Problems solved by technology

[0008] Regardless of which of the above three technical solutions is adopted, the uplink still relies on Asynchronous Transfer Mode (ATM) transmission equipment or Internet Protocol (IP) transmission equipment, so the communication system line needs to invest in the construction of a relatively expensive transmission network
If the existing DSLAM equipment adopts E1 UNI / E1IMA / E3 uplink, or uses FE electrical interface / GE electrical interface uplink, because the transmission medium is cable or Category 5 line, the transmission distance is relatively short, and the DSLAM equipment cannot be extended. , for some remote areas cannot meet the needs of their broadband services; if the optical interface is used for uplink, or E1 UNI / E1 IMA / E3 is used for uplink transmission through SDH / PDH, fiber optics need to be laid, which is for some Where there are no optical transmission resources, it is necessary to lay optical fibers or increase optical transmission equipment, which will require a lot of manpower and material resources

Embodiment Construction

[0044] In order to make those skilled in the art of the present invention understand the present invention more clearly, a detailed description will now be given in conjunction with the accompanying drawings and embodiments.

[0045] Figure 4 It is a structural block diagram of DSLAM equipment in the present invention, such as Figure 4 Shown, DSLAM equipment comprises among the present invention:

[0046] The user-side broadband service processing module 10 is used to process the broadband modulation signal from the user side, i.e. the XDSL signal, and convert it into an uplink data flow. The data flow can be ATM data, Ethernet data or For TDM data, send the data stream to the demultiplexing / multiplexing processing module 12 for processing; at the same time, it is used to receive the downlink data stream sent from the demultiplexing / multiplexing processing module 12, and convert the data stream into a broadband modulation signal That is, the XDSL signal is transmitted thro...

Abstract

The invention discloses a digital subscriber line access multiplication device. It includes subscriber side wideband service processing model, splitting and multiplexing model, memory, network side process model. The invention extends the multiplexing device with a long distance, thus the transmission distance an be prolonged; at the same time, to the places without fiber and idle optical transmission resources, it needs not to use large amount of human power and object to lay fiber or increase optical transmission device, and it can cater the wideband service demands. The invention also discloses the transmission method for the digital subscriber line access device.

Description

technical field [0001] The invention relates to a communication system, in particular to a digital subscriber line access multiplexing device of the communication system and a signal transmission method based on the device. Background technique [0002] In recent years, with the development of communication network technology, the speed of my country's communication network construction is very fast, most areas have opened communication system transmission equipment, but due to financial, technical and other reasons, the overall coverage of communication system transmission equipment is not yet very high. After nearly a hundred years of development, ordinary twisted pair wires have become very mature in technology, and at the same time the price is very low. . Therefore, the use of ordinary twisted pair for signal transmission is a very good technology for remote areas where transmission equipment has not been opened. [0003] Digital Subscriber Line (XDSL) technology is a...
