In a paging system that includes a system controller, an active repeater, and a backup repeater, data integrity during a repeater transition is assured. As each repeater receives a stream of paging information from the system controller, the repeaters store it. When the repeater transition occurs, the backup repeater determines the paging messages that were not transmitted during the repeater transition based on the most recently stored stream of paging information. Subsequently, the backup repeater transmits a paging failure message to the system controller indicating the paging messages that were not transmitted. Upon receiving this, the system controller commands the backup repeater to retransmit the paging messages that were not transmitted during the repeater transition.

Method for assuring data integrity during a repeater transition

A paging simulcast station remote control system decoder. The paging system decoder responds to signals generated in accordance with a predetermined signalling scheme comprising a series of tones and timed pauses. The decoder is also responsive to user programmable switches which provide station function tone and sector information. The paging system decoder then selectively deactivates a paging simulcast transmitter in response to signals received through a conventional paging communication link.

Individual simulcast station control decoder

A paging station remote control system decoder is described. The paging system decoder is responsive to signals generated in accordance to a signalling scheme comprising a series of tones and timed pauses generated by a paging system encoder. The paging system decoder then causes a paging transmitter station to key in an analog or binary modulation mode or to switch from one mode to another without first dekeying the paging transmitter.

Paging universal remote control decoder

A paging station remote control system capable of providing analog or binary modulation modes is described. Control of the paging base station is effected through a signalling scheme comprising a combination of tones and timed pauses generated in response to control signals supplied either manually or by a paging terminal. The paging system is capable of transitions between binary and analog modulation modes without first dekeying the paging transmitter.

Paging universal remote control system

A simulcast paging transmitter remote control system capable of individual station control is described. The remote paging transmitter control system comprises an encoder and decoder which interface with a paging terminal and transmitter respectively. The system encoder and decoder communicate through a specifically formatted signalling scheme which is configured to provide station deactivation information as well as conventional paging information.
