I have piggy backed a few PBX's off the back of a B410P (4 x BRI) card with no problems. The ones I used for testing were the Avaya IP Office, Siemens Hi-Path/Hi-Com and various old Panasonics.<br>
<br>
All I had to do was to turn on the 100ohm termination on my S0 ports (set as NT on the B410P of course).<br>
<br>
I actually have a similar set-up at the moment on our main asterisk system. 2 x BRI trunks (ports 1 & 2 set as TE ptp - for the DDI's etc) and 2 x BRI S0 bus (ports 3 & 4 set as NT ptmp) running and ISDN modem on each (good old Fritz! ones).</blockquote>
<div><br>Fine, so, using this setup as an example, would say the norm in the UK, is to connect to ISDN-BRI in ptp (reading from ports 1 and 2 configuration), or to connect using ptmp (reading from ports 3 and 4 configuration, dedicated to isdn modems) ?<br>

<br>
So it is possible to run ptmp on NT ports using mISDN - just remember to turn on 100ohm termination on the ISDN card if you only have one device per port.<br>

Hello Andrew,<br>
2008/12/17 Andrew Thomas <<a href="mailto:andy@datavox.co.uk">andy@datavox.co.uk</a>><br>
If you are connecting to BRI lines then you should be TE - not NT.<br>
<br>
Yes of course, you're right.<br>
<br>
I was mostly referring to this :<br>
ISDN ------<BRI> ---- asterisk -----<BRI>----- legacy PBX<br>
<br>
Then, in this case, as legacy PBX has a set of TE-PtmP or TE-PtP interfaces, asterisk box should also include such NT-PtP or NT-PtmP interfaces.<br>
<br>
For instance, would you say that in the UK, most PBXes are using TE-PtP ?<br>
<br>
<br>
You can run as TE ptp or ptmp with mISDN (not sure about DAHDI yet - not tried the new release).<br>

Subject: [asterisk-users] libpri and NT-Point to multi-point<br>
<br>
Hi,<br>
<br>
At the moment, libpri /w Asterisk 1.6, Dahdi 2.1, is not supporting NT-Point to multi-point mode.<br>
Here (France), most small PBXes are connected to ISDN through BRI trunks in PtmP (don't know why but it seems the general case).<br>
So this NT-PtmP function would be very helpful to easily slide an Asterisk box between an existing PBX and the network.<br>
<br>
Does the same case apply elsewhere (UK, Germany, Italy, ...) ?<br>
Do you think this is needed ?<br>
<br>
Regards<br>
