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.
