I thought the KSU I bought on eBay was the same type as my old shoe box that I had 20 years ago. frown
I had an old logic 10 that I thought I could use.

I was planning to buy and old Western Electric 2500 series 1A2 6-Button Touchtone Desk Phone and maybe an ITT 2564 six button desk phone.

Are they compatible?

What about my line cards are they ok for what I want to do?

I will look at the document over again. Hopefully I will understand.

20 years ago I was able to play with my shoe box with almost no problems. I could add lines and stations to the KSU.
I should be able to work things out if I just can understand the wiring codes.

I just looked at the layout for the 66R1, 66R2 and 66R3 blocks but I have reference where the CO lines are patched and where the stations are supposed to be. In my old shoe box all the pins were identified. Is there a document that gives me this information?
Thanks
