1. A method for adaptive adjustment of a communication system, the method comprising:
- monitoring impulse noise on a communication channel during communication service, wherein monitoring the impulse noise comprises;
monitoring data transfer errors occurring on the communication channel;
determining whether any of the data transfer errors are packetized errors; and
determining a number of corrected packetized errors and a number of uncorrected packetized errors; and
selectively adjusting impulse noise protection without interrupting the communication service by changing the impulse noise protection in a first manner if the number of uncorrected packetized errors is greater than an uncorrected packetized error threshold and changing the impulse noise protection in a second manner that differs from the first manner if the number of corrected packetized errors is less than a corrected packetized error threshold, wherein selectively adjusting the impulse noise protection comprises;
selectively increasing the impulse noise protection if there are uncorrected packetized errors during a relevant observation time that is less than a threshold time value;
selectively decreasing the impulse noise protection if there are no uncorrected packetized errors during the relevant observation time and if a number of corrected packetized errors is less than a threshold value during the relevant observation time; and
leaving the impulse noise protection unchanged if there are no uncorrected packetized errors during the relevant observation time and if the number of corrected packetized errors is greater than or equal to the threshold value during the relevant observation time.

8. A communication system, comprising:
-
a communication channel; a first modem coupled with the communication channel, the first modem being adapted to monitor impulse noise and continuous noise on the communication channel during communication service and determine a number of corrected packetized errors and a number of uncorrected packetized errors during monitoring; and a second modem coupled with the communication channel; wherein the first and second modems are adapted to cooperatively adjust impulse noise protection and continuous noise protection without interrupting the communication service by changing the impulse noise protection in a first manner if the number of uncorrected packetized errors is greater than an uncorrected packetized error threshold and changing the impulse noise protection in a second manner that differs from the first manner if the number of corrected packetized errors is less than a corrected packetized error threshold, wherein the first and second modems are adapted to cooperatively adjust the impulse noise protection and the continuous noise protection in a coordinated fashion to minimize redundancy, wherein the first and second modems are adapted to selectively increase the impulse noise protection if there are uncorrected packetized errors on the communication channel during a relevant observation time that is less than a threshold time value, to selectively decrease the impulse noise protection if there are no uncorrected packetized errors on the communication channel and if a number of corrected packetized errors is less than a threshold value, and to leave the impulse noise protection unchanged if there are no uncorrected packetized errors on the communication channel and if the number of corrected packetized errors is greater than or equal to the threshold value. - View Dependent Claims (9)
