 Wiring from Patch Panel to Jack
I have come into a situation where I have to run Voice and data on the same CAT5. Voice uses one pair. The other three are left. How do I wire the last three pairs to the jack and to the patch panel? How many pairs does and ethernet connect actually use?

Dear Francine,

Split sheath use should be discouraged as it kills the concept behind "Structured Cabling". That being said my best recommendation is to cut down all 4 pairs at the patch panel and jack. Then use a "splitter" to break it out to two jacks like the Siemon YT4-E2-U2 (see this url)

Some folks do not like this method and insist on splitting the cable, so use the wiring diagram of this splitter to terminate the cable on two jacks at the station and connect the wh/Or and Wh/Grn pairs only at the patch panel. Cut down the the remaining two pairs on a block for voice.

The two data pairs can not be used Gigabit ethernet but you should be able to run 10BaseT or 100BaseT.
Sincerely,
Joseph Golan, RCDD
