Can someone briefly explain a "ring-down circuit"? Client currently has an Inter-Tel system that I am replacing with an MICS. As is set-up now, client pushes a CO line and line immediately starts ringing @ client's home office. Home office answers as they would any call from an outside line.

This sounds, to me, like speed-dial or "hotline", but client insists it's called a "ring-down circuit" which they pay extra (and dearly) for from MaBell.

Thanks in advance,

Some fire and police, airport auto rental still have ringdowns installed. I'm sure there are others. You complete the loop by going off-hook, the CO does the dialing. It is a "hotline" as you know it and ringdowns are expensive. In the older CO's they were quite common. I would question anybodies motive for having a ringdown these days.

Thank you. That's what I wanted to hear. I cannot understand the reasoning for a ring-down circuit if speed-dial or hotline will do the same thing (for free!).

I would understand if the circuit connected the caller to home office via the tel. system (e.g. - intercom to intercom).
