A client is building a house and will have a barn about 600 feet from the house. Can he run a CAT5e that far and still have a phone system (probably Panasonic KXT624) work normally?
At what length do you worry about the length of CAT5e cables?

There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions. |

With questions like that I'll break oout a 1000ft box of CAT5E and terminate both ends. Keep in mind that over time the wire will have some loss, even think about running both ends in-out of a surge protector.

=Tom Since simple twisted-pair cables are used between central offices and customers, and even cross-country and trans-oceanic (before optical, of course), I don't think there would be a problem even if you used CAT-3, or even untwisted wire. Larry www.fineelectricco.com

The Panasonic 624 lists a maximum wire length for extensions in the install manual. I don't have one in front of me, but IF(big if) I remember correctly, the max run of cat5e was 750 feet. The spec changes with different wire.

CAT5E (e) if you believe the bullsh$t about the big e, versus little e, TIA Spec calls for max runs of 330' to maintain 100Meg data transfer...
I would think, for phone only purposes, that you could certainly run voice through 600 feet without much problem.
Further, TOTAL agreement with Larry here..., just found out today that a phone system install scheduled for next week has to be postponed because a lightening strike between two of the buildings has FUSED all of the network and voice cabling, ALONG with the conduit it was in, INTO one singular, molecular mess! All new wire must be pulled now!
The fusing and other weird shit of wire due to lightening might be unavoidable, but the damage it does at both ends IS manageable! As Larry said, and I confirmed today, surge protect BOTH ENDS, of anything that runs through the dirt (GROUND...yikes, how many problems do we have with GROUND???) and you should at LEAST theoretically save attached equipment!

Everything I read indicates the maximum run for CAT 5E is 350 meters.

It doesn't matter what the wire can do.
What matters is what the phone system allows.
Yes, twisted pair matters.
Each station phone needs four conductors; it pot needs two conductors.
Two quote Panasonic Installation manual, page 2-12:
a proprietary phone will run on 22 awg 1,180 feet
on 24 awg 750 feet
on 26 awg 460 feet
A pot will run 5900 feet on 22 awg
3700 feet on 24 awg
2290 feet on 26 awg
The doorphone can be run 590 feet with 22 awg
or 370 feet with 24 awg
or 230 feet with 26 awg
the door opener requires 22 awg, and it's maximum length is 590 feet.

Mitch, you should probably re-read the TIA specs for cat5e max run for a data use, to MAINTAIN cat5e data rating and performance is ~330 FEET, not 1155 feet (350 meters) I'm sure it will work for longer distances, but not as well... as for phones...I should think Fred knows best...e kinda has this THING for phone systems...it's almost unnerving sometimes! ;-) avdude

I want to thank everyone for the responses (especially avdude for the link that had what I was looking for).
avdude - Sorry that my initial search didn't pull up what I was looking for, I guess I used the wrong search key words when I first looked. I only came across this forum (actually I didn't know about the custom installer's lounge section) from someone else providing the link that pointed me the right direction. Thanks for your chastising and pushing me to use my noggin, getting started with this job there are so many areas that I don't feel I can do the job by myself (been out of work - corporate layoff in June '04) but have been looking to knowledgeable people who I can ask a few questions and get the answers which will get me over those rough spots of the unknown.
Again, many thanks to all for the wisdom of your experience!
Mike

Please read Fred's post, he's the only one who has your answer here. The phones may work at longer distances but the manufacturer only supports what is speced
