System and method for calibrating power level during initial ranging of a network client device
First Claim
1. In a data-over-cable system, a method for establishing communications between a network client device and a network device;
- the method comprising;
a) dividing a dynamic range of the network client device into a plurality of regions by dividing the dynamic range of a transmitter of the network client device by the dynamic range of a receiver of the network device;
b) initiating at least one initial ranging in at least one of the regions using a certain power level;
c) determining if a range response message is received from the network device;
d) adjusting the power level and reinitiating step b) and c) till a range response message is received.

Abstract
A system and method for calibrating power level during initial ranging of a network client device, such as cable modem facilitates communications between a network client device and a network device such as a cable modem termination system. The method includes dividing the dynamic range of the cable modem transmitter into a plurality of regions and attempting initial ranging in each of the different regions. If a response is not received from the network device, the method including adjusting the power level and reattempting the initial ranging in the different regions. Once a range response message is received from the network device the process of initial ranging is complete.
