Sounds like he will have to do with less phones or put in a system....unfortunately, I think he'll just do less phones.

The distance affects the features like hold, intercom, page. For a building the size you're describing they need a system, but all you can do is inform them and go from there. I've seen a couple of these systems that are exceeding the 600ft manufactures limit. So what the drop dead distance is will be anyone's guess.

I don't know this system at all. However, if I was you, I'd do the following:

a) have all cables & X-Connects ready B/4 you get the phones
b) make sure client keeps the sales receipts for those phones and can return them when they find that they don't work
c) have the name & number of a reputable system's dealer on speed dial.

Dave, I'm way ahead of the dealer, I routinely used an outfit from Columbus to take care of my Vodavi system when things are needed.

Hal, I don't quite understand the LOOP concept you're speaking of. Can you point me in the right direction...perhaps a photo?

Between past installations I've dealt with and a pretty complicated setup for an inmate telephone system I routinely deal with, I can examine quite a bit of finished work closely...just knowing what these LOOPs are puzzles me!

Loop from the incoming line one (for example) to the first pair of each station cable.

Line 2 goes to the 2nd pair of each cable, etc.

Each cable at the end would have all 4 lines available, split out as you wish/need.

OR Loop the incoming line down the left side of the block opposite the 1st pair (again for example) of each station cable & use bridging clips to connect to the station cable.

Same for each line.

Basically you are not cutting the cross connect wire. You are continuing it on to the next set of terminals.

Similar to the loops on this block...but obviously to the appropriate pairs?

That site doesn't allow direct linking of images...but I looked on there and yes, you would just loop each pair for each line.

will the cable co. equipment even be able to drive the ringers in 16 phones. Most telco lines would have a problem with that depending on the REN of each phone

(You can always just add a space to the end of the image URL to view it w/o going through the site...it strips the HTTP_REFERRER header)

The REN is supposedly 0.15-0.25 per phone according to manufacturer. Cable company said they guaranteed a REN of 5....it only took me 5 different people to find someone who knew what REN was.
