D-Link DSL-520B Features
- PPP (Point-to-Point Protocol) Security – The DSL-520B ADSL Router supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections. The Router also supports MSCHAP.
- DHCP Support – Dynamic Host Configuration Protocol automatically and dynamically assigns all LAN IP settings to each host on your network. This eliminates the need to reconfigure every host whenever changes in the network topology occur.
- Network Address Translation (NAT) – For small office environments, the DSL-520B allows multiple users on the LAN to access the Internet concurrently through a single Internet account. This provides Internet access to everyone in the office for the price of a single user. NAT improves network security in effect by hiding the private network behind one global and visible IP address. NAT address mapping can also be used to link two IP domains via a LAN-to-LAN connection.
- TCP/IP (Transmission Control Protocol/Internet Protocol) – The DSL-520B supports the TCP/IP protocol, the language used for the Internet. It is compatible with access servers manufactured by major vendors.
- RIP-1/RIP-2 – The DSL-520B supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions allows the Router to communicate with all RIP enabled devices.
- Static Routing – This allows you to select a data path to a particular network destination that will remain in the routing table and never “age out”. Create a static route if you wish to define a specific route that will always be used for data traffic from your LAN to a specific destination within your LAN (for example to another router or a server) or to a specific destination outside your network (to an ISP defined default gateway for instance).
- Default Routing – This allows you to choose a default path for incoming data packets for which the destination address is unknown. This is particularly useful when/if the Router functions as the sole connection to the Internet.
- ATM (Asynchronous Transfer Mode) – The DSL-520B supports Bridged Ethernet over ATM (RFC1483), IP over ATM (RFC1577), and PPP over ATM (RFC 2364).
- Precise ATM Traffic Shaping – Traffic shaping is a method of controlling the flow rate of ATM data cells. This function helps to establish the Quality of Service for ATM data transfer.
- G.hs (Auto-handshake) – This allows the Router to automatically choose either the G.lite or G.dmt ADSL connection standards.
- High Performance – Very high rates of data transfer are possible with the Router. Up to 8 Mbps downstream bit rate is possible using the G.dmt standard.
- Telnet Connection – Telnet enables a network manager to access the Router’s management software remotely.
- Easy Installation – The DSL-520B uses a web-based graphical user interface program for convenient management access and easy set up. Any common web browser software can be used to manage the Router.
D-Link DSL-520B AFFORDABLE HIGH-SPEED CONNECTION FOR HOME & SMALL OFFICE
The D-Link DSL-520B ADSL2+ modem router is an affordable high-performance ADSL device for home and the small office. With integrated ADSL2/2+ supporting up to 24Mbps download speed, firewall protection, Quality of Service (QoS) and 4-port switch, this router provides all the essentials that a home or small office needs to establish a secure and high-speed remote link to the outside world.
FIREWALL PROTECTION & QoS
Security features prevents unauthorized access to the home and office network from Internet intruders. The router provides firewall security using Stateful. Packet Inspection (SPI) and Denial of Service (DoS) attack protection. SPI inspects the contents of all incoming packet headers before deciding what packets are allowed to pass through. Router access control is provided with packet filtering based on port and source/destination MAC/IP addresses. For Quality of Service (QoS), the router supports multiple priority queues to enable a group of home or office users to experience the benefit of smooth network connection of inbound and outbound data without concern of traffic congestion. This QoS support allows users to enjoy high ADSL transmission for applications such as VoIP, streaming multimedia and on-line games over the Internet.
