PRI, DID & Target Lines 1

[txnorstartech]

I have a MICS 4.1 with NAM.
System has PRI with DID's riding.
out of the 100 DID's about 6 of them ring no answer.
I have double checked the Target lines assigned to them under "Lines" & "Terminal & Sets"/line assignment.

I am sure I am missing something. System has been running fine for about two years with no problems. Now all of a sudden these 6 DID will not ring on the set. Also if intercom dialing these ext's the system says "not in service".

Any thought anyone?

Besides re-setting the system & re-programming?

Has the system took a hit,Have you check port to dn, is set relocation on has some or many ext been move.. Sounds like you are doing things right, But i would check ports to your dns,and if all is right call telco to check the 6 numbers
its not century tel is it. They have some pour eng....

Justatec has the right idea,it looks like ports. Rebuild the sets on another port, different extension and test.

Reassign the target lines to a new test set on another port first. To test the PRI telco can put a Tbird on and check receive digits to verify.

From what I can tell the system has not taken a hit. The only thing that is weird is that some of the target line are duplicated to TN's.
So I straighten that out so far but no effect on the affected DID's. SBC has double check the translation on the PRI but getting them out with a T-bird seems to be impossible even though I have requested the visited the vendor meet.
I tried the swapping of ports as well but no change.

I am just not ready to restart as of yet.

Whats your Numbering plan, What did ypu start at,,I had a BCM which i changed the Starting DN and it messed up some or it wouldnt let me start with 421.. So i started with lower and then changed DNS,

Since it is a PRI DID and you are getting a ring back (Ring no answer) that is an indication that you have accepted the digits from telco and are returning ringback from your system. (tech meet probably won't help).

you can verify this by removing the received digits from a target line that you know works and dialing the number, if you don't have a number programmed you should get silence on the line only. now you can try the same thing from the target line that has ther trouble and verify that you are working on the target line that is handling the incoming call. at this point you will be positive that the call is coming into the phone system and you can start into figuring out the ringing of the target line.

do as jerryreeve suggests, this will prove that hte call is coming into the norstar.

there are cases when the numbers are 'stolen' - meaning reallocated to someone else

Well guys this is a first I had two flaky station modules. I replace both yesterday.
I have never really seen a station module go a fraction bad. Nothing in trouble shooting would have indicated the station module.
In trouble shooting yesterday, the only thing in common with the 5 lines were the two mod's so I replace both.

I am still having problems with one line. (fax) line
