Societa Italiana per l’Esercizio delle Telecomunicazioni SpA, Stet, is embarking on a $2.3m emergency programme to bring the ramshackle Roman telephone system up to the standard of those in other major European cities: it wants to cut the waiting time for residential phones to two months from the present six-and-a-half months by 1991, and also aims to install computers in the Rome telephone network.
