Our resort telephone system has recently been replaced by one made during this century.
Prior to this, our maintenance facility (some 5000 ft from a demark) had its own separate PBX - fed by analog lines from the utility. The new system has digital extension ports available that can be routed to the maintenance building - but the distance involved seems to be a problem... connections cut off after about 15 seconds. We would very much like this location to be incorporated into the overall system.
Does anyone know of an affordable bi-directional digital line driver device (or circuit that can be built) to solve this problem? The ones offered by our communications contractor are prohibitively expensive (inescapable budget constraints). I can offer a modest bounty for a workable solution.

What brand is the PBX Emax? In a previous life I used to install and maintain these things for a living. Just a note - Toshiba's maximum distance for a digital station is 1000 feet. There are a few ideas you could toy with though... One is you can try is to double up on the pairs feeding the sets (if there are pairs available.) Another option is to install IP phones that are specific to your model of PBX - this is what we did as there was no copper between our building and the base. You could also use analog stations in the maintenance building. As for a digital line driver - I've never even come across one. Did they happen to give you a name or model number of the one they quoted you? I'd like to see them!
Edit... Ok I lied - I have seen digital line drivers, but when I was in the field they were called OPX adapters (Off Premises eXtension) and they were the predecessor to VOIP technology.

Maybe see if what's needed for the contractor's solution is available on ebay. I've saved my company a boat load of money that way. Also took the actual phones off the service contract, it's a lot cheaper to replace broken ones with ebay pruchases. With so many companies going out of business I imagine there should be a pretty good supply these days.

Call off the SWAT team - problem solved.
The system installer tied the extension in question to terminals which were also tied back to the CO. I have no idea why he did that.
With the parasite pair removed, the digital extension works just fine at the 5500ft distance.
Thank you for all the help offered.
