The PBX would provide clocking for you because one of his T1s should be programmed in the PBX to take clocking from the CO and all other T1s would clock off that one.

Yes, there is a test for slipping. Have him type "test board <your DS1 board>". He can cancel the test after test 146 finishes because the rest of the tests are for the individual channels. You are interested in test 144, that test is a slip counter and will show the number of slips since the last time the test was run. It resets to zero each time it runs.

The first time it runs there will probably be some slips, test the board again and it should pass. If not, then there is slipping between you and him. Do the rest of the tests pass? If not, that might be the cause of the slipping.

His reply when i asked him to test the board was simply
"Are system is opened up enough to test boards."

I assume he meant isnt but I'm not really sure where to go from here, I suppose their line provider and see if they would know the information I need for the bit signaling to pick up the call. Any other suggestions or ideas?

It sounds like he does not have maintenance commands available. Have him type "display sync" and see if it shows a sync source other than 1A. Without maintenance commands there is little he can do to help you.

I suggest you put your server in and see what is happening now, maybe it will work. You and he will need to work together to make sure that the format, framing, etc are the same at each end. The outside vendor will probably be of little help because what I gather from this conversation is the vendor T1 is not directly connected to your server. It is connected to the PBX and then routed to you by way of a hunt group to another T1 that connects to you.

It just list board locations and names. A note at bottom states all DS1 sources result in stratum 4, type 2 synchronization.

is what he said when he did the display sync.

My server is in place currently, I can get it to see a call came in and attempt to pick up the line but on the phone calling it just keeps ringing. Its like I dont know what to tell his system that I picked up the line.

I'm guessing the maintenance commands are somehow specially installed or limited to a more admin type of a user?

I think I might have him try setting it to ISDN-PRI and using lineside. The other people here have said the line needs to be set to lineside in past installs.

Thank you for all your input, it has helped tremendously.

When you display sync, at the top of the screen are two fields titled "Primary:" and "Secondary:". This is where your T1 sync source is shown. If "Primary:" shows 1A as sync source you have issues outside your control. You are going to need someone working at the Definity to help you get your server working properly.

You change it to an ISDN-PRI/lineside T1 but I don't think that is all that must be done, it sounds like there is some system programming that must be done also. What you want to do does not require a lineside T1. And the person working on the Definity will need to know how to do ISDN signaling. You may need to hire an Avaya Business Partner to help. What you want to do is not difficult but I do not believe the person on site is familiar enough with the PBX to do it alone.

He said for the primary it has 01B08 and secondary is 01C06 and that those are a local and a long distance T-1. Those are just other interface cards in the cabinet right? Is that what you meant by 1A?

The answer he gave you is the one you want. If the PBX is not clocking off a T1, it is clocking internally and this could be a source of slips. If it is clocking internally, the primary sync source would be 1A not 01B08.

That is not the source of your problem. All you have to figure out what is different from the old server and your new server and make the necessary software changes in the PBX and your server. Simple, right?

To even begin to try to help with that, I'm going to need a lot more info. Exactly what was the old server doing, how was the PBX programmed to accomplish that, what do you want to do with the new server, what changes do you need in the PBX to do that? I do not know what questions to ask because I do not know the current configuration.

What is set up currently is a Brooktrout card that the developers on the old software said to basically set the line coding and framing(B8ZS/ESF) and all should work, if it doesnt its the providers fault and they have to fix it. With the new server it is using a Dialogic 240JCT-T1 board with our software. Typically we get it working by being provided the information of what the line is going to be sending us to seize the line, then we send a wink back or not and let the phone system know we picked up the line and things like that. Both of the servers are used for inbound dictation.

I think what we are going to try and do is move the server from where its at currently (4 floors up) and take it to the phone system in the basement then plug one of the Ts directly in and work with their provider and if that works see what can be done to try and bypass the Definity

martinyoung

If you are going to bypass the PBX entirely, I will assume that your server does not need to interact in any way with telephone calls answered by a person.

A direct connection to the outside world does limit your design options. Your connection will not be a hunt group, it will be the 24 channels directly off the T1. Now the list of questions you have become relevant. Make sure that the vendor has isolated the T1 you are connecting to so that all calls you are expecting will come down that T1 only and calls you are not interested in do not come down that pipe.

One more thing, that existing T1 will need to be deprogrammed in the PBX.
