ABSTRACT:
A host telephone is connected by an interface to an accessory item. The accessory item is, for example, a cordless headset, a headset amplifier, a remote telephone dialing device, a cordless handset or some other device which is connected to a telephone. Two connectors are used to connect the host telephone to the interface. A first connector provides a standard headset connection to the host. The first connector propagates four signals: a transmit audio signal, a transmit return signal, a receive audio signal and a receive return signal. A second connector provides a propagation media for additional signals. The additional signals provide additional communication links between the host telephone and the accessory item.
