Value log Type Event type
Possible values include:
– Cyclic value: a value is recorded every three minutes
– Event: only recorded when an event occurs
Time based on PC
clock
Date and time of the event
Port A/B
Data rate
Speed of the SHDSL connection
The lower the data rate, the greater the distance of the DSL
line.
Port A/B
Link losses
Number of connection losses since the last boot
Port A/B
SNR
The signal-to-noise ratio (SNR) is the ratio between the aver-
age useful signal strength and the average noise strength of
the interference signal. The greater the signal-to-noise ratio,
the higher the transmission quality.
The signal-to-noise ratio mainly depends on the cable attenu-
ation and the interference signals that influence the cable
(e.g., from adjacent cables).
Port A/B
Line attenuation
Reduction of the signal during transmission in dB. The lower
the line attenuation, the higher the transmission quality.
The line attenuation mainly depends on the cable length, the
cable cross section, and the data rate.
Port A/B/Ethernet port
RX network load
Network load for incoming data traffic
