Pager with both POCSAG and FLEX systems

摘要

A pager with both POCSAG and FLEX systems comprising a POCSAG decoder IC and a FLEX decoder IC; the FLEX decoder IC is connected to a microprocessor and the POCSAG decoder IC is built inside the microprocessor, a transistor based circuitry controlled by the microprocessor is between the 4 level IF receiver IC and decoder IC's, the signals and data are transmitted in 4 levels. The pager with both POCSAG and FLEX systems that can be used by different customers under different paging systems, manufacturers and retailers can also reduce the stocking cost for having two different pagers.
