From that trip, using UNIVAC equipment and developing the necessary software to convert that private company solution into a public network, the RETD (Special Data Transmission Network) was born.
It was the first public and its first node entered service in November , at the Madrid "Velázquez" exchange. The CTNE was ahead of the rest of the European countries in the deployment of public data switching networks.
On July , , the world's first public packet switching network was inaugurated in the Velázquez central office in Madrid. In this act, the then Minister Buy Bulk SMS Service of the Interior, before pressing the button to put the system into operation, pronounced, not without a certain innocence, the following words, making history:
I don't know very well what this is, but if it is for the good of the Spanish people, it is inaugurated!
The network had two other centers in addition to the one in Madrid, in Barcelona and Bilbao, with duplicate computers in both centers that began their journey with services. It was a packet switched network. This asynchronous communication allowed better use of network resources, since they were only used during times when there was actually traffic. It was originally composed of two levels: access network and transport network .
In , a key event in data transmission occurred: the International Telecommunications Union (ITU) approved the recommendation to standardize the interface between a station and a packet-switched network, and the X. standard for public networks was published. , based on packet switching, in whose development, Telefónica played a leading role.
was the year in which the real deployment began, as well as the definitive and unstoppable push to date, of public packet switching networks. The development and deployment of X.-based networks occurred especially in the s. This technology was added to the RETD in
The TESYS system
By the mid-s, RETD equipment had been upgraded from the first UNIVACs , but by the mid-s network traffic had grown so much that it required the installation of specially designed hardware such as packet switches.
