Abstract:

In a ratio paging system of the type having digital data modulated onto radio signals transmitted from a radio station to receiving units at remote sites, a test system. The test system includes a transmitter test module coupled to a radio transmitter at the station and a test bed module located at the remote site. The transmitter test module includes a microprocessor for generating digital test data, and a modulator coupled to the microprocessor for modulating the test data onto a radio signal and for injecting the radio signal into the station transmitter. The test bed includes a receiver for receiving the modulated radio signal, a demodulator for demodulating the received radio signal to recover the digital test data, and a computer for processing the recovered digital test data to generate paging test information. The mobile test bed also includes means for determining the latitude and longitude of a site to generate digital location data which is used to generate test information. The test system further includes a mobile vehicle for transporting the test bed, a power supply in the vehicle for providing power to the test bed, and means for determining the distance travelled by the vehicle to provide a test sampling rate.

Abstract:

A paging system and method utilize a trunk interface module which is capable of recognizing unique identification numbers, which comprise the telephone number which a caller dials to reach a particular paging receiver. The relative-digit-independent truck interface module is located between the telephone company central switch and the computer in the central clearing house and is capable of recognizing and relaying a set of at least seven digits, which comprise the unique receiver's identification number, wherein the values of the digit and the identification number are completely random, i. e. , the digits are not necessarily representative of telephone numbers/identification numbers, in a particular telephone exchange. The system also includes a separate inward dialing portion which does not use the interface module and which requires the manual entry of receiver identification numbers.
