Getting to Know the BIPAC-5100/5100W

802.11b is only supported for the BIPAC-5100W

This chapter describes the key features and applications of BIPAC-5100/5100W.

1.1 Introducing the BIPAC-5100/5100W

The BIPAC-5100/5100W integrates high-speed 10/100Mbps auto-negotiating LAN interface(s)

and a high-speed ADSL port into a single package. The BIPAC-5100/5100W is ideal for

high-speed Internet browsing and making LAN-to-LAN connections to remote networks. By

integrating DSL and NAT, the BIPAC-5100/5100W provides super-fast Internet access to

multiple users at minimum cost.

The BIPAC-5100/5100W 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 BIPAC-5100/5100W provides a wireless LAN connectivity allowing users to enjoy the

convenience and mobility of working anywhere within the coverage area.

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-5100/5100W

The following sections describe the features of the BIPAC-5100/5100W.

¾

Four-Port Switch

A combination of switch and router makes the BIPAC-5100/5100W a cost-effective and viable

network solution. You can connect up to four computers to the LAN ports on you

BIPAC-5100/5100W without the cost of a hub.

¾

High Speed Internet Access

The BIPAC-5100/5100W ADSL router can support downstream transmission rates of up to 8

Mbps and upstream transmission rates of 1 Mbps.

¾

IEEE 802.11b 11Mbps Wireless LAN

7

The 11 Mbps wireless LAN provides mobility and a fast network environment for small and

home offices. Computers with wireless LAN Ethernet adapters can connect to the local area

network without any wiring efforts and enjoy reliable high-speed connectivity.

¾

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-5100/5100W 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.

¾

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).

¾

Universal Plug and Play (UPnP)

Using the standard TCP/IP protocol, the BIPAC-5100/5100W and other UPnP enabled devices

can dynamically join a network, obtain an IP address and convey its capabilities to other

devices on the network.

¾

10/100M Auto-negotiation Ethernet/Fast Ethernet Interface

This auto-negotiation feature allows the BIPAC-5100/5100W to detect the speed of incoming

transmissions and adjust appropriately without manual intervention. It allows data transfer of

either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on the

Ethernet network.

¾

Dynamic DNS Support

With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address,

allowing the host to be more easily accessible from various locations on the Internet. You must

register for this service with a Dynamic DNS client.

¾

Multiple PVC (Permanent Virtual Circuits) Support

The BIPAC-5100/5100W supports up to 8 PVC’s.

¾

ADSL Standards

♦

Full-Rate (ANSI T1.413, Issue 2; G.dmt (G.992.1) with line rate support of up to 8

Mbps downstream and 1 Mbps upstream.

♦

G.lite (G.992.2) with line rate support of up to 1.5Mbps downstream and 512Kbps

upstream.

♦

Supports Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (G.992.1); G.994.1

and G.996.1 (for ISDN only); G.991.1;G.lite (G992.2)).

♦

Supports OAM F4/F5 loop-back, AIS and RDI OAM cells.

♦

ATM Forum UNI 3.1/4.0 PVC.

8

♦

Supports up to 8 PVCs (UBR, CBR, VBR).

♦

Multiple Protocols over AAL5 (RFC 1483).

♦

PPP over AAL5 (RFC 2364).

♦

PPP over Ethernet (RFC 2516).

¾

DHCP Support

DHCP (Dynamic Host Configuration Protocol) allows individual clients (computers) to obtain

TCP/IP configuration at start-up from a centralized DHCP server. The BIPAC-5100/5100W has

built-in DHCP server capability enabled by default. It can assign IP addresses, an IP default

gateway and DNS servers to DHCP clients. The BIPAC-5100/5100W can now also act as a

surrogate DHCP server (DHCP Relay) where it relays IP address assignment from the actual

real DHCP server to the clients.

¾

IP Alias

IP Alias allows you to partition a physical network into logical networks over the same Ethernet

interface. The BIPAC-5100/5100W supports three logical LAN interfaces via its single physical

Ethernet interface with the BIPAC-5100/5100W itself as the gateway for each LAN network.

¾

IP Policy Routing (IPPR)

Traditionally, routing is based on the destination address only and the router takes the shortest

path to forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the

default routing behavior and alter the packet forwarding based on the policy defined by the

network administrator.

1.3 Applications for the BIPAC-5100/5100W

The BIPAC-5100/5100W is the ideal high-speed Internet access solution. The

BIPAC-5100/5100W supports the TCP/IP protocol, which the Internet uses exclusively. It is

compatible with all major ADSL DSLAM (Digital Subscriber Line Access Multiplexer) providers.

A DSLAM is a rack of ADSL line cards with data multiplexed into a backbone network

interface/connection (for example, T1, OC3, DS3, ATM or Frame Relay). Think of it as the

equivalent of a modem rack for ADSL. In addition, for BIPAC-5100/5100W, you can insert an

optional wireless PCMICA card into the BIPAC-5100/5100W and allow wireless stations

access to your network resources. A typical Internet access application is shown below.
