Output Power: Maximum fluctuation in the output power.
Attenuation Upstream: Maximum reduction in the strength of the
upstream signal.
Attenuation Downstream: Maximum reduction in the strength of the
downstream signal.
There are two latency paths that may be used: fast and Correction
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 An interleaver is basically a buffer used to introduce a delay,
FEC Correction 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 indicates the number of Fast Path Cyclic Redundancy
Check Error errors. Interleaved Path indicates the number of
Interleaved Path Cyclic Redundancy Error Check errors.
Loss of Signal Momentary signal discontinuities. Defect Loss of Frame
Failures due to loss of frames.
Loss of Power Defect: Failures due to loss of power.
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.)
