Upgrading 0X32 from Analog to T1 with DID 2

[randy22]

In about a week I will be removing an existing switch and replacing it with a 0 X 32 (corporate standard) with R1T1 software.

Currently there exists a T1 from South West Bell with 12 bi-directional channels on it.

I realize that I will need a DTI & Service unit to accommodate the T1. The services card NTBB24 goes in slot 1
2 port fiber expansion in slot 2
DTI, NT7B74 T-1 Card in Slot 4. I will also be installing a 0 X 12 expansion cabinet which will hold my DID card in slot one.

From reading other forums I have gathered:

Disable DTI Card and program as follows.

Protocol: SL1 (check with your Telco Carrier for setting)
Type Slave
Bchanseq: Ascend or Descend (check with your Telco Carrier for setting)
CO Fail: TIA–547A
IF Levels: ISDN
Framing: ESF (usually ESF, check with your Carrier
Internal CSU: ON
DSX1 Bld: 000-100
Line Coding: B8ZS (usually B8ZS, check with the Carrier)

Is this correct?
Will I need key codes for the DTI card?
Is Release 1 T1 software current enough?
Do I create a line pool for out bound calling the same way I did prior to the T1?
Programing the DID - Where can I get instructions?
Thanks a bunch.

The software you ahave will work.
You do not need key codes for T1, just for PRI.

How to Install a T1:

You must have either a Services Cartridge (slot 1) or a 6-port Combo card (slot 2) in order to provide clocking for the T-1. Only one of these is needed, even if you have two DTI cards.
The DTI card should go into Slot 4 first. If you have a second card it would go into Slot 3.
You must disable the card first, program the card for T1. Then re-enable the card.

{Need to have either an external CSU, or turn the internal one on. If customer needs to use some channels for data then they’ll need a CSU/DSU to split off channels before the 0X32. OR to split off data channels after 0X32 they’ll need a Nortel Data Interface (NDI) plus bandwidth allocation key codes}
DSX1 Bld: 000-100
Line Coding: B8ZS (usually B8ZS, check with the Carrier)
ClockSrc: Primary (second card would be secondary)

Re-enable the card in Maintenance now.

Instead of using Analog DID and spending more money, you can have the DID numbers come in on the T1. I would make sure you have some POTS lines just in case T1 goes down (for emergencies).

Just a thought.

Good Luck!!

Thanks for your complete and timely reply. This has been my first posting on this forum and I hope to be able to help someone out as you have for me today.

THANKS AGAIN

I need some clarification on DID. Usually a Telco will assign a bank of 25 or 50 DID #'s to a company. If I have 12 two-way channels in my T1 can I assign more than 12 DID's to stations?

 

[executone]

What Telco does is pass you thae last 3 or 4 digits of the DID number. You program the digits as target lines and then assign that target line to the extension that is to recieve that DID. The same would work for your main phone number 999-525-1234. If you were using 4 digit plan then Telco would pass 1234, you assign it a target line and the assign yhat line to ring operator extension. The 12 channels on the T1 can be used for incoming/outgoing and DID lines as long as your Telco sets them up that way. You can only have 12 parties using the channels at one time, but that is still better than the 4 DID crkts on the analoge DID card.

I hope this clears it up a little better for you.

Good Luck!!

What happens with the T-1 is that the Telco basically knocks on the MICS's door and asks if anyone's home, the MICS winks back (wink signaling) and says, yes, we're here, send your digits. The Telco sends the digits over whatever channel is available. We receive those digits on target lines. The target lines are assign to an extension..... rings the phone.

If you are using R1 T1 software then the prompts will come up differently than above. I don't have this level software in my lab so I cannot be as complete as I would like but this should get it done for you.

Programming the DTI card:

A. Configuration - Show
TCs on KSU - Show
TC1 on KSU - Loop - Change this to T-1
Discon time: 460 milliseconds - Leave default
Answer timer - 2 secs - Leave default
CO fail - TIA547A - Double check with your carrier
Framing: ESF - Check you your carrier
Internal CSU: On - Leave default
CSU line bld: 0dB - Leave deault
DSX1 bld: 000-100 feet - Leave default
Line coding: B8ZS - Check with carrier.

Programming the channels:

Trunk/Line data - Show
Show line: 001
Line Type: E&M
Ans mode: auto
Ans with DISA: no
Signal: WinkStart
DNIS Number: N
Dial mode: Tone

Programming the target lines (121-248)
Show line: 121
Rec'd #: enter the digits that telco is sending you.
(A received number can be two to seven digits ling (programmed in 6. System Data). The default length for an expanded system is 3.

Then you would just assign the line to the phone.

See how that works for you. If you have trouble, let us know!

Great description melissa. All I had was 4.0 handy.

 

[randy22]

Thanks for both your explanations (executone & mroberts), they have helped clear things up. It sounds to me that I do not need the 2 port expansion unit or the DID card, as long as the Telco is sending me the digitson the two/way DID trunks.

As this is an existing T1 on a Mitel switch and I’m moving to the MICS 0X32 with DTI & Service card can I accomplish this without involving the telco?

Thanks

 

[mroberts]

Well, if what they are sending the mitel is a two-way T-1 circuit you might get away with just calling Telco and telling them of the change and that you are using channels 001-024.
All you are really going to do is to go straight from their SmartJack to the front of your DTI card.

DID cards in the MICS do not support two way DID so you would have to go T-1 circuit as opposed to two way DID trunk. MRoberts
