With broadband connectivity and home networking emerging as hot technologies, the residential gateway market is all set to explode. Apart from high-speed internet access, inexpensive packet telephony access from the realms of the home becomes appealing. A variety of other applications are bound to spring up around the residential gateway platform.

eGate is a reference design kit for developing residential gateway products. With a choice of broadband interfaces, home networking interfaces, and support for data and voice access from the home, eGate™ can be customized quickly for a variety of applications.

Included in the design kit is a hardware reference design for rapid product development. The highlight here is the eGate software consisting of several protocol stacks, drivers and applications, is structured to be highly modular and portable, enabling rapid product development based on other hardware platforms and real-time operating systems.
