Abstract

Logical channels in a network are automatically be configured by using measured network parameters. The measured network parameters are determined in cooperation with the network elements without interruption of active communication services. The network parameters include upstream or downstream modulation error ratio (MER), upstream or downstream signal to noise ratio (SNR), upstream or downstream microreflections, upstream transmit level, downstream receive power level, cable modem type (DOCSIS 1.0,1.1,2.0), functional capabilities (e.g., VoIP, 256QAM, etc), network element location with in a cable plant (e.g., node location or amplifier cascade depth), network element manufacturer, or type of services provided by the network element (including telephony versus data). An interactive display is provided to an operator which enables analysis of communication parameters, including modulation profiles and channel performance.
