Abstract

The invention relates to an expansion-rate symmetrical?high?bite?digital?subscriber?line (SHDSL) transmission module and belongs to the technical field of modulation and demodulation. According to the expansion-rate symmetrical?high?bite?digital?subscriber?line (SHDSL) transmission module, a management information interface (4) and a control unit (1) are connected with each other; an expansion service interface (5) and a data interface (2) are connected with each other; the control unit (1) and the data interface (2) are both connected with a symmetrical?high?bite?digital?subscriber?line (SHDSL) processing unit (3); and the symmetrical?high?bite?digital?subscriber?line (SHDSL) processing unit (3) and a loop interface (6) are connected with each other. According to the spreading-rate symmetrical?high?bite?digital?subscriber?line (SHDSL) transmission module of the invention, an expansion rate transmission technology is adopted, and therefore, point-to-point 64kbit / s-to-15296kbit / s bidirectional net load rate transmission for 1 to 16 km can be realized on one twisted pair with low energy consumption.

Description

Technical field: [0001] The invention relates to the technical field of modulation and demodulation, in particular to an extended rate SHDSL transmission module. Background technique: [0002] For broadband access technology, people are more familiar with ADSL (Asymmetrical Digital Subscriber Line), which can establish an asymmetrical digital communication link of up to 896kbit / s and downlink of 8160kbit / s on a pair of ordinary twisted pair lines. Road, which is very suitable for Internet access and asymmetric services such as VOD. But it is precisely because of the asymmetry of the ADSL rate that there are many limitations in the application of ADSL. In particular, the commercial broadband demand environment is a two-way, symmetrical traffic environment, and the tolerance for performance fluctuations is relatively low. ADSL access technology has been increasingly unable to meet people's demand for bandwidth and traffic. So, people began to pay attention to SHDSL technolog...
