Abstract
Abstract A paging system operably connecting remote paging receivers with an incoming call and having substitute paging numbers assignable to the remote paging receiver. A first digit selector connects the incoming call to a two digit selector after the appropriate fifth digit of a seven digit number has been inserted into the first digit selector. The sixth and seventh digits of the seven incoming signal are then routed to the two digit selector which is connected to tone generators which produce pairs of tones assigned to the sixth and seventh digits. The pair of tones is routed through a dial-a-spare panel which is operable to substitute a second pair of preselected tones for the first pair of tones. A selector finder is connected to the two digit selector and when transmitter time is available connects the incoming trunk lines of the first digit selector to the transmitter via a terminal assembly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
196 words
A paging system adapted to be connected to a radio base station transmitter which allows incoming calls from a dial telephone to be directed to a new receiver substituted for an inoperative receiver when the dialed digit address of said inoperative receiver has been inserted into said system via said telephone, said inoperative receiver being activated when operative by a given pair of tones whereas said new receiver being activated by a substitute pair of tones, comprising: tone generators being arranged to generate tones which include said given pair of tones and said substitute pair of tones; digit selectors connected to said tone generators and being operable to distinguish said dialed digit address and to then select said given pair of tones from said tone generators; first means connected to said digit selectors and said tone generators operable to select said substitute pair of tones from said tone generators and replace said given pair of tones with said substitute pair of tones assigned to said new receiver; and, selecting means connected to said digit selectors, said first means and said transmitter and operable to direct only said substitute pair of tones to said radio base transmitter.
Claim 2
Dependent Claim
196 words
A paging system adapted to be connected to a radio base station transmitter which allows incoming calls from a dial telephone to be directed to a new receiver substituted for an inoperative receiver when the dialed digit address of said inoperative receiver has been inserted into said system via said telephone, said inoperative receiver being activated when operative by a given pair of tones whereas said new receiver being activated by a substitute pair of tones, comprising: tone generators being arranged to generate tones which include said given pair of tones and said substitute pair of tones; digit selectors connected to said tone generators and being operable to distinguish said dialed digit address and to then select said given pair of tones from said tone generators; first means connected to said digit selectors and said tone generators operable to select said substitute pair of tones from said tone generators and replace said given pair of tones with said substitute pair of tones assigned to said new receiver; and, selecting means connected to said digit selectors, said first means and said transmitter and operable to direct only said substitute pair of tones to said radio base transmitter.
Claim 3
Dependent Claim
120 words
The system of claim 1 wherein: said first means has a switch assembly with a pair of first switches, a pair of second switches and a relay with control means, normally opened contacts and normally closed contacts, said normally opened contacts are connected between said second switches and said digit selectors and said normally closed contacts are connected between said tone generators and said digit selectors, said first switches operably connect said control means to a source of electrical energy when said given pair of tones are received by said first means including said normally closed contacts, said second switches are connected to said tone generators receiving said substitute pair of tones and are connected to said normally opened contacts.
Claim 4
Dependent Claim
67 words
The system of claim 2 wherein: said digit selectors are a first digit selector and a plurality of two digit selectors connected thereto, said first digit selector has a pair of incoming trunk lines and a stepping switch operable in response to a first pulsed signal of said dialed digit address on said lines to connect said lines to a vacant one of said two digit selectors.
Claim 5
Dependent Claim
45 words
The system of claim 3 wherein: said vacant digit selector has a pair of stepping switches operable in response to a second and third pulsed signal of said dialed digit address on said lines to direct said given pair of tones to said first means.
Claim 6
Dependent Claim
34 words
The system of claim 4 wherein: said vacant two digit selector has a switching relay operably connected to said selecting means, said switching relay directs said substitute pair of tones to said selecting means.
Claim 7
Dependent Claim
34 words
The system of claim 5 wherein: said selecting means has a selecting stepping switch operable to connect said lines to said transmitter when said substitute pair of tones are received by said selecting means.
Claim 8
Dependent Claim
20 words
The system of claim 6 wherein: said first means has a plurality of said switch assemblies connected together in series.
