Abstract
A modular telephone handset (100) comprises an earpiece (102), a mouthpiece (104), and a handle (106) detachably attached at one end to the earpiece and at the other end to the mouthpiece. Attachment and detachment is effected by snap or twist joints (108,110). This allows one of the earpiece and the mouthpiece when detached to be used by a human user for listening or talking on a telephone call while simultaneously allowing the other of the earpiece and the mouthpiece to be used for receiving or transmitting data with an acoustic coupler (202) of a TDD device (200), thereby facilitating mixed-mode TDD-and-voice communication at any telephone that is equipped with the modular handset.
