I'm not 100% sure I'm correctly understanding these latter two questions. Anyway, refering to http://en.wikipedia.org/wiki/Integrated_Services_Digital_Network / Basic rate Interface paragraph, my setup includes : - a single network termination unit, installed and managed by telco, is connected to public network through 2 twisted pairs, - this unit includes two small electronic cards, - each card has two RJ45 sockets, - each card is connected through a single Cat5 straight, 1m long patch cord to a single BRI port from my Patton box, - both Patton's BRI ports are managed as a "hunt group" (for outbound calls), - for inbound, I didn't checked but usually, Telco sends one call on one interface, the next one and the next interface. So to summarize, (I think): - I'm getting ISDN signal from two distinct copper pairs, - it is not an S0-bus. > If yes, I may be able to be of further help. Even if the connection goes > down, it should not matter for P2MP connections. You mean: layer1 is down but layer3 remains up ? I'm seeing layer3 going down for 4 or 5 seconds, then up again. This happens for both interfaces. > But S0-bus problems can be nasty (though seen rarely these days). > > >> So, if I'm not mistaken, either : >> - these lines are configured as P2MP (and not as P2P as required), >> - I'm facing something else I've never met before. >> > I would bet on the 2nd choice. >From memory, with a misconfiguration between P2P and P2MP, you get no call at all which is not the case. > > >> As these lines are up most of the time, I'm having a hard time to get any >> useful help by Telco beside "level 1" basic checks. >> >> For the record, these lines are terminated on my side with a Patton >> smartnode (most of the time, I use Digium BRI boards). >> During off hours, I'll try to check what happens when toggling to P2MP >> mode. >> > I doubt that you do get anything useful if you pick the wrong mode. > > Are you sure that your are not dealing with termination issues? > Try sending a T.30 fax with fine resolution and ecm enabled when your > connection is up.

I'm using an old Asterisk 1.6.1 version there so I can't rely on T.38/T.30 gateway feature at the moment. > > > jg > > > -- > _____________________________________________________________________ > -- Bandwidth and Colocation Provided by http://www.api-digital.com -- > New to Asterisk?
