T1 module - Appropriations by the LEC 1

[pilasz]

I have a client who needs substantial amount of lines - whatever the cost. Since he has already Partner v6.0 installed, the best course of action would be to add the T1 module. Now with the question:
What appropriations need to be done by the LEC on the new T1 to make it happen? Or, what we need to request from them to make it as smooth as possible?
I will be dealing with verizon.
I tried to do an research (a lot) but coudn't find any written info. Actually this forum was the best resorce so far...

Are you running voice and data over the same T1? Depending on that, you may need a csu. If you run dual, use a 3160. As far as the programming, i dont recall any special programming they need to do. They just need to tel you the usual.

T1 card in slot 1. framing type, encoding, signal type and line build is the info yuo need from the lec.

No data, just voice, and it will be ordered as a new service. That's why I need to know what we need to request from Verizon. Like signaling, type, etc.

No, you need to tell the provider what you want, or you won't be happy with the results.

The T-1 has to be channelized, not a PRI. The module accepts only channels 9-24 for voice operation, so it is economically intelligent to split off channels 1-8 for data. To do so, you'd need a drop/insert MUX in an external CSU. If not, the module has a built-in CSU. If you are going to use DID service, you need to specify the number of digits you want to receive (max 4) & wink start. For non-DID, the provider may have a preferred seizure type, but wink or ground start is best. For framing, ESF & B8ZS is preferred.

Be aware there have been reports of instability in the Partner T-1 module in the way of spontaneous system restarts. There is also some concern regarding heat from the T-1 module, be sure adequate ventilation is on hand. The T-1 module is required to go in slot 1 of the carrier, so some re-engineering of the system and lines may be required.

The client has already T1 for data conectivity, so the additional data channels are not an issue. Foremost concern is the stability of the system (I have seen the report about restarts). Since they are the customer service, they will welcome few minutes without a calls, but long outages are out of the question. I will not be using the DID service. My only concern is to specyfy correctly all the requirements, so the LEC has no choice but provide me with the right circuit.
And guys, I really appreciate all the help I'm getting...

Well then, you need to tell them "16 combination (inbound/outbound) voice channels on a channelized T-1, utilizing channels 9-24 with ESF, B8ZS framing and wink start."

At that point, you can use pretty much all the defaults built into the T-1 module and you'll only have to tell it which channels are live. Almost plug and play.

Verizon is actually pretty good about special circuits, as far as service and reliability goes. You are, however, at the mercy of the facilities they put your span on, which varies greatly from town to town and sometimes from street to street.

I wouldn't be too concerned about the restarts, it seems to be a minimal problem affecting a few units. Cooling is a big key, and down time on a restart should be less than 45 seconds, even if it brings the span down on the reset.

Oh, and you can specify or they may require you to have, touch-tone or rotary signalling. Most carriers prefer rotary.

And if they don't supply dialtone (or charge extra for it like AT&T does), the Partner T-1 module can supply it.

Thank's a lot. And, beleive me, I know what you mean by "being at the mercy". I just finished the site (4 story buliding, bank, loan office, insurance etc.) The service was delayed for 5 weeks. The company moved into the building and had no service (well 3 dial lines) for almost three weeks. No data or voice. And the Verizon's D-slam and all associated equipment was right in the buliding!!!
Well, thanks one more time. Hope all goes well...
