Systems and methods for establishing a diagnostic transmission mode and communicating over the same
First Claim
1. A multicarrier transceiver comprising:
- a transmitter operable to transmit, or a receiver operable to receive, a first message requesting entry into a diagnostic mode, the transmitter further operable to transmit during the diagnostic mode a second message, wherein the second message comprises a variable indicating a margin value, the second message further comprises an array of Signal Noise Ratios per subchannel during initialization.

Abstract
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.
