Hi

About to setup on ADSL and need advice on the line-splitters please. Sorry
if the questions are stupid - but you have to start somewhere.

a) I presume they only have to be installed into extensions actually used -
yes? no?
b) In my home the BT master-socket isn't actually used directly (i.e. no
phones plugged into it), but there are two extensions that are wired in from
behind (by a previous owner, but checked by BT after we moved in). Would
this cause problems in any way?
c) We have Sky TV, and the Sky box plugs into the phone line via one of the
above extensions (as does a telephone) - with a splitter installed into that
extension, would Sky be connected to the voice bit of the splitter or the
data bit?

Cheers

theyr'e not stupid! but the correct term is "filter", not "line-splitter".

yes.

shouldn't do. however, it's possible that the wiring to them might not be
100% perfect and could cause signal reduction, which could affect the
speed you can get out of your adsl connection. plugging the adsl
connection into the original bt socket, might give better results in this
case. however, if they've been checked by bt, they ought to be ok.

i don't know anything about sky boxes, but anything that was connected
into the phone line before adsl was activated should be plugged in to the
voice bit of the filter. the only thing that should be plugged into the
data bit of the filter should be a single adsl modem or router (i.e., only
one data socket on each telephone line should have have a plug in it).

It's best to call them microfilters rather than line splitters.

Yes.

No.

Voice.

Nothing goes on the data side except your ADSL modem or router.
Everything else must be connected via a filter.

If it has two outputs it could also be called a splitter. Only the Voice
side is filtered. The ADSL/Data side is just a straight pass-through.

There are also filter models available with just two RJ11 sockets (one on
both ends). These are more popular in the US where all phone sockets have
RJ11 connectors. Using these you have to connect the modem and phone in
separate extensions or use a separate RJ11 splitter.

Indeed - though the reason I was suggesting not calling them splitters
was to distinguish between a splitter that is just that (two or more
plugs into one socket), and a "splitter" that contains a low pass filter
to filter out ADSL signals.

Surely only if the outputs are identical?
