Metal Lath is a classic for Key ground. I've got to remember that one. I remember having to pull a separate cable once to get Remote Hold working because the local ground s*cked. (As I recall - a 6B, a 17B, an 18D KTU and 1/2 of a good CSV circuit per line). I'm shuddering as I remember it. My foreman said that you couldn't call yourself a telephone man till you could get remote hold working. No sooner had I done my second one than they came out with remote hold cards that replaced all the relays. When I did my first job with the cards (Sanbar somethings... I can't remember the number) I couldn't believe how easy it was.
Matt -
Tone the cable back and ID how many pairs you have good to the frame. Like I said, 2 lines and an Intercom with buzzer can work on 6 pair and an earth ground. It can be done. It's not for the faint of heart, but we'll talk you through it.
Does your cuckoo clock phone have the little 66 blocks inside or does it have an amphenoled cable?
