Abstract
Abstract A telephone headset is connected to a telephone line through a interface module having programmable signal conditioning characteristics. The interface module is universal in that it can be programmed for use with many different headset or handset units. The interface module is automatically programmed through a multi-pin connector carried on the headset or handset connecting cable. The pin arrangement in the connector when plugged into a mating receptacle connector of the interface module produces binary input signals which can be decoded into programming signals for the signal conditioning circuit in the module.
