Converter to put analog line through structured cabling ?

Posted on 2006-04-28
Last Modified: 2010-03-19

Other than purchasing tools and crimping myself - is there some adapter I can get, effectively to put an analog line (in this case a fax) through structured cabling and back out again at the other end?

Not sure how else I explain this - well I have an analog line close to a patch panel not being used and rather than put a long extension through the building to where I would like to use it, I would like to take advantage of the structured cabling which routes to the correct location. This would also make it easy to move in the future should the need arise.

    If by structured cable you are referring to category 3, 5, 5e, or 6 UTP or STP cable and if by analog line you mean a Plain Old Telephone Line (POTS), then yes, just pick a pair of wires in the UTP/STP cable and use the same ones at both ends.

    You can plug an RJ-11 mod jack into an RJ45 female (8 position 8 conductor) jack.  Your analog POTs line should ride the blue pair through the structured cabling where you plug an RJ-11 into the other end to pull the signal out to the device.

    No problems, easy peasy.

    of course... there are adapters that can help you with that.  I haven't got the exact product, but here are some links to manufacturers:

    you can google for rj-45 splitters or y adapters...

    of course, you can always do the crimping yourself... you could use the blue pair or the brown pair if you don't use gigabit ethernet...

    ahh, of course... didn't refresh on time... sorry pseudocyber... anyway, you can use a splitter if you need the cable to use both ethernet and analog voice =P

    Using the existing CAT5 and patch panel connection to simply connect your analog FAX line is fine as suggested by several others, but never use a splitter of any sort for Ethernet. They exist, and you will get connectivity, but an extreme amount of cross-talk, and reduced performance, if it works at all.
