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

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.

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..?
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.
Do i have to just plug in those 4 E1s directly into the TE420P and
install libss7 ? thats it ?
Yes :-) And configure it.
Also please tell me what are the advantages of ss7 over PRI in terms of
1.call handling capacity 2. connectivity 3. reliability ..
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).
