Darren,
Many thanks for your help - I've got further, but am still stumped. Have a look at the following table:
LED | ISDN | Asterisk ------+-----------+--------- OOS | Out | Red ACT | Green | Green RED | Out | Red YEL | Out | Out LBK | Out | Out CC | Out | Out DCH | Green | Green
The LED indicators are as follows:
OOS: Out of Service ACT: Active State RED: Red alarm state detected (Could be Loss of carrier, loss of frame or loss of crc multiframe YEL: Yellow alarm state detected (remote alarm indication from remote end) LBK: Loopback mode CC: Clock controller not equipped DCH: DCH is established.
What this table indicates is that if I plug the 2MB pri card from the nortel into the EuroISDN bearer box, the leds light up as shown in the ISDN column. If I plug the nortel card into the asterisk box, then the leds light up as shown in the Asterisk column.
I would have expected the leds to light up in the same manner - am I missing something ? Apart from asterisk experience :)
Couple of things to look at: 1) Darren's config assumes you have plugged the _whole_ thing together ie PSTN->*->nortel ie 2 e1 connections - your table above implies that you are doing one then the other. This won't work because the config tells * to get the timing source from the PSTN. 2) I've _never_ had any luck using crc4, I always turn it off and only put it back if someone complains. 3) If you have been struggling for a while you may have strayed onto the telco's 'badboy list'. I have one installation where I misconfigured it once and they marked the interface as 'down' at the exchange. Nothing worked untill I rang them, whereupon they marked it as 'up' and things started working (once I'd fixed the config).

Hi Julian,
J> I want to put asterisk in the middle of our current pbx (Meridian J> Option11)
Something like this?:
--------------------- | | PSTN <---span1--| CPE Asterisk NET |--span2---> Nortel | | | | ---------------------
Assuming that you connect your incoming Telco PRI (PSTN) to span1 and the Nortel PBX to span2 (as depicted above) the lines below should help:
Extract from zaptel.conf ========================
span=1,1,0,ccs,hdb3,crc4 bchan=1-15,17-31 dchan=16 span=2,0,0,ccs,hdb3,crc4 bchan=32-46,48-62 dchan=47
Extract from zapata.conf ========================
pridialplan=local switchtype = euroisdn signalling = pri_cpe
group = 1 channel => 1-10 switchtype = euroisdn signalling = pri_cpe
group = 2 channel => 32-41 switchtype = euroisdn signalling = pri_net
In the config lines above, span1 is set to take timing from the PSTN whilst span2 is configured to "give" timing to the Nortel. Span1 will behave like a piece of CPE (PBX) and span2 will behave like the NETwork. NB. The channels in group 1 and 2 are depleted as you only have 10 channels enabled on your PRI.
After you have implemented the changes above (or any subsequent changes to the low level PRI config) you should, at the very least, remember to restart the Asterisk system or, as Critch advises, power down and up again.

I've googled / voip-info'd / searched until my eyes are blurry, but couldn't see the info I was looking for. I've turned here for help!
Asterisk CVS head (9/7/04) Fedora Core 2 (updated to 2.6.6 kernel) DE405P (jumpers set to E1)
I want to put asterisk in the middle of our current pbx (Meridian Option11)
Currently the meridian has a 2MB pri EuroISDN card linked via a rj-45 into a euroISDN bearer. This bearer only has 10 channels activated (out of the 30). Obviously, this works - handsets make external calls.
What I wanted to do was to add * to the mix, in the middle so that it can intercept inbound / outbound calls and do what it needs to do, as well as providing all the extra functionality that this wonderful product provides.
In order to achieve this, I assumed that I needed to take rj45 from the bearer box and plug that into span 2, and take a cable from span 1 into the bearer box.
My problem (and blurry eyes) come from not understanding the various protocols to assign to each span. I want the meridian to think that it's still plugged into the EuroISDN bearer. So span 2 should be set up as a EuroISDN link ? What should span 1 be set up as ? What channels should be configured ?
Any guidance (I'm not looking for the solution (would be nice!) but for pointers in the right direction).
I have previously been able to set up asterisk using the x100p and graduated to BRI isdn. I just got the 405 today and wanted to play!
Thanks in advance.
Julian.
