4-Wire G.SHDSL Bridge/Router
 
  • Overview
4-wire (4-port) G.SHDSL EFM Router Solution
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 (small office/home office) customers, while reducing deployment and operation costs from service providers. Using existing telephone lines, the GRT-402 concentrates on all traffic onto a single high-speed trunk for Internet activities or shares a corporate intranet. Through the simple-yet-powerful management user interface of the GRT-402, network administrators can complete a managed network deployment simply in seconds.
High-speed Symmetric Data Transmission
With bandwidth of up to 11.4Mbps, the GRT-402 outperforms both T1’s at 1.544Mbps and E1’s at 2.048 Mbps. By using a standard RJ45 or phone wire as a connection medium, the installation and equipment costs of the GRT-402 are dramatically less than that of T1, E1 and Frame Relay. Using integrated bridging and routing support, two GRT-402s can be connected as a LAN-to-LAN network connection at the distance up to 7.7km (4.8 miles) via regular phone wire.
Built-in PPPoE Feature
The GRT-402 built-in PPPoE feature enables both the users and the service providers to make use of the existing PPP/PAP/CHAP based authentication and accounting infrastructure. The built-in PPPoE feature saves time by eliminating the need to install software.
High-speed Internet Access
G.SHDSL is the best solution to quickly providing cost-effective, high-speed network service for enterprises 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 11.4Mbps full duplex speed IP telephony, website hosting and various broadband services can be easily provisioned.
  • Applications
Ethernet Distance Extension (LAN to LAN Connection)
The GRT-402 is excellent for Ethernet distance extension over existing telephone wires. With just one pair of AWG-26 copper wires, you can easily connect two Ethernet networks with a maximum 5.7Mbps (at maximum 2.4km/1.6miles) full duplex transfer rate. Low-rate application is possible up to the maximum distance of 7.7 km/4.8 miles.
ISP Solution
G.SHDSL is the best solution to quickly providing cost-effective, high speed network service to enterprises and SME users or SOHO users which need high-speed symmetrical Internet connection. By utilizing existing telephony infrastructure, the network installation is simple and straightforward. With up to 11.4Mbps full duplex speed IP telephony, website hosting and various broadband services can be easily provisioned.
  • Key Features
Internet Access Features
  • 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
  • Full ATM protocol stack implementation over SHDSL / SHDSL.bis
  • PPPoA and PPPoE support user authentication with PAP/CHAP/MS-CHAP
  • DMZ host/Multi-DMZ/Multi-NAT enables multiple workstations on the LAN to access the Internet for the cost of IP address

Advanced Internet Functions
  • Easy configuration and management with password control for various application environments
  • SNMP management with SNMPv1/SNMPv2 agent and MIB II
  • Console and remote (Telnet or HTTP) administration allow users or service providers to locally or remotely diagnose network problems in details
  • Symmetrical data rate from 384Kbps to 11.4Mbps
  • Virtual LANs (VLANs) offer significant benefit in terms of efficient use of bandwidth, flexibility, performance and security
  • VPN pass-through for safeguarded connections
