DID nightmare

[hondacrusher]

Thought I would post this here as SBC and our local line provider keep pointing fingers at each other. First of all I will set this thread up with what the customer has. Bare with me I am an AVAYA communication technician, I know very little about Nortel/Norstar plus modular ICS phone systems. They are setup with the following. First cabinet is the Nortel Applications Module, Second cabinet is the Norstar Plus Modular ICS (Slot 1 OPEN, Slot 2 Combo, Slot 3 DS card), Third cabinet is a M12XO (slot 1 - DS, slot 2 - DID, slot 3 - DID)

Other information about this system that I wrote down is the Target line is L145.

Amphenol #1 has CO49-52 and CO57-60, this is connected to the M12XO carrier and has 4 DID's cross connected to CO 57-60.

Amphenol #5 has CO1-4 and CO25-28, this is connected to the middle cabinet and has CO3, CO4, and CO25-28 are cross connected.

I did testing with SBC on the phone. If I clip onto the 4 DID trunks at the 66 block and go off hook, my red led is on, switches to green, then back to red. They tell me this is the wink. I can then dial the last 4 digits of the main number here on site and get to the receptionist or whoever answers the phones.

Here is the main problem. If I dial their main number which is a DID and the receptionist answers, she is talking to me or puts me on hold, if another call comes in on that same DID # it rings busy. Now I have been told that if that is busy it should ring the second DID trunk but it doesn't. I just get a busy signal. This customer can only recieve one call at a time with their main published number. The local phone company tested the wiring, says its good. The line provider says they are not seeing a wink on the first 2 trunks. This has been happening for 4 weeks now!!! I went through this entire phone system with SBC, replaced both DID cards and still have the same problem. What is the problem here???? Has anyone ran into this before???? SBC tells me they are 98% sure it is a line provider issue. Any help would be greatly appreciated. What can I tell the line provider or what tests can I do to prove it's their problem?

Is the prime set for the target line for the main number set for the DN of the receptionists phone? There should be some options in the target line settings, such as 'If Busy - To Prime' or 'If Busy - Busy Tone'. If it's set to prime, make sure that you have a valid extension in the prime set field.

Also, make sure that you are assigning target lines to ring on the set, and not the physical DID trunks themselves.

The system is set for "if busy - to prime" I do remember them walking me through that part. The extention they have in the prime set field is the receptionist phone. The last 3 digits of the main number here is her ext #.

One other thing, probably not related, after turning the power on I did see an alarm come up on the recp. phone that said Alarm 50-04. If anyone knows what that is let me know. Thanks a lot!

If I read your post correctly then this is an SBC issue. If a call comes into the system across DID trunk 1 and the call is answered, then that Trunk becomes busy. The CO is the originator of the call and is the master control. If another call comes in on the same #, it is the SBC's COs responsibility to route that call to the next available DID Trunk through hunting or whatever. I don't think the CO should wait for a wink from the system to route the next call.

How many appearances of line 145 do you have assigned to the recp't phone?

 

[NorstarWiz]

How many intercom buttons do you have assigned also? If you only have 1 appearance of the main target line or the line set to ring only, the call goes to the intercom path. If you only have 1 assinged this could be the issue.

Polarity has played havoc with SBC and BellSouth on several installs. Be sure and check this.

Make sure the reception phone is not set to DND on busy.

It sounds like norstarwiz has his finger on the problem. either increase the number of line appearances on the reception set or set it to ring only and increase the number of IC appearances on the reception set.

They have 5 Intercom buttons.

SBC's technical support says the system is programmed correctly. I also talked to a guy that knows a ton on these systems and he even told me everything is fine with programming. I will be checking in with the line provider tomorrow on what they can do next. Is there a way for SBC or any technical support people to dial into the system remotely? I did notice they had a "fastrad". Would that be what they use to get into the system? Thanks to everyone for responding with ideas on what to check. I think my next step is to have technical support dialed into the system and conference them on with the line provider so they can figure something out. On a brighter note, I worked on yet another nortel today, everything went well!

You have to set the fastrad's acess code in the system, and set it to answer a line, then it can be accessed remotely for programming. With a fastrad in place, they propbably have already programmed it.

I think you're going to find that your ILEC doesn't have their translations programmed correctly for the PRI

Just thought i'd follow up on this. The line provider had two DID trunks coming into the building with reverse polarity on the tip and ring. This caused the entire trunk to not work at all. Line provider kept saying it was the phone system but it wasn't. Thanks to everyone that posted their help and ideas on this thread.
