[HELP PLEASE] Digium PRI Card & FXS

Hi there,

I’m trying to get a system installed that has one Digium TE110P and a TDM10B on Trixbox.

So far i have been able to get the ISDN up and running, but i am having a problem configuring the TDM10B. The card has power and the analogue phone connected to it is giving me feedback (i can hear myself when off hook) but i cannot get a dial tone.

whenever i try and configure my zapata.conf file and restart asterisk it refuses to come up (asterisk that is).

I do not believe that this is an IRQ issue, the output of the relevant section of my lspci is below:

[quote]
03:01.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface
03:02.0 Communication controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface[/quote]

This is my zaptel.conf:

[quote]
loadzone=uk
defaultzone=uk

;fxoks=17

span=1,1,1,ccs,hdb3,crc4
bchan=1-15
dchan=16[/quote]

the fxoks section is commented out because asterisk wont load with it. I did try and set it to fxokx=4 (the fxs module is on the 4th slot of the card) but zttool was giving me conflicts.

below is my zapata.conf

the channel variable is commented out because asterisk jsut wont start with it.

i suspect that i have not quite got the grasp of channel allocation and that to someone that is much more advanced than i am this is a simple fix. So with that please accept my thanks in advance for any help you can provide.[/quote]

Where are the other 15 channels defined ?

you should define all channels in zaptel.conf

hi and thanks for your reply.

the actual line that is going in will only have 8 channels and it seems to work fine on a system with a single pri card and nothing else.

nevertheless i added provision for the other 15 channels and it does not seem to have helped much unfortunately.

the zaptel.conf looks like this now:

[quote]loadzone=uk
defaultzone=uk

fxols=1

span=1,1,1,ccs,hdb3,crc4
bchan=2-16,18-32
dchan=17[/quote]

try reversing the channel numbers. PRI 1-32, TDM 33-36.

i’ve never mixed Digium cards this way, but it’s how i setup Sangoma installs (albeit the cards are reversed, FXO/FXS first, then PRI)
