The following items are included on the ADSL status page:

 

 

 

 

 

 

 

Parameter

Description

 

 

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

An interleaver is basically a buffer used to introduce a delay, allowing for

 

 

Correction

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

(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.
