Abstract

The system comprises the three phases high voltage power circuit, the high frequency wave trap coil, the integrated filter, the transformer station and the low voltage power circuitry. Also, the system includes the switching in devices of the power circuitry with the digital broad / narrow band network being shared as well as the information stations connected to the ATM transmission interface in towns and villages. The invention comprises the small type microwave relay devices for interconnection between villages. The switching in network system operates at ATM mode so as to provide the features of large capacity and high-speed rate. The digitized narrow band anti-interference technique and the band compression technique are adopted in the transmission equipment.

Description

technical field [0001] The present invention relates to an access network system, in particular, an access network system for transmitting wide and narrowband digital information simultaneously through power lines in villages, small and medium-sized towns, outer suburbs of large and medium cities, and communities. Background technique [0002] Power lines are used to transmit high-frequency information on the frequency spectrum that transmits electric energy, referred to as simultaneous interpretation. At present, a network with a transmission rate of more than 2.5Gb / s in the backbone network and a transmission rate of 1Mb / s in the access network is usually called a broadband network. The broadband information described below refers to digital high-definition television and digital television. The current methods of transmitting broadband and narrowband information include digital optical cables, electric cables, ground and satellite microwave relay lines, etc. The construc...
