Abstract

A error detection/correction system includes a plurality of cable modems for error detection/correction, a CMTS connected with the cable modems for access of MAC addresses of the cable modems and for controlling allocation of data flow of the cable modems, and a sample comparison system having a database of comparable data and connected with the CMTS for access of the data flow of the cable modems and then for comparison between the data flow and the comparable data to verify whether each of the cable modems functions well or not.

Claims

1. An error detection/correction system for cable modems, comprising:

a plurality of cable modems for detection;

a cable modem termination system (CMTS) connected with said cable modems for access of an MAC address of each of said cable modems and controlling allocation of data flow from said cable modems;

a sample comparison system having a database of comparable data, said sample comparison system being connected with said CMTS for access of data from said cable modems and for comparison between the data of said cable modems and the comparable data of said database to verify each of said cable modems functions well or not.

2. The error detection/correction system as defined in claim 1, wherein said sample comparison system comprises a computer, a dynamic host configuration protocol (DHCP) server, a trivial file transfer protocol (TFTP) server, and a hub connected with said CMTS, said computer, said DHCP server, and said TFTP server being connected respectively to said hub.

3. The error detection/correction system as defined in claim 2, wherein said database is installed in said computer, said computer being installed with an operating interface for manual operation, and a simple network management protocol (SNMP) servo program.

4. The error detection/correction system as defined in claim 1, wherein each of said cable modems is connected through a coaxial cable.
