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.
