Your provider should give you 3 informations.<br>
<br>
His pointcode (adjacent pointcode in your config)<br>
Your pointcode (pointcode in your config)<br>
and eventually a default pointcode if they are other hops between you
and him (usually you will use the adjacent pointcode).<br>
<br>
Maybe, we can say that it works like IPs (your Ip, his Ip, and
eventually a proxy).<br>
<br>
Noob answer, that's how I understand things :)<br>

<pre wrap="">As a newbie myself I was wondering if someone could tell me the difference
between the pointcode the adjacent point code and the defaultdpc. I am
trying to obtain these infos from my carrier but he is only giving a single
point code.

<pre wrap="">Hi
Thnks for the reply...So say if i want 120 channels over ss7
signalling...will the telco give me 4 E1s and 1 separate E1 for ss7
signalling or will the ss7 be in one of the 4 E1s itself..?

<pre wrap="">Sometimes. It depends on what you negotiate with the telco you're
interconnecting with. Some of them like to waste an E1 on a single
signalling link though. And even stupider ones waste a single E1 on
two signalling links. It seems ridiculous to mandate redundant
signalling links and have them running over the same E1 (Don't ask,
I had somebody come to me having to deal with that).
But in any case, you can negotiate with them how you would like to
set it up typically.

<pre wrap="">If you need answers to that question, you probably need to research
more into what SS7 is.
Typically, you have a more reliable link since you can have
redundant signalling channels. The protocol also supports a lot
more bearers per signalling link than you can do in PRI (or even
NFAS PRI).
