Description
Shows the current status of the ADSL line connection.
Shows the type of link.
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.
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.
