Re: ADSL + PSTN over CAT5 cable

["Chris Miles" <chrismiles@xxxxxxxxxxxxxxxx>]

I dont want to send the full unfiltered signal on one CAT5. I need to
see BT first about getting the old style socket
converted to a NTE5 line box. I then want to split my ADSL and PSTN right
at the master socket and send off
independently (through a faceplate filter) - without compromising my ADSL
signal strength.

After the master socket and any ADSL microfilters, PTSN needs 2 pairs
(only half of the second pair is used though, for the "bell"
signal),
and ADSL a single pair. So you could fit 2xADSL + 1xPTSN on a single
cat5 cable.

If the ADSL connection is sharing a line with the PTSN, you could put a
microfilter at the far end and send the unfiltered signal down one pair.
You still need half a pair for the bell signal, but you will have 2
pairs left for additional ADSL signals.
