Lamp Test
Setting this value to a valid input
number provides a lamp test
facility (for use with a green wave
box). If the allocated input is
active (i.e. “1”) then all the OTU
output relays are energised.
Default: 255 – lamp test facility
disabled.

0-255
Assigns a bit position in the UTC
control word to indicate MOVA
fallback.
Condition '1' will enable MOVA to
send force bits to the traffic
controller in place of the UTC
control bits. Condition '0' will
select normal UTC operation i.e.
all the UTC control bits will be
sent to the traffic controller
Default value is 255 indicating
