Introduction
1.1 Introducing the BEC 7300N
Thank you for purchasing the BEC 7300N Router. Your new router is an all-in-one unit that
combines an ADSL modem, ADSL2/2+ 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 BEC 7300N 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 enjoyADSL services and broadband multimedia applications such as
interactive gaming, video streaming and real-time audio much easier and faster than ever
before.
The BEC 7300N 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) 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 BEC 7300N allows multiple users to have high-speed Internet access
simultaneously.
Your new router also serves as an Internet firewall, protecting your network from access by
outside users. Not only does it provide a natural firewall function with Network Address
Translation (NAT), it also provides rich firewall features to secure your network.All incoming
data packets are monitored and filtered. You can also configure your new router to block
internal users from accessing the Internet.

5
The BEC 7300N provides two levels of security support. First, it masks LAN IP addresses
making them invisible to outside users on the Internet, so it is much more difficult for a
hacker to target a machine on your network. Second, it can block and redirect certain ports
to limit the services that outside users can access. To ensure that games and other Internet
applications run properly, you can open specific ports for outside users to access internal
services on your network.
The Integrated DHCP (Dynamic Host Control Protocol) client and server services allow
multiple users to get IP addresses automatically when the router boots up. Simply set local
machines as a DHCP client to accept a dynamically assigned IP address from the DHCP
server and reboot. Each time a local machine is powered up; the router recognizes it and
assigns an IP address to instantly connect it to the LAN.
For advanced users, Virtual Service (port mapping) functions allow the product to provide
limited visibility to local machines with specific services for outside users. For instance, a
dedicated web server can be connected to the Internet via the router and then incoming
requests for web pages that are received by the router can be rerouted to your dedicated
local web server, even though the server now has a different IP address.
Virtual Server can also be used to re-task services to multiple servers. For instance, you can
set the router to allow separated FTP,Web, and Multiplayer game servers to share the same
Internet-visible IP address while still protecting the servers and LAN users from hackers.

1.2 Features
Express Internet Access – ADSL2/2+ capable
The BEC 7300N complies with ADSLworldwide 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)
802.11n Wireless AP with WPA Support
With integrated 802.11n 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 300 Mbps
802.11n data rate, it also interoperates backward with existing 802.11g and 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.
EWAN
Besides using ADSL to get connected to the Internet, BEC 7300N offers its Ethernet port 1
as a WAN port to be used to connect to Cable Modems, VDSL and fibre optic lines. This
alternative, yet faster method to connect to the internet will provide users more flexibility to
get online.
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.

7
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.google.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 http://www.dyndns.org/.
PPP over Ethernet (PPPoE)
The BEC 7300N 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 oneaccess account. No PPPoE client software is required
for the local computer. Automatic Reconnect and Disconnect Timeout (Idle Timer) functions
are also provided.
Quality of Service (QoS)

8
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 simplychange
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 actas aWeb serverinside and expose itto the outside network.
Outside users can browse inside the web server directly while it is protected byNAT. 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 BEC 7300NWireless Router utilizes the 802.11n standard. The IEEE 802.11n standard
is an extension of the 802.11g standard. It increases the data rate up to 300 Mbps 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 (Orthogonal
Frequency Division Multiplexing) 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.
Installation Considerations
The BEC 7300NWireless 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 BEC 7300N and other network devices
to a minimum - each wall or ceiling can reduce your BEC 7300N 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 aluminium 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
(at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate extreme
RF (radio frequency) noise.
