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.
