Getting to Know the BIPAC 5100S
This chapter describes the key features and applications of BIPAC 5100S.
1.1 Introducing the BIPAC 5100S
The BIPAC 5100S integrates high-speed 10/100Mbps auto-negotiating LAN interface and a
high-speed ADSL port into a single package. The BIPAC 5100S is ideal for high-speed Internet
browsing and making LAN-to-LAN connections to remote networks. By integrating DSL and
NAT, the BIPAC 5100S provides super-fast Internet access to multiple users at minimum cost.
The BIPAC 5100S is a bridge/router and includes two models, one for ADSL over POTS (Plain
Old Telephone System) and one for ADSL over ISDN (Integrated Synchronous Digital
System).
The web browser-based Graphical User Interface provides easy management and is totally
independent of the operating system platform you use.
1.2 Features of the BIPAC 5100S
The following sections describe the features of the BIPAC 5100S.

High Speed Internet Access
The BIPAC 5100S ADSL router can support downstream transmission rates of up to 8 Mbps
and upstream transmission rates of 1 Mbps.

PPPoE Support (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your
ISP to use their existing network configuration with newer broadband technologies such as
ADSL. The PPPoE driver on the BIPAC 5100S is transparent to the computers on the LAN,
which see only Ethernet and are not aware of PPPoE thus saving you from having to manage
PPPoE clients on individual computers.

Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address used
within one network (for example a private IP address used in a local network) to a different IP
address known within another network (for example a public IP address used on the Internet).
