Point to point T1 - can YOU see why it wont work? 1

[phonesaz]

I had to reconfigure a point to point T1 - lost original programming and documentation, long story. Short story - it doesn't work and I can't see why. I am pursuing clocking at the moment, but thought I would throw it out there to those who are smarter than I am. I am 99% sure it is not the circuit, because when I had AdTran Netvanta 3200's on it the data worked. I have removed the routers and put all the trunks in the phone system for now, just to help in isolating programming problems.

To further isolate problems, I put a pool button on an MLX phone at each end. At the main location, when I select the pool button I get intercom dial tone, but it busies out immediately after dialing a three digit extension. At the remote end, I have a fast busy the instant the pool button is pressed, and the display gives no indication of any type of outbound facility being selected.

I have attached PRI, general trunk, and UDP routing for each switch:

This is for the main location -

I have looked at this for so long I am cross eyed and could be missing the forest for the trees. I can't get any kind of an error report because the quantity of "missing or inop Dchannel" at one end (remote) and "PRI Svc Audit timeout" at the other (main) is so large that is all I get on the report.

I have cleared all alarms, rebooted the systems, busied, reset, and released the boards, had the LEC check the circuit for errors, and done everything else I can thing of. It seems like it has to be a programming problem somewhere. Thanks in advance for all suggestions!

 

[SYQUEST]

Any alarms? Is that the config before or after removing the Adtran router? How is the Adtran configured, DS1 level and channel level?

....JIM....

 

[phonesaz]

Routers are disconnected at this point, so not really part of the equation. The last 100 alarms on the main side are 'PRI service audit timeout' (code 7001). On the remote side, they are PRI D-Channel imoperative. Since both these alarms occur non-stop, there is really nothing of value on the error log since it just says the same thing 100 times.

Have you just recently programed the systems for Magix PBX? I found a couple of times when I change the switch type to Magix PBX that the trunks busied out for some reason. You can check this by going to monitor and typing in show mbusy, or you could just go to each trunk in Maintenance and see if they are Maintenance busy.

I don't recall both Merlin-PBX and Network having ascending trunks. Also I thought that one of the types would always use group 80 and the other would always use group 81. I suppose that I will need to check some of my old winspm prints to straighten out my head.

Here is a snippet of a site I have documented.

A Slot 7 Switch: MERLIN-PBX
A BchnlGrp #: Slot: TestTelNum: NtwkServ: Incoming Routing:
A 80 7 ElecTandNtwk Route Directly to UDP

A Channel ID: 1 2 3 4 5 6 7 8 9 10
A 11 12 13 14 15 16 17 18 19 20
A 21 22 23



Other side:

A Slot 7 Switch: MERLIN-Ntwk
A BchnlGrp #: Slot: TestTelNum: NtwkServ: Incoming Routing:
A 80 7 ElecTandNtwk Route Directly to UDP

A Channel ID: 23 22 21 20 19 18 17 16 15 14
A 13 12 11 10 9 8 7 6 5 4
A 3 2 1



So the programming is automatic where one type plays central office and has ascending bchannels and the other type has descending channels. Since the provisioning is automatic when selected it would appear that your Merlin-Network side is the culprit.

And I suppose my memory of the bchannel number was incorrect.

I also think the Network side is the problem - will try changing the order to descending and see what happens...

Also - I have checked the T1 slot for mb but not the individual trunks - will do that as well. Thanks

The provisioning is performed automatically when you select Merlin-PBX or Merlin-Network. That includes the wether the channels are set for ascending or descending. So unless you adjusted the provisioning afer the fact, I would simply set it to -PBX then back to -Network and let it configure itself.

 

[phonesaz]

I have no mb conditions; I deleted and then reentered all the trunks and the order wouldn't change. Great tip on the PBX to Network and back again - it did in fact create an ascending/descending relationship.

So here is where I am now at - I call a DID number that is assigned to the remote end. As the incoming caller, I have dead air for about 10 seconds and then a fast busy. The syst admin at the main loc was looking at T1 board for me and she says it goes orange for a while when I call and then drops after several seconds. She also gets the dead air for several seconds and a fast busy when she tries to dial a 3-digit extension that should be at the other end.

Based on thee scenarios, I am cautiously working under the assumption that the problem lines at the Network side of the equation.

Do you think I could have a bad T1 board or cable or something at the other end? I hate to look to hardware because 99% of the time that is not the issue but maybe the processor or T1 board is suspect?

It sounds like there is a number resolution problem if there is a delay before the busy. Looks like it is accessing a DS1 channel and, at least, trying to set up the call. I would go back through the UDP/Non-Local on both sides.

 

[SYQUEST]

The 7001 audit alarm code indicates the D channels are not communicating between the two locations.

