbin/ztcfg post-install ztd-loc /sbin/ztcfg post-install ztdummy /sbin/ztcfg alias wcfxs wctdm alias wct2xxp wct4xxp options wctdm opermode=UK

for the benefit of people following in my footsteps the UK needed to be in uppercase. Fortunately DMESG moans at you
about it and gives a verbose geography lesson

but now dmesg |grep Module

gives:

Module 0: Installed -- AUTO FXS/DPO
Module 1: Installed -- AUTO FXS/DPO
Module 2: Installed -- AUTO FXS/DPO
Module 3: Installed -- AUTO FXO (UK mode)

Thanks for your contribution too! all the tones sound correct now, the only thing that sems a "little" odd is that the FXO port seems a little quiet - that could be me though! touch of bronchitis keeps "popping" my ears of late

Regards & Thanks again.

Hi

As to the volume, Have you run ztmonitor and set the levels ?

Ian

not yet

next job methinks !

Regards

BB

[edit] hmm...only ztmonitor is in /usr/src/zaptel
command not recognised better compile it [/edit]

Can't seem to get mine to go to uk mode. Can you tell me where you insert the line?

options wctdm opermode=UK

Did you manage to figure out why the volume was so low? I must say I get better quality comming over IP than I do from using the card.

Hi

What OS are you running? as its dependant on OS.

Does you asterisk auto start ? and do you have any other cards.

Ian

I'm running CentOS release 4.1 (Final)
Kernel Version 2.6.9-11.EL
and yes it does auto start, but I can't find out what version of asterisk I'm running

Hi

Thats a 2.6 kernel isnt it ? from my notes you need to add the line to the modprobe.conf file

Code:

install wctdm /sbin/modprobe --ignore-install wctdm opermode=UK && /sbin/ztcfg

see if that does it. if it doesnt then the you need to add the options line to /etc/modprobe.d/asterisk

Ian

Thanks, I'll try that when I get home tomorrow. Can you give me a clue to where the file is located?

Boy it's a steep learning curve on this product. Just when you think it's all a piece of cake, something else pops up to bite you. Still todate, they're slowly getting resolved one by one.

Hi

Ok

from the linux promp

find / -name file_name_you_want

Ian

tried it and this is what I got

Looks like it did the trick, thanks

Issue I have now is,

Call fixed line number, phone rings for a few times, then * picks it up and rings extension.

Issue 1. Why 3 rings before inbound call detected by *?

Issue 2. If I hang up after handover to *, extension keeps ringing until it goes into voicemail. In otherwords a hangup detection is not happening. Line is only put back on hook when voicemail silence period expires? I'm beginning to suspect these cards aren't really suitable for UK PSTN use.
