Abstract
A transceiver with a plurality of components coupled to one another to form a transmit path and a receive path for multi-tone modulation of user data across a communication medium. The transceiver includes a framer and a deframer. The framer is configured to momentarily suspend framing of user data before processing bits associated with tones targeted for reference data transport and injects the pre-agreed reference pattern therein, after which framing of user data resumes. The deframer is configured to momentarily suspend deframing of received user data bits before processing bits associated with tones targeted for transport of pre-agreed reference data and extracts the received reference bits thereof for comparison with the corresponding pre-agreed reference bits to determine errors therein, after which deframing of user data resumes.
