The abandonment of the four-digit numbering system that began with 19 caused some technological anxiety. In the end, nothing happened, and it all turned out to be a rather expensive scare.

This is a time of structural changes within the company. Maintenance services for the Distribution Networks are consolidated, and the Hydroelectric Power Plants operate independently. The era of fiber optic cable arrives. Thousands of kilometers are laid, mostly self-supporting OPGW cable. Demand for increased bandwidth necessitates abandoning PDH technology in favor of SDH. Data processing will be handled by equipment capable of comprehensively processing basic information to deliver 2 Mbps frames to the transmission equipment. These are known as Newbridges.

The Communications Control Center grows in importance, and symbolic language truly flourishes. Words and acronyms with Anglo-Saxon names are coined, encapsulating complex technological philosophies: Router, Bridge, Gateway, Ethernet, PCM, PSTN, ISDN, PDH, SDH, ATM, ADSL, Frame Relay, DECT, etc. Radiotelephony is integrated into the corporate network, enabling the miracle of communication between landline, mobile, and cordless phones, radio equipment, and computers. The unification of telecommunications at the national level becomes a reality, and what were once competing electric companies are now united under a single acronym: ENDESA. From this point on, it is no longer history, but the future, that must be recounted.
