BULK INTERFERENCE GROUP RECOVERY IN FULL DUPLEX CATV ARCHITECTURES
Systems and methods in a full duplex transmission network that selectively perform periodic sounding tests to determine an optimal interference group arrangement of cable modems, and stores a redundant copy of the latest optimal interference group arrangement for recovery after a system reset/reboot.
1 . A processing system in a CATV network having a plurality of cable modems, the processing system comprising:
a processor that selectively performs periodic sounding tests of the cable modems and determines an optimal interference group arrangement based on the sounding tests;
a memory that stores a redundant copy of the optimal interference group arrangement; where
the processor is capable of retrieving and implementing the optimal interference group arrangement following at least one of a system reset and a system reboot.
2 . The processing system of claim 1 in a full duplex CATV architecture.
3 . The processing system of claim 1 where the periodic sounding tests are a selected one of a CW test and an OUDP test.
4 . A method implemented by a processor in a CATV network having a plurality of cable modems, the method comprising:
selectively initiating periodic sounding tests of the cable modems;
using the sounding tests to determine an optimal interference group arrangement;
storing a redundant copy of the optimal interference group arrangement; and
recovering the stored redundant copy of the optimal interference group arrangement following at least one of a system reset and a system reboot.
5 . The method of claim 4 where the CATV system operates in a full duplex mode.
6 . The method of claim 4 where the periodic sounding tests are a selected one of a CW test and an OUDP test.
