The following items are included on this information page:
Parameter Description
Status
Line Status Shows the current status of the ADSL line connection.
Data Rate
Upstream Maximum upstream data rate.
Downstream Maximum downstream data rate.
Operation Data/Defect Indication
Noise Margin Maximum upstream and downstream noise margin.
Output Power Maximum fluctuation in the output power.
Attenuation Maximum reduction in the strength of the upstream and 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
The number of Fast Path Cyclic Redundancy Check errors.
Interleaved Path CRC Error
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.
Statistics
Superframes represent the highest level of data presentation.
Each superframe contains regular ADSL frames, one of which is used to provide
superframe synchronization, identifying the start of a superframe. Some of the
remaining frames are also used for special functions.rs.
Received Superframes Interleaved
Number of interleaved superframes received.
Transmitted Superframes Interleaved
Number of interleaved superframes transmitted.
Received Superframes Fast
Number of fast superframes received
Transmitted Superframes Fast
Number of fast superframes transmitted.
