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.
Product Application
Ethernet Distance extension
The GRT-402 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 4.6Mbps (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 for Enterprise and SME users or SOHO users who need high-speed symmetrical Internet connections. By utilizing the existing telephony infrastructure, network installation is simple and straightforward. With up to 4.6Mbps full duplex speed IP telephony, website hosting and various broadband services can be easily provisioned.
Key Features
Easy configuration and management with password control for various application environments
Efficient IP routing and transparent learning bridge to support broadband Internet services
NAT/PAT feature lets user both conserve valuable IP address space and reduce IP address management, meanwhile, also protects certain attack from outer network or internal workstations.
Fully ATM protocol stack implementation over SHDSL
PPPoA and PPPoE support user authentication with PAP/CHAP/MS-CHAP
SNMP management with SNMPv1/SNMPv2 agent and MIB II
Console and remote (Telnet or HTTP) administration allow user or service providers to locally or remotely diagnose network problems in detail
