G.SHDSL Bridge Router with 4-port Switch



Based on Digital Subscriber Line (DSL) technology, PLANET's new DSL product, the GRT-401 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-401 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-401, networks administrators can complete a managed network deployment just in seconds.

With bandwidth of up to 2.304Mbps, the GRT-401 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-401s 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-401's.

Ethernet Distance extension 
The GRT-401 is excellent for Ethernet distance extension over existing telephone wires. With just one pair of AWG-26 copper wire, you can easily connect two Ethernet networks far away (maximum 6.7 kilometers/4.2 miles) with a maximum 2.3Mbps (at maximum 3.3km/2.1 miles) full duplex transfer rate.

ISP Solution 
G.SHDSL is the best solution to quickly provide cost-effective, high speed network service to Enterprise and SME users or SOHO users which need high-speed symmetrical Internet connections. By utilizing the existing telephony infrastructure, network installation is simple and straightforward. With up to 2.3Mbps full duplex speed IP telephony, website hosting and various broadband services can be easily provisioned.
