ISDN coding and decoding coal mine underground remote-distance communication device based on power line carrier wave

The utility model discloses an ISDN coding and decoding coal mine underground remote-distance communication device based on a power line carrier wave, which comprises a base station controller and a plurality of communication links with identical structures. Each communication link consists of a base station end ISDN coder-decoder and a base station controller end ISDN coder-decoder which are connected through a communication cable, wherein the base station end ISDN coder-decoder is communicated with a base station; the base station controller end ISDN coder-decoder is communicated with the base station controller; and n is an arbitrary natural number larger than 1. The ISDN coding and decoding underground remote-distance communication device has the advantages of convenient wiring, simple equipment installation, high reliability, strong anti-jamming capability, good transmission efficiency and low system cost.
