NORSTAR 6.0 T-1/PRI QUESTION 1

[BagsNYC]

Now that the 6.0v software is capable of a third T-1 card, can it be utilized as PRI? Also, is there a need for timing for the third card? I was always told there needs to be either a Combo Card or Services Card for each T-1 in a switch..Please advise.Thanks

 

[commsguy]

Yes it can be used as PRI. I believe (don't take my word) the timing is built into the new trunk MOD.

Thanks Commsguy.
What do you know about this "new trunk mod"? Does it only work with 6.0 and above? Any other details would be helpful..Thanks

 

[salo0920]

Are you suggesting that the old trunk module cannot handle the DTI card?

I was of the impression that the timingwas derived from the switch itself (which gets it from the line usually.

 

[BagsNYC]

Actually, salo0920, the information I have since learned is that the DTI card that goes in the trunk mod is a different type of card. The DTI card should be installed in the first slot of a trunk module that is installed in the mod 8 or 7 port of the first 6 port expansion card in slot 2.

 

[commsguy]

Since i have never used the third DTI I was not sure. salo is right, the new DTI card is what is different. NT7B74AAAA is the new part number.

The card must go into slot 1 of the Fiber trunk MOD.

OOOPS sorry.

In my defense i did say don't take my word.

Nothing to be sorry for,Commsguy. I am learning as I go and am here for help like most of the rest of us on this site. I appreciate your response as always...

My understanding about the third T-1 is that it can be used for PRI but you need the mcdn key code. It's for networking purposes or something like that. But if you are going simple t-1 all you need is the new version card. You should already have a service card or combo card in the system.

 

[BagsNYC]

Phonedoctor,

From what I understand the timing for the third T-1 card is built into that new type of card. I hadn't heard about the different keycode though....

 

[phonedoctor]

BagsNYC,

All I can tell you is what I was told in a Nortel training class "There's a right way, a wrong way and then there's The Nortel Way!" I am in the middle of trying to get one to work as well and having all kinds of issues. And I HATE issues....

 

[BagsNYC]

Phonedoctor,

Did you say you are in the middle of installing a system with third PRI/T-1??

I would love to hear details on how you made out. You already mentioned you were having issues,so I'd definetly like to hear how you made out..

-Thanks

 

[salo0920]

I would too. I am about to try the 3rd T1 scenario in a standart fiber trunk using an NT7B74 (the old DTI) Wish me luck!

 

[mroberts]

Here's the deal....

On the MICS with 6.0 swoftware you may add a third T-1 circuit to the first slot of the first or second trunk module on the system. The DTI card that fits into the slot is a different card. The part number is NT7B74AAAA. The older card WILL NOT work in the trunk module. There is NOT a new trunk module! Simply a new card that goes into the first slot of trunk mod 8 or 7. Nothing else can then be used in that trunk module.

Clocking/ timing is still controlled by either a Services card or 6 port Combo card as usual. Since you have so many T-1s in the system it would be wise to either add a second 6 port combo card (if you have XC sw) or a Services card so that you have sufficient DTMF receivers to handle three T-1s.

The MCDN (Meridian Customer Defined Network) is for when the customer is networking two systems together using a point to point PRI circuit. This enables the customer to add a NAM 4.1 and have centralized auto attendant/ voicemail.

You may add a third T-1 with just the new card and the appropriate services or 6 port combo card. OR add the PRI enabler code to make it a PRI. OR add the MCDN keycode to network two systems together.

I have this up and working on my switch here in my lab.

As usual, mroberts, you are right. The older NT7B74GA is not even recognized when put in the trunk module(8). What is different about the newer card??
