Any Idea how to wire this?

[Westrex]

Why would you want a 4-prong.plug when you already have a 44A connecting block?

I saw a new credit union building with 3-pair Station wire installed for these. No busy lamps, but at least they had neon line lamps to indicate which line to answer., and had access to all 3 lines.

If possible, I would like to use the original connection block, as I just listed modular & 4-prong connections as examples to hook up to a PABX or Key Telephone System. If there is a way to hook up the phone to a PABX or Key Telephone System, that would be better.

According to AE Circular 1934,
https://www.telephonecollectors.info/index.php/search/basic-search?q=AE_Circular_1934_Oct59_AE-87
The AE 87 does not require a KTU.  You just connect it to up to 3 lines, and you are ready to go.  You could use your POTS for one line, an XLINK to your cell for another, and an ATA for a third if you want.  Or you could connect it to 3 PBX extensions if you want to.

If that mini PBX you linked to above does not support rotary, the Panasonic 308 and 616 definitely work with rotary, and there is a discussion subsection under key systems on this board.

Thanks for the information SUnset2, I'll try the 3-line method first, then I'll try the KTS.

Wouldn't I still have to wire up a jack (or a few) to hook it up to all 3 things (One for the POTS line, one for a Xlink or something, and the other for something else)? In that case, how would I wire it to connect to these things, since the AE 87 was hard-wired (as far as I know)?

Yes, you will have to connect it to whatever type of dialtone source that you decide use. You have already been provided with a wiring diagram that shows the connections that you will need to do that. When I have time I will expound further or perhaps someone else will in the interim.

Here is another wiring diagram that highlights the terminals inside of your set that would need to be connected to for each of the incoming lines from whatever D.T. source you decide on. You can connect them at the terminal strip located inside of the telephone (shown) or at the other end, on the connecting block that were shown in your earlier photographs. You have already been provided with both a link to AECo TB-498, as well as a jpeg excerpt of one of its wiring diagrams.

Also, I'm not sure where you got the idea that a external KSU would be needed since I had previously provided links to both AECo TB-398 and AECo Circular 1934, both of which extol the Type-87's virtues of being self-contained without the need for an external control box (KSU).

However it is true that other external units would be needed to enable other features such as busy lamps, an internal intercom, line exclusion and ringing on the other two lines. If you decide that you want any of those additional features, we can address them once you have already made your desired D.T. connections.

[G-Man]

There are several ways to connect your telephone set to whatever sources of D.T. that you decide on. 

If your PBX or other devices are nearby, a half-modular telephone cord would be sufficient. 

Plug into your D.T. source with the modular end and then connect the spade terminals on the end of the Red and Green wires to your connecting block. 

My previous post specified the terminals to connect to. 

If you don't want to use the half-modular cables, then an alternative would be to remove the wires from the connecting block and terminate them on standard, RJ11 modular jacks.

 You can then plug one end of a standard full-modular cord into a jack and then plug the other end into your PBX or other device. 

You can also hardwire from the connecting block to the source device and terminate the wire at that end with modular jacks that can be used with a short RJ11 cable to plug into the device. 

There may be other options as well but you will have to more specific as to what you want to accomplish.

Here are a couple of photos of a half-modular cord.

Thanks for the reference image G-Man. I did not know cords like that existed before. I'll get to wiring after I order the cord.

I usually make my own half-modular cables, usually from modular cables I pick up cheap at garage sales.  All you need is some insulation piercing crimps and a crimper.  The thread below discusses the crimpers:
http://www.classicrotaryphones.com/forum/index.php?topic=4071.45
I got my crimper and crimps on Ebay.  I got two sizes of crimps; the older wires need a larger crimp.  It is indispensable for repairing damaged hard-wire cables.  If you don't have one, you should consider getting a modular crimper, for repairing broken modular connectors, or making cables any length you like.  The cheap ones are OK.  Westrex, PM me if you want a demonstration.

I do need a crimper to repair a damaged cord on the Tongya TY-006 pay phone I own. I'll look into crimpers as well.

For ease of access & repairability, I'm going to connect the half-modular cords to the connection block.

Try this:  attach a line cord, with the yellow wire going to terminal 3, the red wito terminal 1, and the green wire to terminal 6.  Only catch is that my house has grounded ringing, so it may not ring if you don't.
