The echo canceller is equipped with a tone disabler that responds to a disabling signal and causes the echo cancellation function to be disabled.. This attribute is characteristic of ECE. It falls in the TMN Configuration Category. It is a Read/Write attribute that has Enumerated Option values of None - The tone disabler function is not set. G.164 - The tone disabler function conforms to the echo suppressor tone disabler requirement detailed in Section 5 of ITU-T Recommendation G.164 dealing with the dectection of 2100 Hz tone with or withou phase reversal. G.165/G.168 - The tone disabler function conforms to the echo canceller tone disabler requirements detailed in Section 4 of ITU-T Recommendations G.165/G.168 dealing with the detection of of 2100 Hz tone with phase reversal. Switch 56 - Modified G.168 echo canceller tone disabler function dealing with the detection of a combination of 2100 Hz tone and the state of bit 8. The default value is: Comment: The data tone (2100 Hz) is defined in V.25,V.8. The behavior of the echo canceller in G164, G.165, G.168. Reference:
