It is, but pinouts vary enormously even when it's just the analogue

Of course. Unless an international standard individual countries choose
their own connectors, etc. No different from mains or whatever.

I lived / worked in six European countries (Norway, Sweden,
France, Germany, Italy, Switzerland) plus the USA and the UK throughout
the 1990's and I always had to cart around a bunch of adaptors to cater
for the laptop for fax / fledgling internet / dial up company network
access. Plugging an analogue dial up modem into a digital only line in
your hotel room doesn't work either

PABX's that permit analogue phone and 'digital' featurephones have their
own unique methods of connection. Mix that with the BT interface (4 and
6 wire versions) or RJ45 sockets and plug in adaptors to the local phone
connector standard and it's very easy to get no connection, or no
incoming ringing. A multimeter helps to some extent

The exchange in question works with standard phones. Which isn't to say
they won't need the correct connector fitted.

SO)ME progress.

Instead of using te tip and ring pair that proviode normal analogue
phones on usual BT pins, I switched them to the other set of pins.

The phones are now partially live and I can hear dial tones in the
handset BUT there is a backround whoosh whoosh noise.

And they are not communicating with the PABX. Can't ring anything and
they register as permently off hook if I try to ring them...

I doubt you'd get the phone plug to fit the mains socket though

But it's no wonder the UK is just about the safest place for mains electrics.

Somewhere, possibly Denmark was rumoured to be the place that stopped 4mm
speaker plugs. Presumably because of unshuttered sockets and a nation that only
used plastic knitting needles. Copenhagen Airport is the limit of my travels in
Denmark, the SAS business class bar with the pumps on the customer side of the
bar and the multiple deicings of aircraft in the depths of winter being the
extent of my memories of the place.

Yes that's probably more accurate, but i've always called them RJ11's same as
I've always called all similar looking 9, 15, 25, 37 and 50 pin connectors 'D'

Just to complicate things there was also the MMJ plug used on VAX's that was

IIRC somebody or other (don't remember who) used that plug with the
offset clip as a DC supply connector for an answering machine I once had.

Well I finally spent 10 miunutes with a meter and have now given up.

Basically the pins that should go to line pins had 25V DC on them and
made the phone come half alive when connected to pins 3 & 4 insread of 2
& 5 as is correct for an analogue phone.

The only other pairs that had any voltage on them, were then applied to
the 2 & 5 pairs. Both polarities wre tried. The phones didnt work digitally.

Unless pins 1 & 6 are in play I cant see anywhere else to go.

Unless anyone has any other ideas its pack them, up and get a refund

I have an ancient Panasonic KX-TA624 wired as three into 8...

So I bought a job lot of KX-T7750s and a KX-T7730 ...

But they don't seem to work no matter what wires I connect.

Does anyone know chapter and verse on the compatibility of
these?

What was the point of buying a job lot if you didn't have any
idea if they were compatible? Wouldn't it be better to think
it through first.

Oh dear. According to all the websites - and I spent 4 days
checking - they WERE compatible.

Not everybody is as stupid as you Pam.

Your foolishness is that you bought them but you can't make them
work.

Know your limitations and leave this sort of thing to someone who
knows what they're doing.

Gotta smile that someone who claims to have all the electronics
experience that Turnip does can't get a phone working.

In a way, I'm surprised TNP isn't posting about some deep and
meaningful electronics theory and how the phone designers were too
stupid, lazy or incompetent to design something he could use without
getting help.

Why? It's a simple question. Pnasonic support vclaims that model of
phone is compatible with that model of PABX. There are only 8 possible
combinations of 2 pairs of wires . I have tried them all. The phones
don't work. I just want confirmation before I return them as
incompatible.

Or broken.

What a mess. Sounds like you're out of your depth.

No Pamela, It ddoesn't. It sounds like you unpleasantt vindictive side
is showing again.

The question is merely one of establishing that these phones do or do
not work with this particular PABX which they are clained to do.

It seems that they do not.

However being not the sort of arrogant bitch that you are, I always
allow that I could have made an error and ask around.

Are the phones working yet?

I have no idea. They will be returned.

I see you are still on your troll trip.

Does a standard BT phone work with your PSBX? Are the phones you've bought
suitable for connection to a BT line? Obviously with any wiring or
internal strapping etc being correct.

Still no.
