With the growing importance of the Internet, the number of users who want to access the Internet by dialup connection is increasing rapidly. This increases the load on existing switches because the duration of a dialup connection is generally longer than that of a normal voice call, so that telecommunication carriers are forced to substantially increase the number of switches. As economical solutions to this situation, Hitachi provides to telecommunication carriers an IP (Internet protocol) gateway system developed based on the integrated switching system technologies that Hitachi has nurtured over the years and a rapidly evolving IP technology. The gateway system can not only accommodate dialup traffic economically but can also support an up-and-coming technology, voice over IP (VoIP), which converts voice signals into IP data.
