ABSTRACT:
A system and method for performing Lifetest over a cable network system is provided which minimizes bandwidth usage by the Lifetest procedure while increasing the number of devices that the EMS may support. In accordance with the system and method, the EMS obtains device state information from the CMTS. Since the CMTS is constantly ranging its device population for state information, and since this information is stored in the DOCSIS Radio Frequency MIB, the EMS may obtain device state information by going to the MIB instead of directly to the device. This approach utilizes the distributed process inherently built into the system by taking advantage of the ranging that is already being performed by the CMTS. Since the EMS does not have to interact with every device in the system while performing Lifetest, consumption of bandwidth and processing resources is minimized.
