Usage guidelines
With line probing enabled, the system performs the line probing function to find the highest possible data
transmission rate during line activation.
With line probing disabled, the system chooses the highest data transmission rate from the data
transmission rates supported by both the CPE and CO. The amount of time available for activating the
SHDSL lines is reduced because the line rate adaptation process is skipped.
Examples
# Disable SHDSL line probing on interface EFM 2/4/0.
<Sysname> system-view
[Sysname] interface efm 2/4/0
[Sysname-EFM2/4/0] undo shdsl line-probing enable
shdsl mode
Use shdsl mode to set the operating mode for an EFM interface.
