Router Features
The C54APRA2+ / C54APRB2+ ADSL Router utilizes the latest ADSL enhancements to provide a reliable Internet
portal suitable for most small to medium sized offices. The C54APRA2+ / C54APRB2+ advantages include:
• PPP (Point-to-Point Protocol) Security – The C54APRA2+ / C54APRB2+ Router supports PAP (Password
Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections.
• 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
network topology occur.
• Network Address Translation (NAT) – For small office environments, the C54APRA2+ / C54APRB2+ 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 (Transfer Control Protocol/Internet Protocol) – The C54APRA2+ / C54APRB2+ supports TCP/IP
protocol, the language used for the Internet. It is compatible with access servers manufactured by major vendors.
• RIP-1/RIP-2 – The C54APRA2+ / C54APRB2+ supports both RIP-1 and RIP-2 exchanges with other routers.
Using both versions lets 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”. 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 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 C54APRA2+ / C54APRB2+ 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.
• High Performance – Very high rates of data transfer are possible with the Router. Up to 8 Mbps downstream bit
rate using the G.dmt standard.
• Full Network Management – The C54APRA2+ / C54APRB2+ incorporates SNMP (Simple Network
Management Protocol) support for web-based management and text-based network management via an RS-232 or
Telnet connection.
• Telnet Connection – The Telnet enables a network manager to access the Router’s management software
remotely.
• Easy Installation – The C54APRA2+ / C54APRB2+ 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.
