It includes VDSL2 access unit used to connected user side terminal device, traffic processing unit used to process transmission and split recombination, center processing unit used to detect terminal device. The invention processes split recombination for the ADSL terminal by user side terminal device to make one VDSL2 access device port support ADSL and VESL2 device terminals, satisfy the demand of ADSL user side terminal in existing network.
Description
Technical field
The present invention relates to network service, relate in particular to implement device and its implementation of a kind of dynamic support ADSL and VDSL2 terminal.
Background technology
Along with the development of broadband network, the broadband user sharply increases, and the xDSL access technology has obtained to use widely as one of broadband access method main on the current market.The developing direction of broadband network is the flattening structure of being close to the users, and number of nodes is with showed increased, and the node capacity is to middle-size and small-size development.Therefore, only can't finish the rational deployment of broadband network, need the middle-size and small-size equipment of increasing high-performance by the large capacity equipment that is applicable to intensive covering.
The VDSL2 technology provides solution for the middle-size and small-size equipment of the needed high-performance of the network topology of this flattening.The VDSL2 technology is a kind ofly brand-new to tell xDSL technology, and bigger bandwidth can be provided, and can support the accesses network of all-around service to use, and comprises data, video and voice.The characteristics of this technology are that transmission rate is fast, coverage short, the rate-compatible self adaptation, and can be configured to symmetry and asymmetric two kinds of transmission modes as requested.
Compare with VDSL, VDSL2 is enhanced on the performance again, and the part characteristic is similar with ADSL+, for example forces to support the Trellis coding, forces to support multicarrier (DMT), forces to support 15bits constellation mapping, convolutional interleave, INP etc.Because it has used for reference the technical characterictic of ADSL2, and has adopted the coded system of DMT, makes it become possibility from the compatible ADSL user side of access protocol angle terminal.Angle from the xDSL model change, when VDSL2 equipment is replaced the adsl equipment of existing network, still have the demand that requires novel VDSL2 equipment to provide support in a large number, and the VDSL2 access unit of present most types can be realized and the collaborative work of ADSL user side terminal to the ADSL user side terminals of a large amount of deployment of existing network in early stage.
Yet when user side equipment is the ADSL terminal, because the encapsulation of the link of early stage ADSL is ATM cell, and present VDSL2 access product demand is exchanged for the master with Ethernet, and ATM cell can't directly exchange on the operational processor of Ethernet exchange kernel, must at first convert the Ethernet bag to exchanges, so for ATM and these two kinds of packaged types of Ethernet, the requirement of the requirement of its Business Processing and data flow conversion is different, and demand and business development along with broadband access, multi-services operation and exchcange core IPization are basic requirements, so will on VDSL2 equipment, realize support, need implement device and its implementation of a kind of dynamic support ADSL and VDSL2 terminal to the ADSL terminal.
