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.

data packets are monitored and filtered. You can also configure your new router to block
