Question by Perry Trost posted 29 Jan 2005 | | RJ11 DSL Modem to RJ45 Wall Jack | When I first subscribed to DSL broadband in 1999,
my phone company installed a voice/data splitter
on my line in a switchbox outside of my apartment.
Inside, they installed a wall plate with an RJ11
jack for voice and an RJ45 jack for data. This
was a requirement then because the Orckit modem
provided at the time used standard CAT5 ethernet
cable between the wall plate and the modem. All
was good until my ISP went bankrupt and forced me
to find a new broadband provider. I now have a
new provider and a new Orckit DSL modem, but alas
this one requires a POTS RJ11 cable between the
wall plate and the modem! Also the 6' cable that
they sent me with the modem is too short to reach
across the room to the computer. (The old CAT5
cable was 25', 18' would have done the job but
the standard lengths then were 15' or 25'.) My
question: Since they split the voice/data signals
at the outside switchbox, is the RJ45 data jack
the only inside jack that will have data signal
on it? And if so, is it possible to buy a 20' or
longer cable with a male RJ11 plug on one end,
and a male RJ45 jack on the other, which would
connect my new Orckit DSL modem to the RJ45 wall
jack correctly? I presume Orckit changed their
modems because more homes are wired for RJ11, but
should I have to pay another $125 fee to have my
wiring changed back to RJ11 for my new modem?
Since the new 6' RJ11 cable won't reach anyway,
I'm hoping someone makes a 20' or longer cable
that will match my RJ45 data wall jack to my new
RJ11 based Orckit modem. If not, I'm looking at
a potential cost of $125 (or more) to have the
wall jack rewired again for RJ11!!!

Answer by Joseph Golan posted 13 Feb 2005 | Dear Perry,
Use your old RJ45 cable from the jack to the modem and then just purchase and install an RJ-45 coupler, female to female, (about $3-4) to couple the RJ45 cord to the RJ11 cord. The center pins of the RJ-11 will line up in the coupler to the center pins of the RJ45 which is where the signal will be.
Sincerely,
