Based on Digital Subscriber Line (DSL) technology, PLANET's new DSL product, the GRT-402 provides an affordable, flexible, and efficient Internet access solution for SOHO customers, while reducing deployment and operational costs from service providers. Using existing telephone lines, the GRT-402 concentrates all traffic onto a single high-speed trunk for Internet activities or sharing a corporate intranet. Through the simple-yet-powerful management user interface of the GRT-402, networks administrators can complete a managed network deployment just in seconds.

With bandwidth of up to 4.608Mbps, the GRT-402 outperforms both T1's at 1.544 Mbps and E1's at 2.048 Mbps. By using a standard RJ-11 phone wire as a connection medium, the installation and equipment cost of the GRT is dramatically less than that of T1, E1 or Frame Relay.Using integrated bridging and routing support, two GRT-402s can be connected as a LAN-to-LAN network connection at a distance up to 6.7km (4.2 miles) using regular phone wire, eliminating the need for expensive leased line CSU/DSU peripherals and V.35 Cisco routers. Now two offices can be connected for inter-LAN communication using just one telephone pair and two GRT-402's.

• Easy configuration and management with password control for various application
environments
• Efficient IP routing and transparent learning bridge to support broadband
Internet services
