    Hi,
    Is there any reference material (books, websites etc) available that
    guides an electronics designer to comply with FCC part 68 rules while
    designing telecom interfacing circuits? It would be ideal if the
    reference material explained the aspect by providing typical example
    circuits. Basically, my requirement is to design an answering machine
    with automatic dial out feature. Please help

    Thanks a lot,
    Nav.

    Look for Code of Federal Regulations 47, Part 68.

    Your answering set will need to meet all the appropriate requirements of Part
    68. You might want to look for a "Conformance Lab" to test your product when
    it is ready.

    Document ANSI T1.401-(year of last issue) would be helpful also. It's title is
    "Interface Between Carriers and Customer Installations - Analog Voicegrade
    Switched Access Lines Using Loop-Start and Ground-Start Signaling." The
    American National Standards Institute is in NY.
