That is a remote control unit and requires a DC telco pair, not a POTS line.

That's correct. The T1611, like Will said, is a DC remote. It requires a "dry" pair - just a pair of wires from the T1611 to the termination point at a base station. POTS has DC and some type of signalling on the pair so is not useable.

I appreciate all the help on this..guess i'll trash it,just asking myself why someone would go to the trouble of installing a rotary phone dial on a unit that would not accept it.....strange!...would have made a great conversation piece.

Would be interesting to find some kind of manual or paperwork on this unit to see what it was intended to be used for...oh well

The T-1611 was used for the HEAR -Hospital Emergency Administration Radio - system that was an emergency radio link between hospitals. The dial was part of a selective signaling system to alert a particular hospital.

It did not in any way interface to a standard phone line. It was meant to control a remote radio base station over a dedicated circuit.

It is indeed a "conversation piece" but only for display.

The rotary dial on the remote sends a audio tone that is interrupted by the dial contacts to the remotely located transmitter.

And some of the HEAR radios were located in the elevator equipment room on top of the hospital... very dirty job servicing the station. And one was in the ceiling above the PBX with three feet of headroom...

The remote control console was usually in the Emergency room.

This link fully describes the system. The dial is for the "IPS Code".
