New T-1 Line Specifications

[LTympanick]

Dear VG,

 

I currently have on order a Dialogic D240JCT-T1 card.

 

I am trying to verify what I should communicate with my Telco regarding specs for my T-1 line.

 

In particular, I'm wondering what to tell them with regard to Basic Circuit Info, Signalling & Protocol.

 

With regard to Basic Circuit Info, should I be specifying, T1, PRI T1 or Integrated T-1? 23 or 24 lines?

 

With regard to Signalling should it be: Ground Start, Loop Start, E&M Wink, E&M Immediate, PRI (ISDN)?

 

With regard to Protocol should it be: NI1 OR NI2? Also do I have to worry about FAS & NFAS (See attachment)?

 

I just want the most conventional & reliable thing I can do to make VG for Diaglogic with Dialer work the best.

 

I have attached their order form so you can see the kinds of things they're looking for.

 

Any help would be greatly appeciated.

 

Thanks.

You should specify PRI ISDN.

 

Choose the "NI2" protocol.

 

Also do I have to worry about FAS & NFAS (See attachment)?

Select FAS (Facility Associated Signaling). The signaling "D" channel should be on the last channel of the T1 - the 24th channel. Leaving you 23 channels for voice traffic.

 

You do not want NFAS. ISDN NFAS allows a single D channel to control multiple PRI interfaces.

Thanks for your response.

 

Is there any way to get use of all 24 T-1 channels?

 

I've got a 4-wire connection vs 2-wire? Does that help?

 

It's a bummer to have to give one up?

 

I will talk to the Telco about this as well but just wondering if from your extensive experience you have any creative thoughts on this?

 

Thanks.

No. The T1 ISDN is a 23 channel service.

 

All ISDN lines are 4 wire.

[LTympanick]

Right.

 

4-Wire it is. Looks like since I'm connecting directly with an LD carrier PRI-ISDN is not an option.

 

Looks like it will be CAS Robbed-bit, E&M wink.

 

Will VG Outbound Dialer be able to work with that setup?

 

Looks like the D/240JCT-T1 supports that.

 

Should it be any problem?

 

With this signalling, I get to use all 24 lines.

[SupportTeam]

Configuration is a lot more difficult with CAS/Robbed-bit type setups.

 

There are no problems once it is all configured properly.

[LTympanick]

OK,

 

Now sounds like they can give me PRI-ISDN.

 

I will go with it if I can.

 

Is there a setup in the standard VG delivery that properly configures a D240JCT-T1 for the PRI-ISDN 23 channel option.

 

Also, do I pay for 23 or 24 lines in this case?

 

Thanks.

Yes. Have a look at the sample Config.xml files provided.

You'll need to get the 24 line license, there is no 23 line license option.
