Research areas
Transmission technology and fiber optics
CSELT became internationally known at the end of 1960s thanks to a cooperation with the US-based company
Computer science
In 1971, CSELT built the "Gruppi Speciali",[3] a time-division processing computer for telephone call switching. It was the second electronic switching system in Europe, following Britain's 1968 Empress,[4] but it was very advanced in its design: e.g. in 1975 was introduced for the first time an architecture-independent[clarification needed] automatic bootstrap from ROM composed from semiconductors, pushing a single button (and not by a long hand procedure input as in the past) and with the storage of the machine state of the switch, in order to have a quick automatic reboot of the switch in case of failure.[5]
Image processing: the Shroud of Turin
In 1978, CSELT also gained notoriety due to its 3D images of the Shroud of Turin, supervised by Giovanni Tamburelli: those images, the highest-resolution ones available at that time, followed the first 3D images of the Shroud that had been provided by NASA earlier during the same year. Notably, that work made the native "3D structure" of the Shroud itself apparent for the first time. A second result from Tamburelli was the electronic removal from the image of what was term "blood" covering the man of the Shroud.[6]
Speech technologies
1975 saw the release of

The last years
Several researches were carried also on later years in the field of optics circuits, microprocessor, antennas and all the fields of telecommunication as member of international standard group, such as
In March 2001 CSELT was merged by incorporation in Telecom Italia Lab (TI Lab), a new
Awards and recognition
- In 1988, CSELT was awarded the Eurotelecom Prize by Juan Carlos I for being "one of the main architects of the Race program for advanced technologies for telecommunications in Europe".[15]
- CSELT won the Telework Award, the first prize of the European Telework Week 1998, because of the experimental demonstration of the usefulness of CSELT technologies for disabled users, such as quadriplegics or blind people, with the combination of different voice technologies (remarkable for their high quality).[16][17]
