System for accumulating data over nondedicated telephone lines
First Claim
1. A telephone data accumulator system comprising:
- at least one selectively operable telephone data transmitting device at a remote location, said device including a data accumulator that accumulates data pertaining to services used at the remote location and means for generating a predetermined telephone dialing signal, both connected across non-dedicated telephone lines in parallel therewith so as not to interfere with normal service to a telephone connected across said lines;
line capture means connected across the telephone lines in parallel therewith at the remote location for seizing the telephone lines in preparation for placing a call;
means at the remote location for selectively conditioning said line capture means and generating means respectively on a time-selected basis to seize the telephone lines and to generate said dialing signals and apply said dialing signals to the telephone lines to thereby initiate a call from the remote location to a central location over the non-dedicated telephone lines;
a data utilization device at the central location;
means at the central location for automatically answering the call initiated from the remote location and producing a connection between the remote location and the central location over the telephone lines;
means at the remote location connected to the telephone lines for detecting a go-ahead signal on the telephone lines; and
,means responsive to said detected go-ahead signal for transferring data from the data accumulator at the remote location to the utilization device at the central location over the telephone lines connecting said remote location and said central location.

Abstract
A telephone data accumulator system for accumulating data at a central station through connection of the central station to a remote subscriber'"'"'s station, including a data accumulator, by way of nondedicated telephone lines. The remote terminal is selectively conditioned to generate dialing signals and to thereby provide selective connection of the accumulator to the telephone lines from the remote subscriber station. A preconditioning circuit such as timing means or a broadcast signal decoder at the subscriber'"'"'s station conditions the remote terminal and provides a short time window during a time of the day when the telephone there is not likely to be used for normal telephone calls, and the call is made to the central station during the time window to cause connection of the data accumulator to the telephone lines. The data in the data accumulator is thereafter transferred from the remote station to the central station over the telephone lines.

1. A telephone data accumulator system comprising:
-
at least one selectively operable telephone data transmitting device at a remote location, said device including a data accumulator that accumulates data pertaining to services used at the remote location and means for generating a predetermined telephone dialing signal, both connected across non-dedicated telephone lines in parallel therewith so as not to interfere with normal service to a telephone connected across said lines; line capture means connected across the telephone lines in parallel therewith at the remote location for seizing the telephone lines in preparation for placing a call; means at the remote location for selectively conditioning said line capture means and generating means respectively on a time-selected basis to seize the telephone lines and to generate said dialing signals and apply said dialing signals to the telephone lines to thereby initiate a call from the remote location to a central location over the non-dedicated telephone lines; a data utilization device at the central location; means at the central location for automatically answering the call initiated from the remote location and producing a connection between the remote location and the central location over the telephone lines; means at the remote location connected to the telephone lines for detecting a go-ahead signal on the telephone lines; and
,means responsive to said detected go-ahead signal for transferring data from the data accumulator at the remote location to the utilization device at the central location over the telephone lines connecting said remote location and said central location. - View Dependent Claims (2, 3, 4)

5. A system for accumulating data at a central station from data accumulators at a plurality of remote locations over nondedicated telephone lines connected to telephone sets at the remote location while minimizing the possibility of interference with normal telephone service to the telephone set comprising:
-
a selectively operable telephone dialing means and a data accumulator for accumulating data pertaining to billing for services used at the remote location connected to the nondedicated telephone lines at each of the remote locations; means at each of the remote locations connected to said dialing means for initiating the transmission of a predetermined pattern of sequential, periodic telephone dialing signals over the telephone lines to thereby place a call from the remote location to the central station over the telephone lines; means for selectively conditioning said initiating means at a time when the telephone set at the remote location is not normally in use in order to effect the transmission of said pattern of telephone dialing signals over the telephone lines and thereby initiate the transmission of telephone ringing signals to the central station; means at the central station for automatically receiving and answering the telephone ringing signals to place the central station in connection over the nondedicated telephone lines with the remote location initiating said ringing signals; means at the remote location for detecting the answering of the ringing signals by the central station; means at the remote location for transferring data from the data accumulator to the central station over the nondedicated telephone lines in response to said detecting means; and
,means at the central station for receiving and storing said transferred data.

6. A telephone data accumulating system for collecting billing data from subscribers to a pay television system, the billing data being collected at a central station from each subscriber station over nondedicated telephone lines that provide telephone service to the subscriber station, the system comprising:
-
a data accumulator for accumulating data pertaining to billing for television programs viewed at each of the subscriber stations; means including automatic dialing signal generating means at each of the subscriber stations connected to said nondedicated telephone lines for initiating telephone connection of the subscriber station to the central station over the nondedicated telephone lines; means for selectively conditioning said initiating means on a selection basis that is time determinable in order to effect the connection of the subscriber station to the central station over the nondedicated telephone lines while minimizing the possibility of interference with normal telephone service to the subscriber station; means at the subscriber station for effecting the transfer of data from the data accumulator to the central station over the connection made between the stations on the nondedicated telephone lines; means at the central station for receiving and storing said transferred data.
