Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a broadband user access processing method and equipment, and a user interface board. Background technique [0002] xDSL is a high-speed data transmission technology transmitted over telephone twisted pair (unshielded twisted pair, Unshielded Twist Pair, UTP), in addition to IDSL (ISDN Digital Subscriber Loop) and SHDSL (Single Pair High Bit Rate Digital Subscriber Line) In addition to DSL (Digital Subscriber Line) for baseband transmission, xDSL for passband transmission uses frequency division multiplexing technology to enable xDSL and traditional telephone service (POTS) to coexist on the same pair of twisted pairs, where xDSL occupies the high frequency band, POTS (traditional Telephone service) occupies the baseband part below 4KHz, and the POTS signal is separated from the xDSL signal through a splitter. xDSL for passband transmission uses discrete multitone ...
