Description
Shows the current status of the ADSL line connection.
Two types of link: Fast path and Interleaved path.
Maximum upstream data rate.
Maximum downstream data rate.
Maximum upstream and downstream noise margin.
Maximum reduction in the strength of the upstream and downstream signal.
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.
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.
The number of Fast Path Cyclic Redundancy Check errors.
The number of Interleaved Path Cyclic Redundancy Check errors.
Momentary signal discontinuities.
Fast Path Header Error Concealment errors.
Interleaved Path Header Error Concealment 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.)
Number of cells received.
Number of cells transmitted.
