Internet Access via Baseband and Broadband ISDN Gateways

As the concept of digital super-highway being more widely perceived among the computer and communications professionals and users, one of the focuses of eflorts is to take the full advantage of new technologies, to provide users with mazimum Intemet connectivity. Among all, ISDN is one of today’s technology with the ability to transmit voice, data, and imaging simultaneously with declining communications costs. It is expected that the connectivity via baseband ISDN will be vital for home users and small to medium-size organizations, in order to match up the unprecedented amount of daily electronic information. And the broadband ISDN is believed to be the foundation of digital super-highway technology. The ISDN gateway project was motivated to design a gateway, utilizing the mature and widespreading Intemet technology, to provide ISDN users with the Internet connectivity and services. This paper describes the design, implementation of an ISDN to Internet gateway, using the TCP/IP protocol suite.
