I recently posted asking about disconnecting line 3 from the phone
wiring to reduce interference to my ADSL connection.  Well, for the
few sad people who are interested, I finished playing with my phone
lines just now and I have an AMAZING increase in speed.  Only time
will tell if I stop losing the connections as I used to.

I changed ISP to Sky from Andrews & Arnold. (Same money but now I have
all 6 sky packages and ADSL2).  This is not the reason for the
betterment, because when I first conected to Sky a few days ago on the
*unchanged* house wiring I was getting just 4400 kps.  Then this
morning I got some filters from ADSLnation in the post and set to with
the little screwdriver.

https://secure.adslnation.com/products/index.php

I have an XTE 2005 faceplate filter that goes on the master socket.
Any extensions from there have the ADSL signal filtered out, except
for a single extension that goes up to the small bedroom with the
signal included.  There an XTF85 divides the ADSL from the phone and
the Sky router is plugged in.  From here all further extensions can be
filtered from the signal too.  This means no more dangly filters.
Neat.

No Line 3 (ringer) connections are made at all.

Now I'm getting a DownStream Connection Speed of 10389 kbps.  Whacking
increase, necst' pas?  Well worth it.

It does - each filter has its own ring capacitor on the phone outlet
side.

Most modern phones don't rely on the power on line 3 any more.  As
long as they see a signal (or something. No, I don't know how exactly)
on the line then they decide to ring, or play a tune, or warble...

The incoming line is only 2-wire.  I thought the 3rd (internal only) wire
was the "anti-tinkle circuit" that stopped an extension tinkle ringing as
you dialled-out (pulse not mf) on the main phone or vice-versa.  It's also
used by old answerphones to stop them taking the call if it's picked-up by
another extension.

Well, I'm not a phone engineer, so I just looked it up out of
curiousity.  (I bet the formatting goes tits up!)

"Internal Cabling
Conn No.    Usual Cable Colour    Carries

1     N/A                                          No connection
2     Blue with White Bands       Speech and Ringing
3     Orange with White Bands  Ringing
4     White with Orange Bands  Not used but usually connected for
neatness
5     White with Blue Bands       Speech and Ringing
6     N/A                                          No connection"

"A common complaint is that one phone will work in an extension yet
another plugged into the same socket won't.  Usually this is because
either the extension has been wired up with only terminals 2 and 5
connected or 3 has come adrift.  Some phones originally designed for
the overseas market will accept a ringing signal on 2 and 5 only (they
usually only have those two wires connected) and so will work, others
designed to use pin 3 for the ringing circuit won't ring but they will
dial out and you can speak on them."

I'm bored now.  It works for me.

A note of caution: it's fairly common when provisioning ADSL2+ to set
customers on an artificially low line speed for a few days to allow
the MSAN/DSLAM to collect some line stats, before finally setting a
safe upper limit for you.  You would need to disconnect or reset your
modem to see the new higher speed.  This might be what just
happened ...

I did wonder if something like this would happen, but the difference
was immedieatly after the socket changes.  I had disconnected the
modem several times in the few days before while tidying cables,
moving things around etc and it hadn't affected the speed.

Whatever, I'm happy. :)  Well, nearly.  Just to be on topic:  I STILL
haven't got the bike back from Nash's workshops.  Sob.

The interesting bit is that SKY is ADSL2. BT need to catch up.

Bit of a double-edged sword.  It's great for people on short, high-
quality copper loops, but the benefit is marginal for people on longer
lines.  There are, or certainly were 12 months ago, some fairly major
compatibility issues between certain DSLAMs and certain brands of
modem.  Then there's the economics of ripping out all your old DSLAMs
and replacing them.  Much easier to do if you're building out from
scratch as Sky/Easynet have been doing...

I wonder if they are using Alcatel Isam's ?
