Patent ID: 6909725

Claim:
A method for providing network states for a home phone line network, comprising the steps of: (a) determining if a receive-detect-with-Private Communication Field (PCOM)=0 signal is asserted; (b) asserting a set-detected PCOM=0 signal if the receive-detect-with-PCOM=0 signal is asserted, wherein assertion of the set-detected-PCOM=0 signal asserts a detected signal with a PCOM field set to “0”; (c) determining if a receive-detect-with-PCOM=2 signal or a transmit-detect-with-PCOM=2 signal is asserted; (d) asserting a set-signaled signal if either the receive-detect-with-PCOM=2 signal or the transmit-detect-with-PCOM=2 signal is asserted, wherein assertion of the set-signaled signal asserts a signaled signal; (e) determining if a force-first-mode signal is asserted, or a combination of a force-second-mode signal not being asserted and either the detected signal or the signaled signal being asserted; (f) setting a network state to a first mode if the force-first-mode signal is asserted, or the combination of the force-second-mode signal not being asserted and either the detected signal or the signaled signal being asserted; and (g) setting a network state to a second mode if the network state is not the first mode.
