Line concentrator with storage function

A line concentrator with a storage function, said line concentrator has an insertion end connected to a connecting port and a housing provided with a plurality of connecting ports, said insertion end and said housing together compose the main body of said line concentrator, said housing has therein:

• a serially connected line concentrating circuit integrating therein a line concentrating and distributing control loop, a serial connecting-line interface, a serially connecting line and said insertion end extending to the exterior of said housing, said serially connected line concentrating circuit also including said connecting ports similarly extending to the exterior of said housing;
• and
• a flash memory storage circuit integrating therein a serial connecting-line interface, a microprocessor, a flash memory control loop, a flash memory, a memory and a power stabilizing loop;
• in said line concentrator, said line concentrating and distributing control loop of said serially connected line concentrating circuit is connected to said serial connecting-line interface of said flash memory storage circuit, and is connected to said connecting ports, to thereby form integration of said serially connected line concentrating circuit with said flash memory storage circuit, and said line concentrator is adapted to affording expanding and connection for other peripheral implements by taking advantage of the provision of said connecting ports, and forms a personal disk for storing data by taking advantage of said memories in said flash memory storage circuit.
