The system comprises a conventional paging signal reception means which receives and processes in a manner described more fully below RF paging signals caused to be transmitted from a conventional RF paging system not shown by host processor Method and system for monitoring and transmitting utility status via universal communications interface. Also shown in FIG. Network provides impedance matching at the central frequency of the spread spectrum signal exiting the mixer between the output diove of the mixer and the input impedance of the automatic gain control and low pass filter network The data to be transmitted is temporarily stored in the data memoryand controller then commands the processor to cause the switch datasbeet connect the reception network to the antennaand the controller waits a predetermined time bg126 to ascertain detect whether another i.

Preferably, the baseband frequency used in such decoding and for encoding data desired to be transmitted from the device by the processor is 4. Modem 30 then transmits the data to cellular tower 48 A using a modem-ready cellular transceiver. Also, disadvantageously, this system is unable to automatically read non-machine-readable meters, and is only able to automatically read machine-readable meters.

The particular utility vy126 will stagger such transmissions by its total population of customers bby126 the billing cycle, the end result being that SFS 24 will receive data each day corresponding to a portion of the utility company’s customers.

The spread spectrum signals exiting the impedance matching network enter the networkwhich includes an automatic gain control portion not shown which receives the signals exiting the networkand a low pass filter network not shown which receives the signals exiting the automatic gain control portion of the network Thereafter, the controllers and imaging devices are either commanded by the host processor to return to sleep mode, or automatically return thereto.

Such personnel may then use user interface means to command administration controller to command database to transmit the requested report files to the converter In this embodiment, the RMP is a self-contained unit which houses data acquisition, processing, control, memory, and data transmission circuitry.

When real time clock 80 reaches a preselected time stored in one of the alarm registers, it sends an interrupt request signal or IRQ down PC bus 62 to main board 70 and more particularly to microprocessor This answer window is also programmed into the RDUs.

All calls that come to the RDUs during the answer window, whether from the UDP or a third party, are detected through ring detection circuitry, which then prevents the telephone from ringing inside the customer premises.

The data is then sent to SFS 24 through a virtual connection over wide band link When controller supplies enable signals to mixermixer up converts the smoothed spread spectrum signals supplied thereto, using the carrier mixing signals, to generate up converted spread spectrum signals with a primary frequency of MHz plus or minus 6.
