maxium wire run

[jp61616]

We have buildings that are connected from the pbx to wire blocks and lightning arrestors in each basement. Now they want to hook up a new building about 400 feet away. To run 2008 and 2616 nortel phones, is this too far away for just regular twisted pairs? Our tech mentioned we might need a booster of some sort. Is the true?

I don't have the specs at hand, but I wouldn't worry about 400 ft.

400 ft is easy. no issues whatsoever

For a typical system with 22, 24, or 26 AWG standard twisted-pair cable, the requirements translate to the following allowable loops lengths:

• up to 3000 ft of 22 or 24 AWG cable
• up to 2100 ft of 26 AWG cable

Here is the book that says it:

I've seen where most Entrance terminal blocks have protection for analog circuits (CO line, Analog OPX) but require ones specified for use on digital sets.
