We have based our telecommunications systems on the following requisites in order to provide an overall service:

- Globalisation.
- Aimed at the overall set of information systems, in which the network is one more component.
- Based on user service-level commitments.
- Aimed at the function or operations, and not at the system itself. Focused on the operations involving management of incidents, costs and safety.

Infrastuctures

We can classify the infrastructure of our installations into two broad groups:

- Those which are aimed at processing data.
- Those that send out, receive and process signals.