What does maintenance show? Diagnostic test status?
Have you tried busying out and restoring both 100DS1 modules?
Power cycling both switches?
What indicators are lit on the NIUs @ both locations?
Do the DS1 parameters match Telco's? (That is why I asked for the Adtran DS1 parameters on the facility side)

Until the DCH can communicate, it won't work!

Thanks for the star.

Jim has great advise on what steps to take next. I would add that if the cards are 100DCD then what are the internal csus on or off?

 

[phonesaz]

Jim - when you say DS1 parameters, I assume you mean B8ZS/ESF? I am assuming since they are networked and the switch type is Merlin PBX/Merlin Network, that 5ESS/DMS100 etc don't play?

I checked the UDP on both sides and it is correct. The channels are ascending/descending correctly, and only the first 23 channels are on either side. I have cleared all the errors and reset the boards.

I went into monitor - and let me add all I know about monitor is to hit the ? and figure out a way to trace - it 'thinks' close enough to terranova that I can usually get something to print . Anyway - I did a trace on the b-channel group and initiated a call, and this is what I is on the link below (I think if you click full screen you will be able to read it.) Does this make any sense? I then went into the remote switch, did the same trace, and had someone go off hook both to try and dial across the pipe and to do the trunk test sequence (just to see if I could see him hitting a trunk with the monitor.) Nothing registered at that end, so it sounds to me like it isn't even hitting the T1. Again I am starting to wonder if there is a hardware failure - either the T1 board or the processor. I doubt if it is the circuit (unfortunately for me) since it was passing data before I disconnected the routers with no problem.

 

[phonesaz]

The link works, but you have to click full screen and then zoom (it is saved as a picture so I can't cut and paste it.)
Any suggestions appreciated as usual. Diana

I have spent all day on the phone arguing that this can't be the programming and (once again) the problem has been isolated to the LEC. There is a loop in the circuit somewhere that exists even when the Magix is disconnected. So... thanks to everyone for input; at least I am learning a ton about point to point T1's. I had a problem w/ another one this AM and was able to find and fix the problem easily.

So I am tabling this one until Integra says it is good. I do, however, have 1 remaining question - regarding clocking.

I have read all the documentation and am still unsure as to who controls what with regard to clocking on a point to point. In this case, the main location has a PRI T1 in slot one, which is set as primary clocking for the Magix. Slot 8, which is the point to point, shows no clocking when you look at the port. If you look under lines and trunks, it is set to local.

The remote location clocking is set to board 1 as loop. Board 1 is the point to point T1. So does this mean the remote location looks to the first location and pulls its clocking from the PRI T1? If that is true, should board 8, or the main location end of the point to point, say something other than "none" for clocking when you look at the board in maintenance? So confusing....

 

[SYQUEST]

Diana, you never answered the questions...

Yes, the remote clocks from the main via the PRI. So, if no one changed any settings from when it worked, it should be correct. Some of the questions I asked have to do with the hardware, so did you test it? You need to slow down and go step by step to isolate it. Just removing the Adtran does not guarantee that things will work, because there could be a different configuration or parameters on the point-to-point DS1 versus what is configured on the DS1 port of the Adtran going to the Magix, or even translated channels.

....JIM....

 

[CarGoSki]

Not exactly sure which but clocking is provided by one of the two merlin T-1 cards. If I were to guess I would say it is the side set to PBX.

I always try to put it into perspective by reviewing the relationship between FXS and FXO to define the duties of CO and CPE.

http://www.3cx.com/PBX/FXS-FXO.html

In IP Office it is the side set to CO. You can see the internal clock working from the sysmonitor traces.

 

[phonesaz]

I tested the boards, verified I match the CO settings (ESF B8ZS and signalling) and as mentioned above Qwest found a problem. I am going out in the morning to loop up NIU to NIU and then work backwards towards the equipment. Both boards are old school DS1 so they have no internal CSU. I don't know what else to check..clocking still confuses me but there are a finite number of options so I can try them all.

 

[merlinman]

Insure that the DS1 Boards haven't busied themselves out, I have seen that happen for no reason (other than changing some things around).

Clocking is no big mystery, it can take a little thinking if one site has 2 T1 modules however.

OK - what now? I am on site. Integra is supposed to be testing. Now instead of PRI SVC AUDIT timeout errors I am getting loss of D channel errors and the board is lighting red then going off then lighting red again. I have lost the dial tone I was hearing before on the pool button, even though I have done nothing.

So my speculation is that since I get fast busy when I go off hook, and can't make the light go orange (which it was doing two days ago when I worked on it) that the problem is either on the network or cable side again? BTW - I tested the board and it tests fine.
