Embodiment Construction

[0030] In order to better understand the present invention, the content of the present invention is further illustrated below in conjunction with the examples, but the content of the present invention is not limited to the following examples. Those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms are also within the scope of the claims listed in this application.

[0031] Such as figure 1 Shown is a block diagram of the integration method of the embedded ONU and EOC of the present invention. The upper part of the attached drawing is the connection block diagram of the ONU module, and the lower part is the connection block diagram of the EOC module. Among them, ONU's CPU (S3C2440), SDRAM memory and Flash flash memory are shared. The embedded software inside a CPU chip manages two devices at the same time. The FE interface of the ONU is internally connected with the MAC / PHY in the EOC, which plays the role of di...

Abstract

The invention relates to an embedded ONU (Optical Network Unit) and EOC (Ethernet Over Cable) integrating method. The method is characterized in that an ONU module and an EOC module share a CPU (Central Processing Unit), an SDRAM (Synchronous Dynamic Random Access Memory) and a Flash memory; embedded software inside a CPU chip manages the ONU module and the EOC module simultaneously; and an FE (Fast Ethernet) interface of the ONU module is internally connected with an MAC / PHY (Media Access Layer / Physical Layer) chip in the EOC module to play a role in directly transmitting signals. Through adoption of the embedded ONU and EOC integrating method, two different modules are integrated together, one CPU is adopted for performing embedded control, and flows inside the two modules are managed in a centralized way, so that the hardware cost and the software cost are reduced; the size and energy consumption are reduced; and convenience is brought to installation and debugging.

Description

technical field [0001] The invention relates to communication technology, in particular to an integration method of an embedded ONU and an EOC, which is mainly used in the field of broadcasting and television. Background technique [0002] ONU and EOC are two modules in triple play data transmission, ONU (Optical Network Unit) is a passive optical network unit, it chooses to receive broadcast data sent by OLT, and provides data, IPTV (Interactive Internet TV), voice (using IAD, that is, Integrated Access Device) and other services. EOC (Ethernet OverCable) is an access technology based on the cable TV coaxial cable network using the Ethernet protocol. In the two-way network reform of the radio and television transmission network, EPON+EOC technology is a technology that the State Administration of Radio, Film and Television focuses on promoting, and has been vigorously promoted and applied in my country's radio and television networks. This technology must adopt ONU and EO...
