Parameter Description
Status
Line Status:
Shows the current status of the ADSL
line.
Data Rate:
Downstream:
Actual and maximum downstream
data rate.
Upstream:
Actual and maximum upstream data
rate.
Operation Data/Defect Indication:
Noise Margin Upstream:
Minimum noise margin
upstream
Downstream:
Minimum noise margin downstream
Output Power:
Maximum f luctuation 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
Fast Path FEC:
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 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 interleaved superframes
received Interleaved.
Transmitted Cells:
Number of interleaved super
frames transmitted Superframes Interleaved.
Received Number of fast super frames received.
Superframes Fast
Transmitted Number of fast super frames transmitted.
