Abstract

The invention discloses an ADSL (asymmetrical digital subscriber line) bandwidth aggregation method, comprising the following step of: binding two telephone subscriber lines together to use in a pair, wherein one telephone line is configured to be used according to the international telecommunication union G.992 ADSL standard, the ADSL bandwidth aggregation method is characterized in that the other telephone line is configured to be of an opposite uplink / downlink transmission direction of the standard configuration to be used, namely, a terminal device of one subscriber is arranged on one side of a telecommunication station machine room of the telephone line, and an outside interface of the terminal device and an outside interface of a station end access module of the regular telephone are bounded to be used in parallel together; and one one-way digital subscriber line station end access module is arranged on one side of a subscriber resident of the telephone line, and an outer output interface of the station end access module and an outer interface of the subscriber terminal device of the regular telephone line are bounded to be used in parallel together. Simultaneously, the invention further discloses an ADSL bandwidth realizing system and an access device.

Description

technical field [0001] The invention belongs to a method for a user terminal to access a communication service network and its implementation system, in particular to an implementation method and system for increasing the transmission bandwidth of a wired digital subscriber line. Background technique [0002] The most commonly used broadband access technology is the Asymmetric Digital Subscriber Line (ADSL) technology at present. The most advanced ADSL technology is the enhanced second-generation ADSL technology (ADSL2+) standardized in 2003, which can provide data transmission broadband with a maximum downlink speed of 24.4 Mbits per second and an uplink speed of up to 3.5 Mbits per second within a range of 5 kilometers. [0003] It is called ADSL because the technology uses frequency division multiplexing to send and receive data simultaneously on a single telephone line. Such as Figure 9 , Figure 10 As shown, it can be seen from the spectrum diagram that the uplink (s...
