LED ADSL/ADSL2+

The two-tone "ADSL/ADSL2+" LED (green/orange) indicates the status of
ADSL connection setup with the DSL access multiplexer in the exchange
as long as the flip switch is in the "On / ADSL Test" position.
The following displays are possible:
LED ADSL/ADSL2+ not lit up:
The VIT-A2 DSL Tester is switched off (the flip switch is in the "Off / Line
Test" position).
LED ADSL/ADSL2+ flashing slowly:
The tester is in ready mode and is sending stimuli to set up a connection
with the far end (DSLAM). As soon as a response to the activation is
received, the connection setup procedure moves to the next phase. The
LED indicates this by flashing faster (see below).
LED ADSL/ADSL2+ flashing quickly:
ADSL connection setup with the DSLAM is underway, i.e. a handshake
procedure in compliance with ITU G.994.1 is taking place first, followed by
a synchronization and training phase in compliance with ITU G.992.1 (for
ADSL), G.992.3 (for ADSL2) or G.992.5 (for ADSL2+).
LED ADSL/ADSL2+ constantly lit:
Synchronization with the DSLAM has been successfully completed, i.e. the
ADSL or ADSL2+ connection (including the ATM layer) has been
established. If this status is maintained (i.e. no immediate
resynchronization or flashing of the LED occurs), the DSL test has passed.
