Statistics:
: displays results associated with the DSL link (WAN connection) and IP packets and Ethernet frames from the PC
connected to the LAN side of the tester which is acting as a modem.
DSL link statistics (page #1)
Connection status:
Connected or Not connected
Up Rate (bps):
attained rate for Upstream displayed in bit/s
Down Rate (bps):
attained rate for Downstream displayed in bit/s
Up Margin (dB):
Upstream noise margin expressed in dB (amount of noise measured on all active sub-channels in the
upstream and relative to a noise level needed to maintain a BER of < 10EXP-7)
Down margin (dB):
Downstream noise margin expressed in dB (amount of noise measured on all active sub-channels in
the downstream relative to a noise level needed to maintain a BER of < 10EXP-7)
Trained Modulation:
Operational mode achieved during negotiation and showtime.
LOS errors
: Error rate based on any Loss of Signal or Loss of Synchronization condition since the start of the test.
Up Attenuation (dB):
Upstream attenuation expressed in dB. Difference in the power level transmitted at the near end
(modem) and received at the far end (DSLAM)
Down Attenuation (dB):
Downstream attenuation expressed in dB. Difference in the power level transmitted at the near
end (modem) and received at the far end (DSLAM)
