Abstract: Systems, apparatuses, and methods are described for deploying upstream bandwidth upgrade of devices per home basis. The impact of the upstream bandwidth upgrade on the devices may be pre-estimated based on remotely monitoring and/or analyzing performance data of the devices collected during transmissions of test signals (e.g., a burst of upstream transmissions) in real-time from the devices operating under different modes of operations. The burst of upstream transmissions using a small bandwidth (e.g., 1.6 MHz) may be limited to a short duration of time (e.g., 5 seconds) so that on-going services provided by the devices are not substantially interrupted. The upstream bandwidth of the devices, based on the pre-estimated impact, may be upgraded, left unaltered, or downgraded.

Abstract: A method and system for multi-port aggregation in a digital return path CATV system digitizes each of a plurality of return path signals, splits each of the plurality of return path signals into a low band and an upper band (41), combines each of the plurality of low band signals to form a combined low band signal (43), downconverts each of the plurality of upper band signals from an original frequency range into a new downconverted frequency range (45) and time division multiplexes the plurality of downconverted upper band signals with the combined low band signal to form an aggregate data stream (46).
