Communication parameter adjustment system in an internet compatible bi-directional communication system
First Claim
1. In a modem device for bi-directionally communicating with a remote head-end disposed in a location remote from the modem device, a method for providing warning of impaired communication, comprising the steps of:
- retrieving a communication parameter value from memory;
comparing said retrieved communication parameter value with a predetermined threshold to identify an excessive communication parameter value indicative of a potential communication link impairment; and
initiating substantially periodic transmission of a message from said modem device to said remote head-end indicating a non-modem-device-based system adjustment is necessary, in response to said comparison.

Abstract
A bi-directional communication system advantageously automatically senses and reports problems to a central operator network management station and operates with fewer subscriber service interruptions by detecting and correcting such conditions before they result in subscriber service interruption. Specifically, a system adaptively varies upstream transmission power level to prevent communication interruption in a cable modem network. A method for adaptively adjusting communication operation by varying a transmission parameter involves retrieving a communication parameter from memory and comparing the retrieved parameter with a predetermined threshold. A message is transmitted to a CATV head-end at a remote site representing that the parameter value indicates adjustment of the parameter is necessary.

30. A modem comprising:
-
means for retrieving a transmission power level value from memory; means for comparing said retrieved transmission power level value with a predetermined threshold to identify a transmission power level value indicative of a potential communication link impairment; and
means for launching a message, said message indicating that a non-modem-based system adjustment is necessary, from the modem to a remote head-end disposed in a location remote from the modem should said retrieved transmission power level value be at a value indicative of a potential communication link impairment.
