Integrated ethernet over coaxial cable, STB, and physical layer test and monitoring

摘要

In a method of testing a residential broadband communication network, a residential gateway or set top box (STB) performs one or more single-ended parametric tests of the residential network that runs therebetween. The residential gateway or STB also performs one or more single-ended reflectometry tests of the residential network that runs therebetween. The residential gateway and the STB perform one or more dual-ended tests of the residential network that runs therebetween. The residential gateway dispatches the results of the foregoing tests to either: a device on the residential network, a device of another network that supplies broadband services to the residential network, or an intelligent device coupled to the residential gateway.

1. In a first, residential broadband communication network comprised of a first node and a second node, wherein the first node includes circuitry for application of AC and DC test signals in a direction on the first network toward the second node and a measurement circuit for detecting for the presence of AC and DC signals on the first network, and the second node includes circuitry for application of AC and DC test signals in a direction on the first network toward the first node and a measurement circuit for detecting for the presence of AC and DC signals on the first network, a method of testing the first network comprising:
(a) the first node or the second node performing one or more single-ended parametric tests of the first network that runs between the first node and the second node; (b) the first node or the second node performing one or more single-ended reflectometry tests of the first network that runs between the first node and the second node; (c) the first node and the second node performing one or more dual-ended tests of the first network that runs between the first node and the second node; and (d) the first node dispatching the results of the tests in steps (a)-(c) to either: a device on the first network, a device of a second network that supplies broadband services to the first network, or an intelligent device coupled to the first node.
