The Planet new SHDSL family member, GRT-501, is the G.SHDSL.bis router that complies with ITU-T G.991.2 standard and provides affordable, flexible, and efficient Internet access solution for SOHO and Small Medium Business environment. The GRT-501 supports business-class and multi-range from 192kbps to 5.7Mbps (2-wire) symmetric data rates and also can be connected as the LAN-to-LAN network connection in the distance up to 6.7km (4.2 miles) by using existing telephone copper wires.
The Planet GRT-501 is integrated with high-end Bridging / Routing capabilities, advanced functions of DMZ, Virtual Server, and VPN pass-through. Because the network environment grows rapidly, Virtual LAN has become more and more important feature in internetworking industry. The GRT-501 supports IEEE 802.1Q VLAN over ATM network.

With the built-in Simple Network Management Protocol (SNMP) and web-based management, the GRT-501 offers an easy-to-use platform-independent management and configuration facility. The GRT-501 also provides Command-Line Interface, it can be accessed via Telnet and the console port. The network administrators can manage the device by proper ways.

• High Speed Symmetric Data Transmission
The GRT-501 supports the latest G.SHDSL.bis technology and provides the higher
symmetric data rate up to 5.7 Mbps on 2 wires
• CO and CPE side Support
Provides the back-to-back connection
• IEEE 802.1Q VLAN Support
The GRT-501 supports the IEEE 802.1Q Tagged VLAN, and it offers significant
