7.2.1 VDSL Port Status Change
The VDSL port status change is shown as the following flow chart. Only when the status is
"Showtime", the VDSL connection is up.
Note: It’s suggested to perform the Dual-End-Loop-Test (DELT) when there is bad line
quality even though the VDSL connection is up. It brings the connection down right
away and takes several minutes to complete the whole test before re-negotiating
the connection.
