Jeff, you weren't entirely incorrect. Generally, a "line" appearance, whether a CO or intercom, always had tip/ring (wh/bl) and lamp ground/lamp wh/gn) connection. In an effort to keep everything uniform, and since A leads weren't needed for an intercom circuit, the wh/or pair in the jumper was supposed to be unused.
The "purist" way as Sam mentioned was to not use the white/orange pair at all, although some carpetbaggers were known to use it for the buzzer pair.
I did this once or twice or.... :rolleyes:
The purist way is to not use the white/orange pair in the cross connect wire at all for an intercom appearance. I preferred to strip it completely out of the cross connect wire, but that's just me. A separate yellow/blue single-pair jumper was then used for the buzzer pair.
Sam:
You mean that all of your spools of jumper wire were actually still there when you returned? That ain't happening these days, that's for sure.
Oh, and the 415's were wired just like a CO line, A leads, ringing and all.
