5.4 VDSL Command
For VDSL local and remote connections to establish, local switch and remote modem
must adjust to a corresponding rate. However if the distance between VC-412 and the
remote VDSL modem is too far then connection may not establish with high stream rates.
Therefore the VC-412 VDSL Managerial Switch and the VDSL remote modem are factory
set to the lowest stream rate; 4 Mbps downstream and 1 Mbps upstream. Once
connection between the VC-412 and the remote modem is established the switch will try
to adjust the stream rate to the next higher speed mode. If the next new stream rate failed
then it will go back to speed level-A (LWD mode) and progressively adjust to the last
highest effective rate. It will take approximately 10 seconds for the VC-412 to recalibrate
to LWD mode. This is called auto-speed.
In some situations higher stream rate is reachable but line quality might be poor due to
environmental factors or/and bad line conditions. In such circumstances, administrators
will want to define the maximum steam rate to a more stable rate. For example, if you
want to define the maximum speed on port-5 to speed level-B (5 Mbps symmetric) then
you can issue LR 5-B in the ICD command interface. Doing so will preset port-5
maximum speed to level-B therefore it will establish connection from speed level-A and if
succeeded, it will progress to level-B and stays at that point if it is reachable.
You can also manually set the port speed for testing purposes. To experiment, you must
first manually set the remote modem to a desired speed and then set the speed on the
