A method for communicating data from one or more remote computerized coin telephone auditing devices to a central computer via a telephone line, which comprises the steps of receiving input data signals at a remote computerized auditing device, decoding the input data signals into digital data, and processing and storing the data signals. The digital data are then retrieved. The processing, storing and retrieving steps are accomplished by reading and writing the digital data from volatile memory to a non-volatile memory, and from non-volatile memory to volatile memory. The digital data is coded into corresponding output data signals, and are transmitted to the central computer via the telephone line. The receiving and transmitting steps are accomplished by the exchange of a predetermined sequence of data signals, whereby the remote computerized device and the central computer correctly identify each data signal. Finally, the method periodically disrupts the method for a predetermined time period, whereby power consumption by the remote computerized device is temporarily disrupted.

A method of communicating external source data from one or more remote programmable auditing and monitoring devices for a coin telephone system to a central computer via a telecommunications link, comprising the steps, performed cyclically and continuously of: (a) determining whether an off-hook data event has occurred, if so then: (i) receiving external source input data signals at the remote programmable device; (ii) decoding said input data signals into digital data; (iii) processing said digital data; (iv) storing said digital data; and if not then; (b) determining whether a reporting event has occurred, if so then: (i) retrieving said digital data (ii) coding said digital data into corresponding output data signals; (iii) transmitting said output data signals to the central computer via the telecommunications link; and if not then: (c) disrupting steps (a) and (b) for a predetermined time period, whereby power consumption by the remote programmable device is temporarily disrupted, by: (i) counting time intervals; (ii) halting steps (a) and (b); (iii) storing previously received input data; (iv) waiting until a number of time intervals equals said predetermined time period; (v) retrieving said stored input data; and (vi) returning to step (a).
