Upon detection of a trigger, such as the exceeding of an error threshold or the direction of a user, a diagnostic link system enters a diagnostic information transmission mode. This diagnostic information transmission mode allows for two modems to exchange diagnostic and/or test information that may not otherwise be exchangeable during normal communication. The diagnostic information transmission mode is initiated by transmitting an initiate diagnostic link mode message to a receiving modem accompanied by a cyclic redundancy check (CRC). The receiving modem determines, based on the CRC, if a robust communications channel is present. If a robust communications channel is present, the two modems can initiate exchange of the diagnostic and/or test information. Otherwise, the transmission power of the transmitting modem is increased and the initiate diagnostic link mode message re-transmitted to the receiving modem until the CRC is determined to be correct.

1. A system for communicating data between modems using multicarrier modulation comprising: an initiate diagnostic mode trigger that instructs a transmitting modem to forward an initiate diagnostic mode message to a receiving modem;a message determination device that determines a diagnostic link message; anda receiving modem diagnostic device that receives the diagnostic link message and determines the accuracy of the diagnostic link message, wherein the diagnostic link message is re-transmitted a predetermined number of times. 2. The system of claim 1, further comprising a power control device that increases a transmission power of the diagnostic link message if the received diagnostic link message is inaccurate. 3. The system of claim 1, wherein the diagnostic link message is re-transmitted the predetermined number of times with or without a change in transmission power and the predetermined number of times is several times. 4. The system of claim 1, wherein the diagnostic link message comprises at least one of test and diagnostic information. 5. The system of claim 1, wherein the diagnostic link message comprises 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 (ADSL transceiver unit) version number, a time domain received reverb signal, a frequency domain reverb signal, an amplifier setting, a CO (central office) 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. 6. The system of claim 1, wherein the accuracy is determined based on at least one of an error detecting scheme, a bit error detection and a cyclic redundancy check. 7. The system of claim 1, wherein the trigger is based on at least one of an initialization failure, a bit rate failure, a CRC (cyclic redundancy check) error in an initialization message, a CRC error during a normal steady state transmission mode, a forward error correction error, a user request, a central office modem request and a remote terminal modem request. 8. The system of claim 1, wherein the transmitting modem completes a portion of a modem initialization sequence before forwarding the initiate diagnostic mode message. 9. The system of claim 1, wherein the transmitting modem is at least one of a central office modem and a remote terminal modem. 10. The system of claim 1, wherein the receiving modem is at least one of a central office modem and a remote terminal modem. 11. The system of claim 1, wherein the receiving modem determines channel measurement information during a diagnostic mode. 12. The system of claim 11, wherein the channel measurement information comprises at least one Signal-to-Noise ratio measurement for one or more subchannels of the system. 13. A modem for communicating data using multicarrier modulation comprising: transmitting, by a transmitter portion of the modem, an initiate diagnostic mode message; andreceiving, by a receiver portion of the modem, a diagnostic link message and determining the accuracy of the diagnostic link message, wherein the diagnostic link message is re-transmitted a predetermined number of times. 14. The modem of claim 13, wherein the accuracy is determined based on at least one of an error detecting scheme, a bit error detection and a cyclic redundancy check. 15. A modem for communicating data using multicarrier modulation comprising: a receiver portion of the modem that receives an initiate diagnostic mode message;a message determination module in the modem that determines a diagnostic link message; anda transmitter portion of the modem that transmits a diagnostic link message, wherein the diagnostic link message is re-transmitted a predetermined number of times. 16. A method for communicating data using multicarrier modulation comprising: transmitting, by a transmitter portion of a modem, an initiate diagnostic mode message;receiving, by a receiving portion of the modem, a diagnostic link message and determining the accuracy of the diagnostic link message, wherein the diagnostic link message has been re-transmitted a predetermined number of times. 17. The method of claim 16, wherein the accuracy is determined based on at least one of an error detecting scheme, a bit error detection and a cyclic redundancy check. 18. A method for communicating data using multicarrier modulation comprising: receiving, by a receiver portion of a modem, an initiate diagnostic mode message;determining, by a message determination module in the modem, a diagnostic link message; andtransmitting, by a transmitter portion of the modem, a diagnostic link message, wherein the diagnostic link message is re-transmitted a predetermined number of times.
