Cause Unit failure in the upstream node that generated the tributary unit pointer or in
the node that reported the alarm.
Actions Check on the management system if unit failure is reported for the unit
generating the tributary unit pointer.
In that node, remove the unit and replace it with a new one.
When unit failure is not reported, loop the STM-n signal at the transmitting
node and at the receiving node. In this condition, the node reporting TU-3 Loss
of pointer contains the faulty unit.
