I was wrong about the handset wire colors. They are the same as a line cord. Green, Red, Yellow and Black. I have not seen a handset with these color wires before. Is this normal? How would I hook it up? I will have to see if the volume is better once I get this wired in.
Thanks.

Telephone Troubleshooting and Repair / Re: 3554 ISSUE

Last night I worked on this a bit. First, I hooked it up to my Panasonic without doing anything and it worked fine. Dial tone, rings & dials out. He said it did nothing at his house but made his other phones not work. He has a 500 I gave him years ago that has always worked fine. I moved the hook switch slate wire from A to L2 and now I get a fast busy signal. I will have to compare the wiring diagram you posted to the phone tonight and see if it matches.

Interesting to see this dial with French lettering and the (apparently original) LMT card on a French type 24 phone!

3554 with 2-wire ringer on the right.
3554 with 4-wire ringer has the ringer connected the same as in the NE 500/554 on the left, except that the black ringer wire should go to L1 rather than G.

If you leave the slate wire on A, with the 4-conductor ringer connected as in a 500, then when the phone is on-hook, L1 is connected to A through the hook switch contacts "a" and "b. "Thus, the 2650 ringer coil would be shorted whenever the phone is on-hook.

I just got it back. Unfortunately I gave it to him before I saw your message about moving the hook switch wire. I am going to do that tonight. Thanks!

Interesting dial maker's card, LMT was one of the 2 french ITT subsidiaries (the other one being Thomson-Houston).

Harry, did you get the phone to ring without ring trip?

There was a 20p version with a couple of different components in the coin mech but 40 years later I can't remember whether it was sold or was only a prototype.

New Member Introductions / "Mr Moneybox"
Last post by Tony Whitley - Yesterday at 10:15:30 AM
Hi all,

I wrote the software for the "Moneybox" payphone (which involved a fair bit of input to the mechanics and electronics) back in 1984/5.  Prior to that I worked at GEC writing the software for their offering for the BT street payphone tender (won by Plessey which was a nasty shock as we didn't know they were tendering).

The attractions of payphones were eclipsed by the new kid on the block, cellular phones, and I moved to Technophone and spent most of the rest of my career writing mobile phone software.

I still have the engineering model Moneybox and the source code listings are in the attic! I have many war stories from those days, if you're not careful I may post some of them. As a taster: we wanted to test the coin mechanism for weaknesses so ordered (from memory) £3,000 of 10p pieces from the local bank.  This was an unusual request which took quite a while to fulfil! When they finally arrived I opened them up to find they were all newly-minted where we wanted used coins to see the effect of dirt build up; we returned them the same day and expressed our requirements more precisely which must have made us the bank's least-favourite customer  >:(
