INTERNET DATA TRANSMISSION APPARATUS, TRANSMISSION LINE AND ETHERNET OVER COAXIAL-CABLE DEVICE

摘要

Disclosed are an Internet data transmission apparatus, a transmission line and an Ethernet Over Coaxial-cable (EOC) device, and the apparatus includes: a Serial Attached Small computer system interface (SAS) socket or a Serial Advanced Technology Attachment (SATA) socket, the SAS socket or SATA socket includes at least 19 pins, wherein 4 pins are used for transmitting Internet data signals, 3 pins are used for transmitting board-on signals of an EOC modem module, 6 pins are used for transmitting power supply signals, and 6 pins are used for Inter-Integrated Circuit (I2C) control signals. The apparatus, transmission line and EOC device can reduce the cost and volume of EOC devices, and realize the capacity expansion of the EOC devices.
