Tone generating apparatus for a cellular telephone simulates those tones normally sensed by a user of a conventional land-line telephone. The cellular telephone is adapted to communicate with a base station via a service provider which provides different types of service, such as HOME service, ROAM service, or alternate HOME service. A progress tone generator is actuable to generate for the user selected dial tone indications as a function of the detected type of service provided by the service provider. In addition, when the keypad of the cellular telephone is operated, digit tones identifying the actuation of the respective keys are generated as is digit data which represents those keys; the digit data being transmitted to the base station to dial a respective telephone number. A warning indication, such as a distinctive tone, is generated in the event that the digit data does not represent a valid telephone number.

A system and method of displaying incoming pager messages on a receiver using infrared signals. The paging device includes a receiver for receiving paging signals including paged information. The output signal from the receiver is supplied to a baseband processor where it is converted into a digital signal, under the control of a processor. If the thus digitized signal is determined to be the selecting signal for the particular paging receiver, the digital signal is then preferably sent directly to a protocol translator, where it is converted into a signal having an infrared protocol. After processing in the protocol translator, the signal is then sent to a transmitter and transmitted as an infrared signal. The infrared signal is then received in a light-receiving element in a receiver where it is thereafter decoded by a protocol decoder in accordance with instructions contained in a memory connected thereto to retrieve the paging signal or paged message. The receiver has a display for displaying the decoded information and preferably has an indicator for confirming receipt of the infrared signals in the receiver.
