DI-304/DI-304M ISDN Remote Router
RIP-1/RIP-2
Routing Information Protocol (RIP) Support: Used in most LAN-to-LAN applications. The RIP protocol exchanges routing information between routers.
DHCP Support (Dynamic Host Configuration Protocol)
DHCP (Dynamic Host Configuration Protocol) allows IP addresses to be automatically and dynamically assigned to hosts on your network.
Networking Compatibility
The DI-304/DI-304M is compatible with remote access products from other companies such as Ascend, Cisco, and 3Com. Additionally, Microsoft Windows 95, 98, 2000, and Windows NT remote access capability are all supported.
Firmware Upgrade (TFTP) Server
Using this server and the Firmware Upgrade Utility software, you may easily upgrade to the latest firmware whenever enhanced features are added.
Web (HTTP) Server
A Web browser is the most common tool used to surf the Internet. You may use Microsoft Internet Explorer or any Netscape browser to configure the Router. It’s as easy as surfing a Website.
Virtual TA Server (VTA)
The terminology Virtual TA means the DI-304/DI-304M can operate as traditional ISDN TA to transmit and receive data, FAX, and voice transmissions via third-party software running on a desktop computer. In fact, a virtual TA server works as a network TA to exchange packets between an ISDN BRI and an Ethernet LAN. Therefore, desktop computers can use the ISDN line resource via an Ethernet LAN. In short, multiple users can share a network TA for backward compatibility with traditional applications, such as BBS, file transfer, sending/receiving FAXs, etc.
Remote Access Server (RAS)
RAS provides remote dial-in access services for home workers, branch offices, or telecommuters. DI-304/DI-304M routers offer 10 dial-in user profiles, including an authentication mechanism through CHAP/PAP and Calling Line Identification (CLID), secure callback functions, and 16 Lan-to-Lan Dialer Profiles.
Domain Name Server (DNS) Proxy
The DNS proxy maintains a DNS cache, including a mapping table between domain names and IP addresses. The proxy also remembers DNS query packets sent through the router and saves them into its own DNS cache. For enhanced speed, when a DNS query packet enters the router, the proxy searches its local DNS cache.
