Can a network guy move a phone system to another T-1 line?

We are switching our phone provider from Integra to C-Beyond.

I don't have much experience with phone systems, as I'm I network guy. I guess I'd like to attempt to handle this change if I can rather than paying our local phone provider $200/hr for after hours rates.

Here is a picture of the equipment in the phone closet: <A Href="http://www.oneadamclaude.com/PhoneSystemPic.jpg">http://www.oneadamclaude.com/PhoneSystemPic.jpg</A>

There is a cable that comes out of the Adtran (highlighed in Cyan) that is a 25 pair connector that plugs into the 66 block. All of our phone numbers are marked in pen on this 66 block.

What is the name of this 25 pair cable (it looks like an old school SCSI cable)?

When C-Beyond installs their equipment, how does it interface with the existing phone system? Will they provide another 66 block that I will move the existing wires (Red) into the new 66 block? Or, will it have another 25 Pair cable that I just unplug from Integra's Adtran and plug it into C-Beyond's equipment?

Also, and unrelated question: The blue arrow points to a jack. Is that the demarc? When the phone guys talk about "extending the demarc" does that just mean running the blue cable to this jack in the customer's office?

Is there anything else I should know to complete this task?

Thanks in advance!

your new t1 provider should come on site to install a new t-1 interface, this unit like your current should have a female "amphenol-type" connector on it, this connector is what interfaces with your phone system.

the amphenol cable is that 25 pair cable that looks like the old school SCSI cable

in theory the current cable that connects to your adtran and terminates on the 25pair 66 block should connect right in to the new interface.  

The only problem is telephone numbers, I am unsure how many lines you have but the proper lines may not be connected to the right ports on your phone system since they may not come over the same pair. see the adtran unit you have converts the T1 back to POTS or "plain old telephone service".  Each line on your telephone system gets 2 copper wires from this block and this make up 1 line.  

your new T1 provider should provide or tag which pairs are which telephone number,  then you just wire each line port on your telephone system acordingly  I believe these connection are outlined in green.

you should probably have an install manual for your telephone system handy so you have a wiring diagram, however the wires outlined in red would be your incoming lines.  just wire your new incoming lines to them.

A Demark is where the telephone company connects your service to. You may also run into the term NID which is an acronym for network interface device, which is where the phone company's wires and your wires meet

extending your demark doesn't seem needed in this case, since you already have service in this closet, you may have to run a new wire to the nid wherever that is located, if you use the same wire your current t1 you will lose service until the new connections are made.

If you are planing to put up the new t1 along side your old, you will need to run a wire, but i think the telephone company should provide this.  

I Hope this helps, it's difficult to explain, but relatively simple to accomplish!  Please repost if you need more info or would like me to expand on something.
