Spurs - I think the recomendation is in the neighborhood of 1000 meters. Of course it depends on the guage of wire.

You can find some distance recomendations in NTP: 553-3001-215
"Telephone and attendant console installation".

If you want to get techie - you can use Ohms Law, but what I usually do is take the Box/Spool of cable - install a jack on one end and connect the other to a TN in the IDF that I'm planning on running the cable from.

I've been in IDFs (that are the furthurest from the switch) and installed a jack on a Box of 1000' Cat 5 and the phone came up with no problem....

Long enough.

I think around 1000 meters is suggested but it depends a lot on the cabling plant, I have about 100 or so sets that work just fine a few miles over the river and through the woods but with high quality cable.

There is definitely specs for cable for digital sets but a quick scan didn't show me anything for analog. There have been cases of Meridian 1 systems being used for small Central Offices (some of you may remember MMCS) where you could be at a considerable distance. Typically, as long as you can still get enough ringing voltage to the analog set (and the phone itself is sensitive enough to pick it up) then the phone will ring.

If all else fails you can always use OPX :wink:

Analog can go a long ways and one palce we have a switch has them going about 10 miles but thay are using some kind of load coils like co's use.

I've used a Dynatel tester that measures the distance of the path and I believe it will give you load coil data if the path is long enough to need them.
