Wired data and voice remote transmission module and implementation method thereof

Abstract

The invention discloses a wired data and voice remote transmission module and an implementation method thereof. The method comprises the steps that a line modem is adopted for accomplishing link construction of a wired link; a CPU (Central Processing Unit) performs program initialization on the line modem; and an FPGA (Field Programmable Gate Array) processing unit performs program processing on Internet access data, serial port data, voice data, a dipper second-generation pulse per second signal and a level signal. Service interfaces of the module are rich; an Internet access, a serial port, a voice port, a dipper second-generation pulse per second interface, and a level signal interface are arranged; and a single chip solution is adopted, so that power consumption is low, a wired data and voice remote transmission rate is high, and a wired data and voice remote transmission distance is long.

Description

technical field [0001] The invention relates to communication transmission technology, in particular to a wired digital voice remote transmission module and its realization method. Background technique [0002] G.SHDSL.BIS technology is a high-speed wired transmission technology system recently launched by the International Telecommunication Union. It is an upgraded version of G.SHDSL technology. The supported rate ranges from 192Kbps to 8192Kbps. It is compatible with the previous G.SHDSL technology system and has Higher transmission rate, stronger anti-interference ability, longer transmission distance and other technical characteristics. [0003] The wired digital voice remote transmission module using G.SHDSL.BIS technology makes full use of the technical characteristics of G.SHDSL.BIS, uses Infineon's PEF22628 chip as the basic transmission chip, and completes the initialization of the chip through the LPC2478 processor. The signal conversion and processing of the Ethe...

AI Technical Summary

Problems solved by technology

[0004] 1) The existing G.SHDSL cable transmission technology has a low rate (rate range 128kbps~2048kbps);

[0005] 2) The existing equipment using G.SHDSL technology has a single interface, generally only Ethernet interface or voice interface;

[0006] 3) Existing equipment using G.SHDSL technology is generally divided into two parts, the analog front-end (AFE) circuit and the data processing (DSP) circuit, such as Conexant's GS2237 and GS3137 chip sets, due to the use of dual-chip Design, high power consumption (2W);
