Maximum Distance Cabling for a Partner Extension

I have a customer on a 500 acre church camp. The camp office needs phone service to lodges, the kitchen, the pool, the maintenance building from the office. They want the exension to have dial 9 for call restriction, but allow them to use the phone sets as internal intercom to each location. One of the lodges is located 1 mile from the office. A straight digital phone system such as Nortel CICS and MICS does not have enough power to maintain the extensions without static. It came to me the Partner is a hydrid phone system that uses analog phone sets. I thought since analog has a higher power generated it could handle the distance of the extension. I was looking a Partner II or Plus due to the church camp of course is very frugal.
 
The maximum distance with system phones is 1000'. For standard devices (tip/ring) you're looking at about 3000'.

How about going with an Engenius commercial-grade cordless phones?

If it ain't broke, I haven't fixed it yet.
 
I have not heard of that product. The customer has tried several two way radios designed to go 30 miles and the models they have tried don't work. Cell service is spotty at best. No data cable such as Comcast available more than 75' off the road side. The other thought was to just go with something like AT&T Multiline analog phone sets.
 
Here is the telecom page for Engenius:


Running copper outside of buildings will require, among other things, proper bonding and grounding of the cable at the point of entrance at each end. Then there are the costs associated with proper installation of a cable that need to be considered.

If it ain't broke, I haven't fixed it yet.
 
EnGenius sounds expensive. The diggest problem is that this 500 acres is in the hills of TN deep valleys surrounded by limestone mountains.

There is phone cable pulled to each extension site, but no one knows the path of those cables and exactly how long they are.

Let me just ask one more crazy question is the Merlin Legend a hybrid system like the partner? That handles standard phone sets.
 
Yes. The Merlin Legend (and Merlin Magix) will support Partner telephones (also known as ETRs). The Legend and Magix will support OPT cards that will give you a long reach when you connect standard telephones.

The existing cable can be tested, but it is crucial to make sure that cable is properly bonded & grounded.

If it ain't broke, I haven't fixed it yet.
 
I need to clarify 1 point I made above. The Legend and Magix are really digital systems, but can support the hybrid phones.

The MLX series are the digital phones introduced with the Legend and the 4400 series were introduced with the Magix.

If it ain't broke, I haven't fixed it yet.
 
If you use a Partner system and place SLT's ( single line telephones) and use loop extenders you can reach out to about 25K feet, only thing will be no voice page, all calls will ring to SLT's
 
Thanks allisland! That sounds like it is definitely on the list.
