8.1 The system is designed to avoid, as far as
possible, any irretrievable breakdown of equipment which would hinder
the functioning of the services normally provided.
8.2 The most important items of equipment and
power sources are duplicated and the facilities are provided with
emergency generating sets as well as with UPS units. A maintenance
team, on call 24 hours a day, stands ready to repair to the extent
possible any breakdowns which may occur.
8.3 If operations are jeopardized at either TARIFA
TRAFFIC or TANGIER TRAFFIC, then the other centre will try to provide
the service.
