Embodiment Construction

[0040] With reference to the accompanying drawings, figure 1 It is a schematic diagram of the network structure showing the salient features of the conventional asymmetrical digital subscriber line ADSL system. Such as figure 1 As shown, an ADSL system can be constructed using a DSLAM 40, a DSLAM manager 50, an ADSL transmission unit receiver ATU_R 60 and a splitter (not shown). The configuration of this ADSL system is representative of a conventional xDSL system.

[0041] The DSLAM system 40 is set as an access node of an access network such as the ATM network 10 and the public switched telephone network PSTN 20, and performs the function of aggregating subscriber lines 40a, 40b. The ADSL subscriber receiving / transmitting unit ATU_R 60 is located at the end of the subscriber line to perform a data receiving / transmitting function between the DSLAM system 40 and the subscriber 70 . In addition, a splitter (not shown) is provided between the DSLAM 40 and the ATU_R 60 to filte...

Abstract

A multi digital subscriber line access multiplexor M-DSLAM system, connecting with an asynchronous transfer mode ATM network, l inking with multiple data transmission service networks, and multiple subscriber receiving / transmitting units to perform subscriber line collection function and enable a wideband high-speed data receiving / transmitting operation among the numerous subscribers, The M-DSLAM system incorporates multiple ATM cell buses, an NIU, multiple xDSL service unit, a shelf interface unit SIU, and a main control unit MCU. Therefore, the M-DSLAM system can provide a wideband high-speed data service system, that supports high capacity processing ability and various services including a dialogue service with motion picture, such as a videoconference, a video medical service, VoD, and a voice service based on voIP. This M-DSLAM system advantageously enables on a substantial increase in the number of subscribers while significantly reducing the area occupied by the M-DSLAM system.

Description

technical field [0001] The present invention generally relates to multiple digital subscriber line access methods and multiplexer systems (ie, M_DSLAM systems) using an asynchronous transfer mode (ie, ATM) network as a backbone network, and in particular, the present invention relates to processing procedures and multiple digital subscriber line (DSLAM) systems. Subscriber line access method and multiplexer system capable of providing various broadband high-speed data services with high capacity for multiple users connected to corresponding points of M_DSLAM system. Background technique [0002] In general, Digital Subscriber Line (ie, commonly referred to as "DSL") is capable of providing broadband high-speed data services bi-directionally to a home or office over ordinary telephone wires made of metallic copper twisted into pairs. [0003] There are various types of DSL, often collectively referred to as xDSL, such as Asymmetric Digital Subscriber Line (known as "ADSL"), H...
