Operating Mode
The operating mode offers multiple setting options and can be configured in RT (“remote
terminal” or CPE) or COT (“central office terminal”) mode.
EFM G.hs Mode
ITU G.hs according to ITU-T G.994.1 and IEEE802.3ah
PMMS Mode (Line Probing)
Line Probing according to ITU-T G.991.2 (2004)
PMMS Target Margin
Desired Signal Noise Ratio for the PMMS-mode

Loop Attenuation (dB)
Measured loop attenuation in dB; longer loop length results in high loop attenuation.
SNR (dB)
The SNR (“signal noise ratio”) is an index of the line quality. The larger the SNR the better is
the line quality. The SNR ranges from -10 dB to 21 dB.
3.9.3 Performance
This view shows actual performance values of all lines.
Time Stamp
Shows the time after activation of the NT function or the elapsed time (24h format) after acti-
vation of the SHDSL line.
