The following table describes the information displayed after you type a loop command.
Information Description
Current Transmit Rate The rate at which data is transmitting.
Current Output Power The actual transmit power in dBm.
SNR Margin (1/10 dB) The signal-to-noise ratio of the signal received by the ATU, in
1/10 dB.
Line Attentuation (1/10 dB) The measured difference between the total power transmitted by
the sending ATU and the total power received by the receiving
ATU, in 1/10 dB.
Interleave Delay (ms) The number of milliseconds delay that is occurring between
interleaved data bits.
Errored Seconds The number of seconds in a 15-minute data collection period
during which errors occur that prevent the payload from being
corrected.
Loss of Frame The number of seconds in a 15-minute data collection period
during which the frames on the ADSL interface lose sync.
Loss of Signal The number of seconds in a 15-minute data collection period
during which the signal falls below the configured target noise
margin.
Current State The current status of the ADSL loop. Options:
•noDefect—There are no errors on the line.
•lossOfFraming—The line is not receiving valid frames.
•lossOfSignal—The line is not receiving valid signal.
•lossOfPower—The line is not receiving power.
•lossOfSignalQuality—The margin has fallen below the
configured target margin or the BER exceeds 10-7.
•dataInitFailure—The ATU was unable to initialize.
•configInitFailure—The ATU was unable to initialize because
the ATU at the other end does not support the requested
configuration.
•protocolInitFailure—The ATU was unable to initialize becau se
of an incompatible protocol used by the peer at the other end.
•noPeerAtuPresent—The ATU was unable to initialize because
no activation sequence was detected from the ATU at the other
end.
