# ADSL Status

The Status screen displays information on connection line status, data rate, operation data and defect indication, and statistics.

### 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.
- Interleaved Path HEC Error: Interleaved Path Header Error Concealment (HEC) 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.

- Received cells: Number of cells received.
- Transmitted cells: Number of cells transmitted.
