Phone use kills DSL connection, even with whole-house splitter Charles Wahl 09-24-05

Well, I installed a whole-house splitter, thinking that my problem was
with the dongle-type splitter that my ISP provided with DSL modem; but
using the phone on the same line that the modem is on still terminates the
DSL connection.

Details:
Phone service is Verizon, via UTP wiring installed to my apartment within
the last two years. Wiring on the Telco side in the NID is sort of
haphazard (wires not twisted right up to the screw-terminals), but I'm
reluctant to mess with them. Screw terminals have red and green wires to
the gray module in the NID that has the user-side screw terminals (also
red and green).

I've used a Cat5 cable to connect each of the two phone lines in the NID
to a 2" x 3" electrical outlet box just below it, containing (only)
Leviton snap-in RJ-12 jacks; done carefully, with spade connectors on the
NID side, punchdown on the jacks.

Cat5 cable with RJ-12 plugs connecting the DSL line from jack to a Wilcom
PS-15 whole-house splitter.

Cat5 cable, again with RJ-12 plugs from splitter to DSL modem. Linksys
WRT54G wireless-capable router (wireless disabled) connected to DSL modem,
and serving our home network (again, all Cat5).

All phone wiring downstream of splitter is Cat5, installed by me, and star
topology, though that doesn't matter, since I get the same results if I
connect our phone direct to Wilcom splitter. I can get dial tone, and
dial, without losing the DSL connection, but as soon as ringing begins on
the line being called, the connection drops. DSL light on modem relights
when phone use is complete, but it takes awhile for the router to

The phones we're using are 2.4 GHz wireless models, if that makes a difference.

Can anyone hazard a guess as to what might be causing this, despite my
best and careful efforts? I was vigilant to keep to the USOC and T568A
color codes while making up connecting cables, but I might have swapped a
tip/ring pair in the phone cables; could that cause this annoying problem?

Thanks,

Did you test per my advice in your previous thread? This didn't sound like
a "cheap splitter" problem to me, ever.

Something wrong with your server then.... see my previous 9/16/05 post,
