atcomsystems.ca/forum Forums Other TDM Phone Systems 1A2 and Comkey Telephones & Systems Can you guess what this is?

The original was made by Melco...

If you can crack my code, I can crack yours

I suck at these things. I don't even know where to start or what I'm supposed to be looking for.

I thought it might be an exclusion unit.

That's the best guess by far, but still not it.

I thought someone would have gotten it by now.

Here's another clue. Sandman makes something very much like this, but it's not nearly as good. This device will trigger even if a call has been placed on hold, where Sandman's won't. (I know because I just used it to replace a Sandman unit.)

Ok. Since no one is biting, here's the PCB that finally arrived today. The printing on the corner should tell you what it is and what it does. It's a clone of a Melco device.

Never used them, just wired the set for control, unless I still don't know what it is.

This was used when you had a phone or device you couldn't rewire for A-lead control. Things like cordless phones, fax machines, and stuff of that nature.

I have my partner system behind my 1A2 system, so these work perfectly to give me A lead control when I'm on a partner phone, especially if I answer a call on a 1A2 set and place it on hold to take it on a partner set somewhere else. This will let me retrieve the call from hold on any other phone.

Super cool! Looking forward to seeing the result.

I don't remember ever wiring a fax behind a key system, doesn't mean I didn't. I remember banks of faxes with dedicated lines.
