Abstract
The present invention establishes a communications link between a central office (CO) modem and a customer premise equipment (CPE) modem. The CO modem then evaluates the performance of the communications link. Impairments on the communications link are identified based on the evaluation results. Next, adjustment parameters for improving the performance of the communications link are determined. The CPE modem is then modified in accordance with the determined adjustment parameters to establish an adjusted communications link between the CO modem and the CPE modem. In this way, impairments such as bridged taps and cross-talk can be avoided.
Claims12
A method for improving communications performance between high speed communications devices, comprising the steps of:
- (a) establishing a communications link between a central office (CO) modem and a customer premise equipment (CPE) modem;
- (b) evaluating the performance of said communications link;
- (c) identifying impairments on said communications link;
- (d) determining adjustment parameters to improve the performance of said communications link;
- (e) modifying said CPE modem in accordance with said determined adjustment parameters to establish an adjusted communications link between said CO modem and said CPE modem.
A method for improving communications performance between high speed communications devices, comprising the steps of:
- (a) establishing a communications link between a central office (CO) modem and a customer premise equipment (CPE) modem, wherein said communications link uses a default upstream carrier frequency;
- (b) evaluating the performance of said communications link;
- (c) identifying one or more impairments on said communications link;
- (d) determining an adjusted upstream carrier frequency that reduces said identified impairments;
- (e) establishing an adjusted communications link between said CO modem and said CPE modem, wherein said adjusted communications link uses said adjusted upstream carrier frequency.
A method for improving communications performance between high speed communications devices, comprising the steps of:
- (a) establishing a communications link between a central office (CO) modem and a customer premise equipment (CPE) modem;
- (b) evaluating the performance of said communications link at a plurality of upstream carrier frequencies;
- (c) determining an adjusted upstream carrier frequency;
- (d) establishing an adjusted communications link between said CO modem and said CPE modem, wherein said adjusted communications link uses said adjusted upstream carrier frequency.
A system for improving communications performance between high speed communications devices, comprising:
- a central office (CO) modem;
- and
- a customer premise equipment (CPE) modem in communications with said CO modem over a communications link, wherein said CO modem is configured to determine adjustment parameters to improve the performance of said communications link.
