Systems and methods for establishing a diagnostic transmission mode and communicating over the same

A method for communicating data between modems using multicarrier modulation comprising:

• instructing a transmitting modem to forward an initiate diagnostic mode message to a receiving modem;
• determining a diagnostic link message;
• transmitting the diagnostic link message;
• and
• determining the accuracy of the transmitted diagnostic link message.

A method for communicating data between modems using multicarrier modulation comprising:

• receiving an initiate diagnostic mode message;
• determining a diagnostic link message;
• transmitting the diagnostic link message;
• and
• at least one of increasing a transmission power of the diagnostic link message if the received diagnostic link message is inaccurate and re-transmitting the diagnostic link message a predetermined number of times.

A method for communicating data between modems using multicarrier modulation comprising:

• receiving an initiate diagnostic mode message;
• determining the accuracy of a received diagnostic link message;
• and
• receiving at least one of an increased transmission power diagnostic link message if the received diagnostic link message is inaccurate and a re-transmission of a predetermined number of the diagnostic link messages.

An information storage media comprising information for communicating data between modems using multicarrier modulation comprising:

• information that instructs a transmitting modem to forward an initiate diagnostic mode message to a receiving modem;
• information that determines a diagnostic link message;
• information that transmits the diagnostic link message;
• and
• information that determines the accuracy of the transmitted diagnostic link message.

A method for communicating diagnostic information between DSL modems using multicarrier modulation comprising:

• completing a portion of a modem initialization sequence;
• transmitting an initiate diagnostic communication mode message to a receiving modem;
• entering a diagnostic communications mode based on at least one of an initialization failure, a bit rate failure, a CRC error in an initialization message, a CRC error during the normal steady state transmission mode, a forward error correction error, a user request, a central office modem request and a remote terminal modem request;
• and
• transmitting a diagnostic link message comprising at least one of a version number of a diagnostic link mode, a length of the diagnostic information, a communications standard, a chipset type, one or more vendor identifications, an ATU version number, a time domain received reverb signal, a frequency domain reverb signal, an amplifier setting, a CO transmitter power spectral density, a frequency domain received idle channel, a signal to noise ratio, bits and gain information, and upstream and downstream transmission rates.
