Abstract
A cable network that includes a multi-slope equalizer and/or cable simulator.
Claims20
An equalizer for a cable network comprising:
- (a) said equalizer receiving an input signal having a frequency spectrum from an input coaxial cable;
- (b) said equalizer modifying said frequency spectrum of said input signal using a first signal conditioning shape for a legacy band extending from 300 MHz to 650 MHz, where said modification includes a greater attenuation at 300 MHz relative to 650 MHz;
- (c) said equalizer modifying said frequency spectrum of said input signal using a second signal conditioning shape for an extended band extending from 1.2 GHz to 1.5 GHz, where said first signal conditioning shape is different than said second conditioning shape;
- (d) said equalizer providing an output signal to an output coaxial cable for a customer.

A cable simulator for a cable network comprising:
- (a) said cable simulator receiving an input signal having a frequency spectrum from an input coaxial cable;
- (b) said cable simulator modifying said frequency spectrum of said input signal using a first signal conditioning shape for a legacy band extending from 300 MHz to 650 MHz, where said modification includes a lesser attenuation at 300 MHz relative to 650 MHz;
- (c) said cable simulator modifying said frequency spectrum of said input signal using a second signal conditioning shape for an extended band extending from 1.2 GHz to 1.5 GHz, where said first signal conditioning shape is different than said second conditioning shape;
- (d) said cable simulator providing an output signal to an output coaxial cable for a customer.

An equalizer for a cable network comprising:
- (a) said equalizer receiving an input signal having a frequency spectrum from an input coaxial cable;
- (b) said equalizer modifying said frequency spectrum of said input signal using a first signal conditioning shape for a legacy band of signaling within a first frequency range, where said modification includes a greater attenuation at a higher frequency than a lower frequency;
- (c) said equalizer modifying said frequency spectrum of said input signal using a second signal conditioning shape for an extended band of signaling within a second frequency range, where said first frequency range is lower than said second frequency range, where said first signal conditioning shape is different than said second conditioning shape;
- (d) said equalizer providing an output signal to an output coaxial cable for a customer.

A cable simulator for a cable network comprising:
- (a) said cable simulator receiving an input signal having a frequency spectrum from an input coaxial cable;
- (b) said cable simulator modifying said frequency spectrum of said input signal using a first signal conditioning shape for a legacy band of signaling within a first frequency range, where said modification includes a lesser attenuation at lower frequencies than at higher frequencies;
- (c) said cable simulator modifying said frequency spectrum of said input signal using a second signal conditioning shape for an extended band of signaling for a second frequency range, where said first frequency range is lower than said second frequency range, where said first signal conditioning shape is different than said second conditioning shape;
- (d) said cable simulator providing an output signal to an output coaxial cable for a customer.
