1.2 Features

Express Internet Access – ADSL2/2+ capable

The BiPAC 7300GX 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)

Communication Diversity with HSDPA/UMTS

Including one PC card slot, the BiPAC 7300GX router allows the users to insert a

3G/HSDPA PC card to share 3G/HSDPA, UMTS, EDGE, GPRS, or GSM Internet

connection.

802.11g Wireless AP with WPA Support

With integrated 802.11g Wireless Access Point in the router, the device offers a quick and

easy access among wired network, wireless network and broadband connection (ADSL)

with single device simplicity, and as a result, mobility to the users. In addition to 54 Mbps

802.11g data rate, it also interoperates backward with existing 802.11b equipment. The

Wireless Protected Access (WPA) and Wireless Encryption Protocol (WEP) supported

features enhance the security level of data protection and access control via Wireless LAN.

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 detection 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) to establish a

connection with an ISP. The router also supports VC-based and LLC-based multiplexing.

6

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

.

PPP over Ethernet (PPPoE)

The BiPAC 7300GX 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.

7

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 Internal IP address, External 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

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.

Web-based GUI

A web-based GUI offers easy configuration and management. 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.

Product Overview

Standards-Based Technology

The BiPAC 7300GX Wireless Router utilizes the

802.11g

standard. The IEEE

802.11g

standard is an extension of the 802.11b standard. It increases the data rate up to 54Mbps*

within the 2.4GHz band, utilizing

OFDM technology.

This means that in most environments,

within the specified range of this device, you will be able to transfer large files quickly or

even watch a movie in MPEG format over your network without noticeable delays. This

technology works by transmitting high-speed digital data over a radio wave utilizing

OFDM

(

O

rthogonal

F

requency

D

ivision

M

ultiplexing) technology.

OFDM

works by splitting the

radio signal into multiple smaller sub-signals that are then transmitted simultaneously at

different frequencies to the receiver.

OFDM

reduces the amount of

crosstalk

(interference)

in signal transmissions.

The BiPAC 7300GX is backwards compatible with 802.11b devices. This means that if you

have an existing 802.11b network, the devices in that network will be compatible with

802.11g devices at speeds of up to 11Mbps in the 2.4GHz range.

Installation Considerations

The BiPAC 7300GX Wireless Router lets you access your network, using a wireless

connection, from virtually anywhere within its operating range. Keep in mind, however, that

the number, thickness and location of walls, ceilings, or other objects that the wireless

signals must pass

Keep the number of walls and ceilings between the BiPAC 7300GX and other network

devices to a minimum - each wall or ceiling can reduce your BiPAC 7300GX wireless

product’s range from 3-90 feet (1-30 meters.)

Position your devices so that the number of walls or ceilings is minimized. Be aware of the

direct line between network devices.

Position the devices so that the signal will travel

straight through a wall or ceiling (instead of at an angle) for better reception. Building

Materials can impede the wireless signal - a solid metal door or aluminum studs may have

a negative effect on range.

Try to position wireless devices and computers with wireless adapters so that the signal

passes through drywall or open doorways and not other materials. Keep your product away
