Introduction  
1.1 Introducing the BiPAC 7202(G)  
Thank you for purchasing the BiPAC 7202(G) ADSL Router by Billion. Your new router is an  
all-in-one unit that combines an ADSL modem, ADSL router and Ethernet network switch to  
provide everything you need to get the machines on your network connected to the Internet  
over an ADSL broadband connection.  
The BiPAC 7202(G) router complies with ADSL2+ standards for deployment worldwide and  
supports downstream rates of up to 24 Mbps and upstream rates of up to 1 Mbps. Designed  
for small office, home office and residential users, the router enables even faster Internet  
connections. You can enjoy ADSL services and broadband multimedia applications such as  
interactive gaming, video streaming and real-time audio much easier and faster than ever  
before.  
The BiPAC 7202(G) supports PPPoA (RFC 2364 – PPP (Point-to-Point Protocol) over ATM  
Adaptation Layer 5), RFC 1483 encapsulation over ATM (bridged or routed), PPP over  
Ethernet (RFC 2516), and IPoA (RFC1577) to establish a connection with your ISP. Your  
new router also supports VC-based and LLC-based multiplexing.  
The perfect solution for connecting a small group of PCs to a high-speed broadband Internet  
connection, the BiPAC 7202(G) allows multiple users to have high-speed Internet access  
simultaneously.  
Your new router also serves as an Internet firewall, protecting your network from access by  
outside users. Not only does it provide a natural firewall function with Network Address  
Translation (NAT), it also provides rich firewall features to secure your network. All incoming  
data packets are monitored and filtered. You can also configure your new router to block  
internal users from accessing the Internet.  
The BiPAC 7202(G) provides two levels of security support. First, it masks LAN IP  
1
 
 
addresses making them invisible to outside users on the Internet, so it is much more difficult  
for a hacker to target a machine on your network. Second, it can block and redirect certain  
ports to limit the services that outside users can access. To ensure that games and other  
Internet applications run properly, you can open specific ports for outside users to access  
internal services on your network.  
The Integrated DHCP (Dynamic Host Control Protocol) client and server services allow  
multiple users to get IP addresses automatically when the router boots up. Simply set local  
machines as a DHCP client to accept a dynamically assigned IP address from the DHCP  
server and reboot. Each time a local machine is powered up; the router recognizes it and  
assigns an IP address to instantly connect it to the LAN.  
For advanced users, Virtual Service (port forwarding) functions allow the product to provide  
limited visibility to local machines with specific services for outside users. You can set an  
ISP (Internet Service Provider) provided IP address on the BiPAC 7202(G) and then you can  
reroute specific services to individual computers on your local network. For instance, a  
dedicated web server can be connected to the Internet via the router and then incoming  
requests for web pages that are received by the router can be rerouted to your dedicated  
local web server, even though the server now has a different IP address.  
Virtual Server can also be used to re-task services to multiple servers. For instance, you can  
set the router to allow separated FTP, Web, and Multiplayer game servers to share the same  
Internet-visible IP address while still protecting the servers and LAN users from hackers.

