Abstract
A digital-channel-monitoring unit (DCMU) suitable for use in a coaxial-broadband network. The DCMU monitors quality, and integrity of digital and analog Radio Frequency (RF) channels from one or more remote locations in the network. These remote locations include one or more strategic locations between the headend, and a subscriber's premises, such as a business or home.
Claims20
A system for monitoring signal quality in a coaxial-broadband network, comprising:
- a slave modem, operable in an unregistered mode in the network, in which the slave modem records a plurality of operational characteristics of downstream channels in the network without having to register as a cable modem in the network;
- and
- a master modem, operable in a registered mode in the network, in which the master modem registers with a head-end system thereby providing a communication interface between the slave modem and the head-end system.
A method for monitoring signal quality in a coaxial-broadband network, comprising:
- using an unregistered modem in the network to record a plurality of operational characteristics of a downstream channel in the network;
- transferring the plurality of operational characteristics to a registered modem in the network;
- and transferring the plurality of operational characteristics from the registered modem in the network to a head-end system.
A method for displaying a graphical-user interface, comprising:
- receiving a plurality of recorded-operational characteristics about a monitored-downstream channel in a coaxial-broadband network;
- generating a first web-based page in response to user activity performed on a client device, the first web-based page containing details about the monitored-downstream channel including minimum and maximum power levels recorded over time;
- and
- generating a second web-based page in response to user activity performed on a client device, the second web-based page containing details about the monitored-downstream channel including at least one of:
- a bit error rate and a modulation error rate.
