Interesting sites!

My dentist is still using a 25-pair (1A or 1A2) key system installed by Pacific Bell probably in the late 1970s. I asked his daughter who owned the equipment today. She thought her dad does, but didn't know for sure. I hope he isn't still paying at&t for monthly rental.

My friend's vet is using a 25 pair system too. It looks like ITT gear.