1.2 Features  
Express Internet Access – ADSL2/2+ capable  
The BiPAC 7202(G) complies with ADSL worldwide standards. Supporting downstream  
rates of 8Mbps with ADSL, the router is capable of up to 12/24 Mbps with ADSL2/2+, and  
upstream rates of up to 1 Mbps. Users enjoy not only high-speed ADSL services but also  
broadband multimedia applications such as interactive gaming, video streaming and  
real-time audio which are easier and faster than ever. The router is compliant with  
Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (ITU G.992.1); G.hs (ITU G994.1);  
G.dmt.bis (ITU G.992.3); and G.dmt.bisplus (ITU G.992.5)  
Fast Ethernet Switch  
A 4-port 10/100Mbps fast Ethernet switch is built-in with automatic switching between MDI  
and MDI-X for 10Base-T and 100Base-TX ports, with auto dection allowing you to use either  
straight or cross-over Ethernet cables.  
Multi-Protocol to Establish a Connection  
The router supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483  
encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516) and IPoA  
(RFC1577) to establish a connection with an ISP. The router also supports VC-based and  
LLC-based multiplexing.  
Quick Installation Wizard  
A web-based GUI and quick installation wizard help you easily install the BiPAC 7202(G).  
Enter your ISP’s information and begin browsing the Internet immediately.  
Universal Plug and Play (UPnP) and UPnP NAT Traversal  
This protocol is used to enable simple and robust connectivity among stand-alone devices  
and PCs from many different vendors, and it makes setting up a network simple and  
affordable. UPnP architecture leverages TCP/IP and the Web to enable proximity  
networking in addition to control and data transfer among networked devices. With this  
feature enabled, you can seamlessly connect to Net Meeting or MSN Messenger.  
Network Address Translation  
Network Address Translation (NAT) allows multiple users to access outside resources such  
as the Internet simultaneously with one IP address/one Internet access account. Many  
application layer gateways (ALG) are supported such as web browser, ICQ, FTP, Telnet,  
E-mail, News, Net2phone, Ping, NetMeeting, IP phone and others.  
Firewall  
NAT technology supports simple firewalls and provides options for blocking access from the  
Internet, like Telnet, FTP, TFTP, WEB, SNMP and IGMP.

Domain Name System Relay  
Domain Name System (DNS) relay provides an easy way to map a domain name with a  
user-friendly name such as www.billion.com with an IP address. When a local machine sets  
its DNS server to the router’s IP address, every DNS conversion request packet from the PC  
to this router is forwarded to the real DNS on the outside network.  
Dynamic Domain Name System (DDNS)  
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname.  
This dynamic IP address is the WAN IP address. To use the service, you must first apply for  
an account from a DDNS service such as http://www.dyndns.org/.  
PPP over Ethernet (PPPoE)  
The BiPAC 7202(G) provides an embedded PPPoE client function to establish a connection.  
You get greater access speed without changing the operation concept, while sharing the  
same ISP account and paying for one access account. No PPPoE client software is required  
for the local computer. Automatic Reconnect and Disconnect Timeout (Idle Timer) functions  
are also provided.  
Quality of Service (QoS)  
QoS gives you full control over which types of outgoing data traffic should be given priority  
by the router, ensuring important data like gaming packets, customer information, or  
management information move through the router ay lightning speed, even under heavy  
load. The QoS features are configurable by source IP address, destination IP address,  
protocol, and port. You can throttle the speed at which different types of outgoing data pass  
through the router, to ensure P2P users don’t saturate upload bandwidth, or office browsing  
doesn’t bring client web serving to a halt. In addition, or alternatively, you can simply change  
the priority of different types of upload data and let the router sort out the actual speeds.  
Virtual Server:  
You can specify which services are visible to outside users. The router detects an incoming  
service request and forwards it to the specific local computer for handling. For example, you  
can assign a PC in a LAN to act as a Web server inside and expose it to the outside network.  
Outside users can browse inside the web server directly while it is protected by NAT. A DMZ  
host setting is also provided for local computers exposed to the outside Internet network.  
Dynamic Host Configuration Protocol (DHCP) Client and Server  
On a WAN site, the DHCP client obtains an IP address from the Internet Service Provider  
(ISP) automatically. On a LAN site, the DHCP server allocates a range of client IP  
addresses, including subnet masks and DNS IP addresses and distributes them to local  
computers. This provides an easy way to manage the local IP network.  
Rich Packet Filtering  
4
 
This feature filters the packet based on IP addresses as well as Port numbers. Filtering  
packets to and from the Internet provides a higher level of security control.  
Static and RIP1/2 Routing  
An easy static routing table or RIP1/2 routing protocol supports routing capability.  
Simple Network Management Protocol (SNMP)  
SNMP allows convenient remote management of the router.  
Web-based GUI  
A web-based GUI offers easy configuration and management. User-friendly and with on-line  
help, it also supports remote management capability for remote users to configure and  
manage this product.  
Firmware Upgradeable  
You can upgrade the router with the latest firmware through its web-based GUI.
