Embodiment Construction

[0041] The invention integrates various services such as broadband access and telephone on the CATV network.

[0042] Referring to the system shown in Figure 2, the system mainly includes:

[0043] Broadband access equipment: used to connect the telephone network and IP network;

[0044] Integrated convergence module: including Ethernet switch, connected with broadband access equipment. The upstream data flow of the integrated access module is aggregated, and sent to the three-layer switching equipment and NGN voice switching platform through the upstream data optical port for processing; the downlink data sent by the broadband access device is forwarded to the integrated access module.

[0045] Optical receiver: Receive cable TV optical signals and convert them into radio frequency signals.

[0046] RF amplifier: Amplifies the RF signal output by the optical receiver.

[0047] The optical receiver and radio frequency amplifier are set in the integrated convergence module, ...

Abstract

The invention is a method and system for providing wideband accessing and telephone service on wired television network. The method is: when in downstream service: each kind of digital subscriber line signal transmitted to user and analog voice signal are blended into the first mixed signal to be transmitted; the received first mixed signal and the wired television signal are blended into the second mixed signal, and it is transmitted to the user terminal side through radio frequency cable; the second mixed signal is separated into data signal, voice signal and radio signal for user. In upstream service: the data signal and analog voice signal transmitted by user are blended into the third mixed signal, and transmitted through radio frequency cable; the third mixed si8ngal is transformed and forms the fourth mixed signal and transmits; the transformed signal is separated into data signal and analog voice signal, and the data signal is demodulated and transmitted to the exchange device, and the analog voice signal is converted into IP voice signal and transmitted to the exchanging device.

Description

technical field [0001] The present invention relates to broadband network technology, in particular to a method and system for providing broadband access and telephone services on a cable television network. Background technique [0002] A cable television system (CATV) is a system that provides users with multi-channel images, sound broadcasting and data signals in a wired manner within a certain area. [0003] After the mid-1990s, with the progress of society and the development of technology, the cable television system has developed rapidly in the direction of large-scale, multi-functional and multi-service. In addition to basic radio and television programs, various new technologies and new services such as optical fiber technology, bidirectional transmission, VOD, hybrid fiber coaxial network (HFC) technology, and multimedia services have been widely used. In particular, the application of optical transmission technology overcomes a series of serious defects in coaxia...
