Abstract

A telephone or two-way digital paging communication system providing an alternative partial communication format in which an acknowledgement signal is transmitted from a telephone device in response to a received voice or data signal. The communication system is switchable between different types of communication formats including full two-way voice or data service, partial two-way service and one-way pager service. The communication system may be implemented in a cellular network in which a portable cellular telephone is adapted to transmit signals at different transmission rates so as to increase its operable range.
