Status
The Status page displays
ADSL status information.
Parameter Description
Line Status Shows the current status of the ADSL line.
Data Rate:
Upstream
Actual and maximum upstream data rate.
Downstream Actual and maximum downstream data rate.
Operation Data/Defect Indication:
Noise Margin:
Upstream
Minimum noise margin upstream.
Downstream Minimum noise margin downstream. Maximum
fluctuation in the output power
Output Power Attenuation:
Upstream Maximum reduction in the strength of the
upstream signal.
Downstream Maximum reduction in the strength of the
downstream signal.
Fast Path FEC
Correction There are two latency paths that may be used: fast
and interleaved. For either path a forward error
correction (FEC) scheme is employed to ensure
higher data integrity. For maximum noise immunity,
an interleaver may be used to supplement FEC.
Interleaved
Path FEC
Correction An interleaver is basically a buffer used to
introduce a delay, allowing for additional error
correction techniques to handle noise Interleaving
slows the data flow and may not be optimal for
real-time signals such as video transmission.
Fast Path CRC
Error Indicates the number of Fast Path Cyclic
Redundancy Check errors.
Interleaved
Path CRC Error Indicates the number of Interleaved Path Cyclic
Redundancy Check errors.
Loss of Signal
Defect Momentary signal discontinuities.
Loss of Frame
Defect Failures due to loss of frames.
Loss of Power
Defect Failures due to loss of power.
Fast Path HEC
Error Fast Path Header Error Concealment errors.
Interleaved
Path HEC Error Interleaved Path Header Error Concealment errors.
