PLANET IAD-200 ADSL 2/2+ VoIP Router and IAD-200W 802.11g Wireless ADSL 2/2+ VoIP Router provide ISP or residential home users with the ideal solution to sharing a high-speed ADSL 2/2+ broadband Internet connection on a 54Mbps wireless network (IAD-200W) and a 10/100Mbps Fast Ethernet backbone, and also with the capability of making calls through Internet. They can support downstream transmission rate up to 24Mbps and upstream transmission rate up to 3.5Mbps. These products support PPPoA (RFC 2364 – PPP over ATM Adaptation Layer 5), RFC 1483 encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516), and IPoA (RFC1577) to establish a connection with ISP. Via the user-friendly management interface, the IAD-200/200W can be managed by workstations running standard web browsers. Furthermore, both of them provide DHCP server support, virtual server, DMZ support, VPN PPTP/IPSec pass-through, and URL filtering capability. The IAD-200/200W also serves as an Internet firewall to protect your network from being accessed by outside users. It not only provides the natural firewall function (Network Address Translation, NAT), but also provides rich firewall features to secure a user’s network. All incoming data packets are monitored and filtered. Besides, the FXS interface and SIP (RFC3261) protocol offer the capability of makinga call in a cost-effective way, either through Internet or local phone system.
