Hadn't thought about that, but yes, the alarm is likely grabbing the
line to inform the monitoring centre the power's out...

Could be, but he says that the sockets down stairs continue to work
normally. If it had seized the line then you would not expect this.
Maybe try having a phone plugged in upstairs while disconnecting the
power to that ring and listen to what happens, does something try to
dial out?

Does the alarm panel contain a dialler?
If it does is it plugged into a proper phone socket or has some one hard
wired it into the phone circuit some where?

My thought was that it had been [improperly?] connected to 'the
nearest available phoneline' which may have not been the main incoming
cable as the engineers suspected?

Daz,
I feel it might be time to very carefully trace the cabling and
see just where it goes and what else it connects to. The phone wiring
should not be connected to anything else and certainly not anything
connected to a ring main! As was suggested maybe a phone line extender,
although I thought those only regenerated ringing volts and would have
left 2 and 5 alone. Maybe not though.
Hopefully there is a simple explanation to it all and there is something
legitimate missing from your description but I'm not sure what at the
moment. Maybe the previous suggestion of "call an exorcist" would be
worth while?

I've traced the wire back from the rogue upstairs socket and it would seem
that it goes through the floor into the integral garage and then round the
edge of the ceiling into... the alarm unit.

I'm wondering if the fact that the reversed wire colours upstairs (blue with
white rings occupying the position at which white with blue rings appears on
the downstairs sockets) could be the cause of the non-ringing from the
upstairs socket (when used with my old cordless phone). "Does it matter if
A and B are interchanged" from http://www.gbnet.net/net/uk-telecom/p3-1.html
suggests that. The "can cause other problems" bit is a bit worrying! Which
problems would they be then? IS my ADSL connection likely to work from this
socket when I transfer it from my parents' address? And these extra two
wires are baffling.. I think they were actually white and pink... no bands.
They're not in the downstairs sockets but they come from the alarm and are
present in the upstairs socket.

I connected to the net via dial-up from the upstairs socket today and got
reasonable speeds (44Kbps I think).

The loss of the line upstairs when the upstairs power sockets are 'off'
doesn't really bother me I guess as I won't be turning the power off on the
whole!

That certainly could cause the 'no ringing' symptom, or possibly (If
you had another older phone with 3rd wire ringing plugged in)
continuous ringing or permanent off hook line state, or some
combination.

Another possibility is they simply haven't connected the ringing wire
through at all, and it's a red herring, this would also cause 'no
ringing'.

socket when I transfer it from my parents' address?

Depends on the phase of the moon I'm afraid, [not literally, but that
would be as accurate a guess]

Assuming you don't want to mess with the alarm wiring, and it all
seems to work, any possibility you could abandon this wiring and run a
nice new length of CW1308 or even Cat5? That would solve the problems
and leave the alarm functional (Although whether the unfiltered alarm
connection would coexist with ADSL is doubtful also).

Cordless phones don't usually take the ring signal from the 'third' wire.
Nor do many other modern types.


Here are the standard colours of cable, flex and their terminals.

Terminal Cable Cord Function
1 Green/white Orange Spare
Blue 2 Blue/white Red B wire (Line) -50v
Brown 3 Orange/white Blue Shunt wire. (Bell)
Green 4 White/orange Green Local earth (Not usually used)
Orange 5 White/blue White A wire (Line) 0v
6 White/green Black Spare
