3.4.3 Value log
The value log can be printed or exported as a ".csv" file via the "Export" button.
Diagnostics >> Value log
Value log Type The type of event. Possible values include:
Cyclic value: a value is recorded every 3 minutes
Event: only recorded when an event occurs
Time based on PC
clock
Date and time of the event (based on the PC clock).
Port A/B
Data rate
The speed of the SHDSL connection. The lower the data rate,
the greater the distance of the DSL line.
Port A/B
Link losses
The 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
Error diagnostics
Indicates how strongly DSL data traffic is disturbed.
Port A/B
RX network load
Network load for incoming data traffic.
Port A/B
TX network load
Network load for outgoing data traffic.
Port A/B
Link quality
Quality of the data link.
Port A/B
Link status
The link status indicates the status of the connection.
D-SUB/COMBICON
status
Indicates the status of the serial connection via the D-SUB or
COMBICON interface of the device.
T-BUS
status
Indicates the status of the serial connection via the T-BUS DIN
rail connector.
