Parameter Description
Operation Mode
It allows to specify the ADSL standards to operate with. The following standards
below are supported :
¾ Automatic
¾ T1.413 Issue 2
¾ G.992.1 (G.DMT)
¾ G.992.2 (G.Lite)
¾ G.992.5 (ADSL 2+)
Status
Line Status Shows the current status of the ADSL line connection.
Link Type
Shows the current Link Type: Interleaved or Fast.
Data Rate
Upstream Maximum upstream data rate.
Downstream
Maximum downstream data rate.
Operation Data / Defect Indication
Noise Margin Maximum upstream and downstream noise margin.
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.
Fast Path HEC Error
Fast Path Header Error Concealment errors.
Interleaved Path HEC Error
Interleaved Path Header Error Concealment errors.
Statistics
