Abstract:
1. A method of providing a phone line communication system, comprising: providing powered circuitry and phone line side circuitry, the phone line side circuitry configured to be coupled to a phone line, the powered circuitry and phone line side circuitry configured to allow communication between the powered circuitry and the phone line side circuitry across an isolation barrier; configuring at least one of the powered circuitry or the phone line side circuitry to generate a serial digital bit stream, the serial digital bit stream including at least data bits; configuring at least one of the powered circuitry or the phone line side circuitry to transmit a plurality of the data bits across the isolation barrier as part of the serial digital bit stream, at least some individual data bits of the plurality of the data bits being provided to be transmitted multiple times across the isolation barrier; configuring at least one of the powered circuitry or the phone line side circuitry to receive the serial digital bit stream, the receiving circuitry including error correction circuitry; configuring the error correction circuitry to receive the individual data bits that are provided to be transmitted multiple times; analyzing the multiple transmissions of the individual data bits to detect the presence of an error; and generating an error corrected version of the individual data bits if an error is detected.
