DTT Transmitters and Gap Fillers

NASERTIC is responsible for the management, operation, and maintenance of the television broadcasting equipment, consisting mainly of transmitters and gap fillers in 63 Telecommunications Centres and 57 cable distribution networks. The objective is to provide DTT broadcasting services in Zone II of the Chartered Community of Navarre, for the national, regional, and local DTT multiplexes defined for Navarre in the National Technical Plan for DTT.

To accomplish this, NASERTIC carries out all activities related to the documentation and inventory of components, monitoring and supervision, request and incident management, administration and management of physical and logical resources, and preventive, corrective, and proactive maintenance. It also performs all configuration or upgrade tasks, capacity and availability management, including the preparation of proposals for evolution and improvement. 

The elements that form part of this infrastructure are grouped into:
