Woha! Look what I found!!! Coolness!

565 wiring diagram

That's the BSP for a 565. It is different from a 564. Want me to fax one over to you?

Look for the number of the actual key that is in the phone. Is it a 589H or a 636A?

That site has a lot of BSP's...good information.

Arthur,

I had to wire it as a 565, because amp connector on the cord I bought does not have jumpers soldered onto it, daisy-chaining the LG's.

In any event, I already rewired it according to the diagram, and everything seems to be working fine, however, it would be great if I could get the diagram for the 564 as well. Thanks for the offer!

I'll pm you my fax number.

Jeff,

You're welcome

"because amp connector on the cord I bought does not have jumpers soldered onto it, daisy-chaining the LG's."

In that case, would I be able to daisy chain the LG's on the 66 block? :idea:

BTW, does anyone have a MOH KTU? Are these programmable, or is one just stuck with whatever music the manufacturer stuck on it?

There are two basic types (at least)of MOH KTUs. There is the ITT 403 that is an isolator card. This lets you have MOH without getting crosstalk on the dialtone lines. Most 400 cards require a KTU of this type. Some don't (I don't remember off hand which ones don't, but they're rare.) Some systems (The WE Comkeys I believe) had this isolation built in, but I can't speak to it as I never really worked on them. The WE & ITT 400Es did need the 403.

The 403 would not plug in to a normal 18 pin slot. If you didn't have a panel with 20 pin slots (most didn't) you had to add a 359 (single) or 259 (double) 20 pin adapter panel (or similar).

Then you have the SanBar FM radio card, that was an FM tuner on a 400 type mounting. Plug it in and pick your favorite FM radio station.

Some of the early "fancy" Japanese 1A2 type systems had a built in MOH. The Tie 1030 (Grey Whale) had a thing that looked like it came out of your grandmother's music box. It played anything you wanted as long as it was "Annie Laurie".

Ask away. I'm amazed I can remember any of this stuff.

I'll ask the other Cranky Old Timers to double check me. Please. I think I remember this stuff and then I begin to doubt myself.

Does my KSU 551 have 18 pin slots? Could I use an ITT 403 on my KSU? And what kind of music does it play?

I would prefer really tacky elevator music.

How about this little guy:

451 KTU

I believe the 451 is the WE version of ITTs 403. Arthur is much more up to speed on WECO stuff, he'll hopefully chime in soon.

Your 551 has 18 pin slots. Again these units do not provide the music source, only the isolation. Any source, including a transistor radio will work. Clip the bud off a earphone jack and hook that up.

If you only provide music to line 1 you can skip the isolation card.
