Higher symmetric data rates power office productivity!
Small businesses often can maintain competitiveness by using a cost-effective networking solution instead of expensive leased 
lines for an online presence. As a substitute for a local leased line, Billion’s BiPAC 8501/8521 series offers a perfect solution with 
symmetric transmission so SOHO and SME users can enjoy high-speed SHDSL.bis broadband services. Users can also access 
bandwidth-consuming  applications  such  as  video  conferencing  with  greater  ease  and  speed  than  previously.  The  device 
supports the latest SHDSL.bis technology with a higher symmetric upstream and downstream data rate of up to 5.7Mbps or 
11.4Mbps. The Rate Adaptive feature allows the BiPAC 8501/8521 series to adjust the data rate automatically according to the 
quality of the wire connection. The Quality of Service feature ensures a smooth net connection for inbound and outbound data 
with  minimal  traffic  congestion.  The  BiPAC  8501  also  supports  IPSec  VPN  for  users  to  create  secure  data  communication 
between two or more sites. Rich Firewall security features such as SPI, DoS attack prevention and URL Content Filtering are 
also integrated, providing users with unparalleled access protection.
High-speed Internet Access with 2/4-wire SHDSL.bis
The BiPAC 8501/8521 series complies with the latest SHDSL.bis technology standards for worldwide deployment and supports 
a symmetric data rate of up to 5.7Mbps/11.4Mbps. With SHDSL.bis technology, the BiPAC 8501/8521 series allows office users 
to enjoy high-speed symmetric bandwidth and access multimedia applications such as FTP sharing, video conferencing and 
real-time audio with greater ease and speed than ever before.
Smooth, Responsive Net Connection
The Quality of Service (QoS) feature helps users to manage their bandwidth and prioritize data transfer effectively. It gives full 
control over the passage of any type of data, ensuring latency-sensitive and bandwidth-consuming applications such as video 
conferencing, customer information or FTP sharing, can move through the router at instantaneous speed, even when experiencing 
heavy use. The speed for inbound and outbound data passed through the router can be controlled to ensure that users do not 
saturate bandwidth with browsing activities.
Firewall Security with DoS Prevention and SPI
Besides having a built-in NAT natural firewall feature, the BiPAC 8501/8521 series also provides advanced hacker pattern-filtering 
protection that can automatically detect and block Denial of Service (DoS) attacks, such as IP Spoofing, Ping of Death, etc. The 
router is also built with Stateful Packet Inspection (SPI) to determine whether a data packet should be allowed to pass through 
the firewall to the private LAN.
Virtual Private Network
The BiPAC 8501 supports embedded Virtual Private Network (VPN) protocols for users to establish private encrypted tunnels 
over the public Internet.
