3.1.5 Performance
The EoVDSL ports can be configured in two modes – Auto Mode and Manual Mode. In Auto Mode,
which is the default mode, the unit will step through the different speeds and automatically select
the best bit-rate based on current line conditions. In Manual Mode the user can select one of the
speed settings and the unit will only attempt to attain the set speed. If the line conditions degrade
(reducing the SNR) but the unit is able to maintain the link, an alarm will be triggered to notify the
user of the reduced SNR. If the line conditions degrade such that the unit is unable to maintain the
current link, the unit will restart the scan process if in Auto Mode or re-attempt to attain the set
speed if in Manual Mode.
