merlin legend TTR's

[31LDog]

I have a question about TTR's and testing. I have a Merlin Legend with the following Config:

Hybrid/PBX

Slot 0: CKE3 CPU (R7, V10)
Slot 1: 408
Slot 2: 408
Slot 3: 400 GS/LS TTR
Slot 4: 012
Slot 5: 012
Slot 6: 012
Slot 7: 012
Slot 8: 012
Slot 9: 012
Slot 10: 012
Slot 11: 012

Several callers are experiencing problems dialing out. I have checked all restrictions, ARS, FRL, allow and disallow list and don't have anything that would prevent placing calls. When trying to dial out with my testset plugged directly into an 012 module I may get out 1 of 10 attempts. Sometimes when pressing 9 to access the 70 pool the tone isn't even recognized and you have to hang up and try again. I tested TTR's by dialing *04 the TTR # then 123456789*0# but don't get any confirmation tones (on any TTR). When dialing 03 for the 3rd TTR and 13 for the 13th the 3 is not recognized and I don't get dial tone to continue with the other string of #'s. It does the same thing with 06 and 16. I performed the same test at another site to make sure I was doing it correctly and received 3 confirmation tones after testing each TTR. Any help, suggestion, or input is appreciated.

It's difficult to believe you don't have enough TTR's with all the 012's you have. I assume you have done a cold restart, at some point, checked the phone used for the TTR test. You might look at the maintenance logs to see if there are any entries showing problems as well. Also remember that if there are dead lines in pool 70, there will be dead air unless you pull it out of the pool, or fix it with a good line. You may do well also to verify that any ground start trunks are set in programming as ground start. If you have a GS line, and set it as LS, it will answer, but won't be available for outbound calls. You may, of course had a bad 012 board, and if so, would get dissimilar results from board to board. Are the callers that complain using the same 012 board? Several possibilities.

Most of the callers with trouble dialing out are in the first carrier but not on the same card. The caller having the most trouble is on the 2nd 408 module. This caller actually has a private line which is only assigned to that extension. When dialing out on that private line before the system I didn't experience any problems. We did have a line in the 70 pool that was dead but the problem was corrected. I did do a restart but not since repairing that line. I agree that we should have plenty of TTR's but was confused by the results I got when testing. I tested TTR's from two different ports on an 012 module but got the same results. I'll try another restart and check the maint. logs, and GS lines. Thanks for the help.

Multiple carriers, are you restarting the #2 cabinet first, then the #1 cabinet?

unfortunately, bad TTR's are hard to isolate. They can work some of the time and not others. Is everyone having problems or is it isolated to a group of people.

 

[31LDog]

Yes, I do know how to do a proper restart. Several people have complained but I have only tested from (2) different extensions (1 on each 012 module in the first carrier). It seems that most of the complaints were from extensions in the first carrier.

Are any of the people on the 012 boards experiencing trouble or are they all on the 408 boards. You indicated that the most significant problem was a person on the 2nd 408. Just seeing if it really is a potential TTR trouble or maybe just a ATL board or phone trouble. If it is a TTR problem, you can alsp try rolling some of the 012 packs to move the TTR's around in the switch. Make sure you do a board renumber. For instance, swap the 012 in slot 7 with the one in slot 11. This won't resolve the problem but may move the troubled TTR resource to a place in the switch that is rarely accessed.

 

[Ghostin]

the TTR's are supposed to be accessed in a circular manner. but Gokings has a point about the problem being with one of the cards. Are you using DID service? Voice mail? If so, are you expierencing any problems with those? If you had bad TTR's, they would affect everything needing a TTR.

 

[GoKings]

Ghostin...can you advise me where you found that info about TTR's. The notes that I have indicate that TTR's are linear and start by using the last TTR in the switch. This is only a hand-written note that I have based on working with a Tier3 Engineer in the past, so it may not be accurate.

I have not had a chance to get back to this site to check on things you advised. Lightning has kept me busy replacing modules at a lot of their other sites. As a matter of fact when first being called out to this site I had to replace a panamax module that was damaged by lightning. They don't have any VM, CAS, or DID's. It's a pretty basic setup. I did have trouble dialing out from two 012 mods. so the problem is not just isolated to the 408. The 400 GS/LS TTR module in the first carrier is not even being used. I don't know if it was used at one time or if someone added for the TTR's (do they need it?) I will try and get by there today and check things out. I'll update you on what I find.
Thanks again
