In the 1990s, Russia began to increase capacity in urban and local networks. Technological digital stations came together after the draft EU SKT (Unified system of switching equipment). Russian telecom operators prefer to operate PaBX units from famous foreign companies and major suppliers of telecommunications equipment such as Alcatel, Ericsson, Lucent Technologies, Nortel Networks, Siemens and others. Nevertheless domestic developments continued.
By the end of the twentieth century, the development of telecommunications began to move confidently in the direction of the gradual merging of voice networks and data. IP-telephony entered the scene, spawning a new generation. Around the same time period (the end of the 20th to the beginning of the 21st Century.) the so-called pure IP - PaBX (Private Automatic Branch Exchange) began appearing. New opportunities 'Voice over Internet' has adversely affected the development of the payphone. The development of new terminals that combine the capabilities of traditional public telephone systems and computer have led to WEB-payphones. New devices have become embedded in the major cities of our country. With their help you can access the Internet, use e-mail, send SMS-messages, take pictures and send photos via e-mail. Payments are made using phone cards.
Soon, however, the number of users of such devices will have significantly decreased: the priority is now rapidly developing, multi-functional and affordable mobile communication. The cellular network in Russia was to be implemented from 1990. On September 9, 1991 the Delta Telecom Company launched our country's first first cellular network (operating in NMT-450 standard) in our northern capital. The then Mayor of St. Petersburg, Anatoly Sobchak, made the first significant call using cellular technology.
