Hi Guys,

Does anybody here who has a complete listings of the limitations of the Definity Prologix (G3csi)?

I have encountered a severe and strange problem about inserting a TN2793B Analog Circuit pack on Cabinet C.

Problem description:

1. A week ago, I tried inserting 2 TN793CP on cabinet 1C01 and 1C02... After 10 mins or so, the boards raises a major alarm (red LED lits) and when i tried to test the boards, it is stating that it doesn't have any dialtone. All maintenance command was used(so therefore the activity was rescheduled) A few days after the client wants me to dialup to their system and add a few CO trunk member, however all license where already used-up so it wont allow me to add more ports. In Short the client Purchased additional license for trunks and ports, then I loaded the additional licenses after a few days more.

2. Yesterday, I brought a TN2793 v4 and a TN2793B v18 and inserted the 2 cards on 1C01 and 1C02, after 15mins the same alarm occured. When i tried to display the alarm, it is stating that the problem source is "on board" and no dialtones where provided. All maintenance commands where used. busyout/reset/release

To test the 1C01 and 1C02 slot, i tried getting an existing TN2793B v7 on 1A05 slot. I busyout the board, remove the amphenol cable terminated on 1C01 and insert the card on 1C01, after a few minutes the same alarm occured and the LED lits red.

Now here is the catch, for a backup plan, I inserted 3 old 16 port analog card on 1C01, 1C02 and 1A05, and it works perfectly!

3. I went back to the office, and tried inserting the 2 cards (TN2793 v4 and a TN2793B v18 ) that i brought from the client to our PABX. Same error occured, and im perfectly sure that the cards i brought were already broken.

Observation:

Its like the PABX is destroying any additional 24 port analog card inserted to it, however the weird part is, i tried pulling out an existing 24 port TN2793B on 1A05 which is existing and perfectly working and when inserted on 1C01, After 10 mins LED lits up, when you disply the alarm it says the the problem is on board.

Software load: R11

The Prologix has the same limitations that the G3si and G3i have. The same cards will work in all three systems. Sounds like you might have a problem with those slots in cabinet C.

You state that all maintenance commands were used and then list busyout, reset, and release. Did you try test? When you go to the error log, what do you find?

Thanks for the reply.

Yes I did, after I insert the 24 port analog card, I did some test. Just right after inserting the card and do busyout, reset and release, then test. When the test starts, the red LED shows up and reflects a major alarm on the board. I'm getting a no dialtone alarm. When i try to enter the list con all, the boards are seen and when i enter change/disply circuit-pack no conflicts where seen.

The weird part is, when I returned the 16 port analog board on cabinet 1A05, 1C01, 1C02 it works perfectly and im getting dialtones on all ports.

Do you think I need to have a call classifier on cabinet C?

Thanks.

martinyoung

No, you do not need a Call Classifier in cabinet C. You only need one per port network and a Prologix is only one port network.

You said you tested the slots with a known good TN2793 and it also alarmed. When you returned it to the slot it came from, was it ok? I am still inclined to believe you have a physical problem with cabinet C itself. Perhaps bent pins that don't become live until a 24 port card is inserted. Take a flashlight and look at the back plane for the slots in question.

Also, the new boards that alarmed, did you try them in a slot that already has a TN2793 in it?

Yup, when i tried getting the existing 1A05 card (which is 24 port analog) then put it on 1C01 it did alarm after a few miniutes. And when i put it back on the original slot which is 1A05, the alarm is still there.

Also, the new boards that alarmed, did you try them in a slot that already has a TN2793 in it? ---- Yes I did. Still the same.

If you can observe, almost all cabinets A and B, already filled up with a 24 port analog, and the remaining cabinet C only hav 16 port. I have asked our pre-sales to reconfigure the clients PBX and the results on the avaya configurator requires a call classfier on cabinet C, in which the current setup doesn't have.

Ok i'll be checking the bents pins.

Ok i'll be checking the bents pins. However if there is a bent pin, the 16 port analog wont be latched and wont provide dialtone. I already encountered problems with those pins before, any bent pins on the backplane wont allow any equipment to be inserted. If you push it hard, the pins will be broken.

I have been able to latch cards into slots with bent pins with no problem. If the pins are bent over far enough, latching the card will finish bending them flat or fold them up. I have also had the pins bent over just far enough that two pins would enter the same hole on the cards. The normal pins will not prevent you from latching cards if they are bent, only the guide pins are strong enough to do that. Trying to straighten them will break them off.

Another Call Classifier is not going to help with the cards failing. A lack of tone ports will not alarm another card. I definitely suspect those two slots of having a physical problem. Examine the pins very closely.

I'm currently here at the site and did some physical observation on the backplane pins. I have removed the circuit cards on 1C01, 1C02, 1C03 and compare all pins. No bent pins are seen on 1C01 and 1C02, i compare all pins on 1C03 and its all the same. I did ask somebody to double check if there is a bent pin on the backplane. Still no pins are bent.

Thanks.
