DSL Splitter - house wiring question(s)

Hi All,

I'm in the process or rewiring all of the low-voltage circuits in my
house (cable, phone, network). My question(s) are concerning my DSL
hookup.

Originally, every phone jack in my house ran from the jack to the
"network interface" (NI) box on the outside of my house. I have just
a single incoming phone line (phone number), but my DSL runs through a
splitter in the NI box. With the original wiring, the single in-house
jack that the DSL modem plugs into was hooked to the "split" DSL line
outside.

Now, with my new wiring, I have just a single CAT5e cable running
outside the house and connecting at the NI. I wired the main phone
line as "line 1" and the split DSL line as "line 2". That single line
now goes to a central wiring location in the basement where it's used
as input to a Channel Vision C-0437 telephone distribution module,
which can be seen here:

I plan to move my DSL modem to the basement, right next to the C-0437
module. Now, I'm wondering what's the best way to get the modem
connected to the incoming "line 2" circuit? I guess I could make a
patch cable that goes from the modem's RJ-11 jack to one of the
C-0437's 12 output jacks, and push line 2 to line 1 in the wiring of
the patch cable, but is there a better way? Actually, I'd prefer to
not even eat one of the 12 output jacks of the C-0437 for this, as I
really need to use them elsewhere in the house.

Ideally, it'd be nice to split line 1 and 2 apart at the C-0437 end of
the Cat5e cable, before it's used as input into the C-0437. That way,
only line 1 would feed into the C-0437, and I could plug line #2
straight into my DSL modem. Does such a splitter exist? What I
really need is the ability to take an RJ-45 with line1/line2, and
output line 1 to an RJ-45 (for input into the C-0437), and line 2 to
an RJ-11 (for input into the DSL modem). I assume such a thing could
be cobbled together from store-parts, but again, is there a better
way?

I guess I could have brought the DSL line in from outside on a
separate wire, which would have eliminated this whole thing (though
that seems wasteful), or I could have split the in-house side of the
single Cat5e into an RJ-45 and an RJ-11 in the basement (but that
seems ugly).

Any advice on how this *should* be done would be greatly appreciated.

Thanks,

Jeff

Isn't this what the "whole house" DSL filter does ?? All you did
was move it inside.

Reed,

Thanks for the reply, though after thinking on this last night, I
think I now have a good solution. This seems to have been a "can't
see the forest for the tree's issue.

Anyway, I think I'll just snip off the RJ-45 end I placed on the
incoming CAT5e cable, and replace it with a dual RJ-25 jack (actually,
1 RJ-25 and 1 RJ-11) at my structured wiring location. Then, I'll run
lines 1, 3, 4 from the CAT5e (with line 1 being my voice line, and 3,
4 not being used) into the RJ-25 jack, and line 2 (my DSL line) into
the RJ-11 as line 1. Then, I can make a cable with an RJ-25 end and
an RJ-45 end to go between the 3-line jack and my C-0437 distribution
center and another cable (RJ11 -> RJ11) to go from the single line
jack to my DSL modem.

Phew - that sounds ugly in writing, but seems simple enough in
practice... ;^)

Anyway, thanks again for the input.

Jeff
