I need some help from the 1A2 gurus.

I have an ITT K76A 1A2 system that I have in my house it works (still working on icm issues) but that is another issue.

My question is this:

I have a 4A speakerphone that came with an AT&T touch-a-matic 5 line phone.

Phone, speaker and control connect to an 82B connecting block. I connect the feed cable from the system and plug in the two transformers, that also connect to the 82B and everything works great.

I want to replace the touch-a-matic with the 2565 standard desk set. I went in an made sure the cables were connected in the set.

G-V -> 9
BR-V -> 7
V-BR -> 8
V-G -> G
S-V -> L1
V-S -> N

2565 works fine using handset.

push the on button on the 4A and it seizes line, speaker comes on but no dialtone. Push off and line is released. With speaker on pushing hold button drops line.

Any suggestions on what I am doing wrong, I am confused at this point.

I have the Key Systems manual, that is how I got wiring above.

Thanks in advance for help.

If you have the manual, I assume you have the transformer wired in correctly. You say you seize the line, do you mean you see the lamp come on or are you drawing DT but just not hearing it at the speaker?

Bill - I am assuming the transformers are wired correctly as they were connected to the 82B when I got it and everything works fine with the touch-a-matic connected instead of the 2565. When I say seizing the line I mean, I see the light come on and I can hear the 400D card click.

The only thing I see you didn't mention it to move the G lead off network terminal L2 and put it to network terminal F that is a switch hook contact.

Bill - I have taken a closer look. I have two G leads on network L2 one goes to dial pad and the other goes to the underside of the key buttons. I don't have an F terminal on the network. Any other suggestions.

If what I understand is correct, you have full control functionality, as in A-leads but just no audio to the 4A, correct?

Make sure that if this 2565 is a refurbished set that the correct dial is installed. It should have a Green/White and a Violet lead. Many times, refurbishers replace dials with standard non-speakerphone types not knowing any better. These leads bypass some switch hook functions when the buttons on the dial are pressed. Without them, the 4A can't work with the phone on-hook.

I think that these leads need to connect to the exact same two terminals that the white and green switch hook leads connect but I don't have my manuals or a set here at home to check. White/Green and Violet are connected together as long as any dial pad button is pressed. This basically tricks the phone's network that the handset is off-hook. Sometimes, phones get modified and not all connections end up where they are supposed to. There are many blind screws in these sets to use, so anything can happen.

One more thing: The line selected by the key strip comes out as terminal 9 (ring) and the mystery green lead that comes out from beneath the termial field (tip).

Hopefully, that's enough food for thought for the weekend. Check back early next week and I can give you better information.

You want the non dial green lead. Sometimes those network designations are hard to see. Not sure which manual you have, but I'm looking at note 3 in the Bell Key system manual. If anyone can get you going Ed can.

I think Ed may have touched on the problem. I do not have the dial that has the green/white and violet leads.

Bill - I found the F terminal and connected the green to it, but that did not solve it.

I am going to go through my other sets looking for a dial of the corret type. Any idea what the correct id for it is. The one in this set is labeled 35Y3D.

J gardner I have a 4a Speaker phone here in Wenham.
Being in Woburn why don't you give me a call or drop it off I'll make it work for you. Ive got all the Station specialty Western Electric books and lots of keypads and sets. If you can find an older Panisonic speaker phone with a-lead control its quite easy and better. I installed a lot of Panisonic speakerphones on Keysets many years ago in Polaroid. Like Ed said you need the right keypad and then the correct rewire or option in the set. You most likely will need the older western electric keypad with the spade tip connections under it.

IS that 2565 an ITT with 12 pr?
