Loss of Frame Defect Shows the current status of the ADSL line.
Actual and maximum upstream data rate.
Actual and maximum downstream data rate.
Minimum noise margin upstream.
Minimum noise margin downstream.
Maximum fluctuation in the output power.
Maximum reduction in the strength of the upstream signal.
Maximum reduction in the strength of the 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.
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.
