I have 2 locations.
The first location has a DXP in place.
I have purchased a DXP for the second location. I have fiber optic lines connecting the 2 locations.
I have 2 RAD FOM-T1 modems to convert the fiber to copper T1.

Now, what options are there for connecting the two systems via T1 having the intercoms work together? (100 series numbers system 1, 200 series number system 2)

I have read the system-to-system networking docs, but are there other T1 options that don't require the DXNET card. They seem quite expensive. I am working for a Christian camp that can't afford to pay the $3000 each that king is asking for them.

You will not get true networking, but you can always set up for E&M tie lines.

Could someone give me a quick run down on E&M tie lines.

which cards are required?

what features I can expect to work between systems.

which documentation to persue.

Thanks in advance for the help.

UPDATE:
I think I found the answer to my question.
(copied from multipurpose line card docs)
NOTE: Intercom feature codes of one DXP are not available to callers from the other DXP nor can those callers
access a line through the distant DXP using line group access codes.

I am assuming this means I have to go the DXNET direction.

Anyone have a pair cheap?

I'll check my stock tomorrow. I had at least 3 new ones for service spares last time I checked.

A less expensive alternative would be to use standard T1 boards in each switch. If you are not looking to get centralized voicemail and you could get by with dialing say 8 plus the other switches ext. numbers then this would work out less expensively than networking with DX NET boards. Email if you are interested in price for the T! boards as I have them in stock.

Sundance will have the T1 cards too.

Go with the T1 option if you do anything at all. Is this a campus environment or due you need to get a point to point form the C.O. The monthly charge could be your real cost and not the one time charge of the DXNET cards. What version software do you have in the DXP. First neworking was 12N and was a seperate software. Networking is in all software 15 and higher.

Everything is local. We have a large camp with the 2 locations a little less than a mile. They are connected with a 12 pair multimode fiber. I found out today that the DXP I just purchased has a DXP-T1 and the sync card. Until can get a second T1 card I am going to mux 4 fxo lines on a T1 using an ADC Opera that I have on hand and try to come into the second DXP via the T1 card that I do have. I just hung the second DXP on the wall. I am not looking forward to setting up the ADC and the T1 settings on the DXP. This is pretty new stuff for me.

How much could I expect to pay for a T1 card on the second hand market? I only paid $400 for the DXP that I just bought. It came with 3 DST, 1 IST, and 1 T1 card, modem, ring generator, service card, and cpu.

If I were to connect the 2 systems together via the DXP-T1, would they have to be PRI cards? Is this a difficult setup for an amature? Do the systems have to have the same software release. I have one R.10-C and one R. 13-B

One more question, what is the cost of a software upgrade to 15-C from my current revisions?

15C is a very good release if you can find it. the DXP plus is easy to upgrade but you need to find the E-proms for a DXP. You do not need to have PRI to tie the two together.
If you do have PRI cards they can be converted to DXNET with one chip change, I did that at Comdial all the time. The price for any phone equipment varies alot. Yes I have gotten whole switches for almost nothing, but if you need a card you should buy it from Sundance because you will have a part that is tested and they will stand by it and you will get support from this board.

System Update....

I have the 2nd dxp mounted and the cards installed.

Found out that I needed db15-rj45 adapters for my RAD FOM-T1, they should be in today.

I have a small snag that I hope to find help with. I have VMMI for 10c, but my new system has 13b. Is there anyone that would be willing to email me a copy. I have tried working with the VDT, but it isn't much fun.

I am going to try to get the ADC Opera setup this afternoon to mux my 4 fxo lines onto the T1.

QUESTION...
Since I am using an Opera to mux my 4 fxo lines (from DXIST card) onto the t1, would be easier to demux the lines using another Opera and bring 4 fxs lines into a loop start card rather than try to bring the t1 directly into the DXP?
(Reminder...At this point I only have one DXPT1 card)
