Status
Line Status: Shows the current status of the ADSL line connection.
Link Type: Two types of link: Fast path and Interleaved path.
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 STR: Fast Path Header Error Concealment (HEC) errors.
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.
