Chapter 1: Introduction
Introduction to your 7402 Series Router
Welcome to the BEC 7402 Series Router. The router is an “all-in-one” unit, combining an ADSL modem,
IEEE 802.11g wireless access point (optional), ADSL router with four-port 10/100M auto-crossover
Switch, and Firewall, enabling you to maximize the potential of your existing resources. The 7402 can
provide everything you need to get the machines on your network connected to the Internet over your
ADSL broadband connection. It supports the latest ADSL2/2+ technology enabling high-speed data
rates of up to 24Mbps, Its powerful QoS feature for traffic priority and bandwidth management, and
security features including multiple VPN tunnels (optional) with 3DES make the device a perfect mate to
the office user or for anyone who has the compelling needs to transmit sensitive data more securely.
With integrated 54Mbps 802.11g Access Point (optional) in this device, the router brings up the
productivity and mobility to office users.
With features such as an ADSL Quick-Start wizard and DHCP Server, you can be online in no time at all
and with a minimum of fuss and configuration, catering for first-time users to the guru requiring
advanced features and control over their Internet connection and network.
Features
The 7402 ADSL2+ Triple Play Router combines high-speed Internet access, networking, and
advanced security for office local area network. It provides:
Express Internet Access – capable of ADSL2/2+
The router complies with ADSL worldwide standards. It supports downstream rates up to 8Mbps
with ADSL, capable of up to 12/24 Mbps with ADSL2/2+, and upstream rates 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 much easier and faster than ever. It 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); G.dmt.bisplus (ITU G.992.5)).
Wireless Ethernet 802.11g (Optional)
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. An Ethernet straight or crossover cable can be used
directly for auto detection.
Multi-Protocol to Establish A Connection
Supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483 encapsulation over
ATM (bridged or routed), PPP over Ethernet (RFC 2516) and IPoA (RFC1577) to establish a
connection with the ISP. The product also supports VC-based and LLC-based multiplexing.
Quick Installation Wizard
Supports a WEB GUI page to install this device quickly. With this wizard, end users can enter the
information easily which they get from their ISP, then surf the Internet immediately.

Chapter 1: Introduction

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. It makes network simple and affordable for users. UPnP
architecture leverages TCP/IP and the Web to enable seamless proximity networking in addition to
control and data transfer among networked devices. With this feature enabled, users can now
connect to Net meeting or MSN Messenger seamlessly.
Network Address Translation (NAT)
Allows multi-users to access outside resources such as the Internet simultaneously with one IP
address/one Internet access account. Many application layer gateway (ALG) are supported such
as web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping, NetMeeting, IP phone and
others.
Firewall
Supports SOHO firewall with NAT technology. Automatically detects and blocks Denial of Service
(DoS) attacks. The URL blocking, packet filtering and SPI (Stateful Packet Inspection) are also
supported. The hacker’s attack will be recorded associated with timestamp in the security logging
area. More firewall functions will always be implemented through updated firmware releases.
Domain Name System (DNS) relay
Provides an easy way to map the domain name (a friendly name for users such as
www.yahoo.com) and IP address. When local machine sets its DNS server with this router’s IP
address, every DNS conversion request packet from the PC to this router will be forwarded to the
real DNS in 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. For example, to use the service, you must first apply
for an account from a DDNS service like http://www.dyndns.org/. More than 5 DDNS servers are
supported.
PPP over Ethernet (PPPoE)
Provides embedded PPPoE client function to establish a connection. Users can get greater
access speed without changing the operation concept, sharing the same ISP account and paying
for one access account. No PPPoE client software is required for local computer. The Automatic
Reconnect and Disconnect Timeout (Idle Timer) functions are provided, too.
Virtual Private Network (VPN) (Optional)
Allows user to make a tunnel with a remote site directly to secure the data transmission among the
connection. User can use embedded PPTP and L2TP client/server, IKE and IPSec which are
supported by this router to make a VPN connection or users can run the PPTP client in PC and the
router already provides IPSec and PPTP pass through function to establish a VPN connection if
the user likes to run the PPTP client in his local computer.
Virtual Server (“port forwarding”)
Users can specify some services to be visible from outside users. The router can detect incoming
service requests and forward either a single port or a range of ports to the specific local computer
to handle it. For example, a user can assign a PC in the LAN acting as a WEB server inside and
expose it to the outside network. Outside users can browse inside web servers directly while it is
protected by NAT. A DMZ host setting is also provided to a local computer exposed to the outside
network, Internet.
Rich Packet Filtering
Not only filters the packet based on IP address, but also based on Port numbers. It will filter
packets from and to the Internet, and also provides a higher level of security control.

Dynamic Host Configuration Protocol (DHCP) client and server
In the WAN site, the DHCP client can get an IP address from the Internet Service Provider (ISP)
automatically. In the LAN site, the DHCP server can allocate a range of client IP addresses and
distribute them including IP address, subnet mask as well as DNS IP address to local computers. It
provides an easy way to manage the local IP network.
Static and RIP1/2 Routing
Supports an easy static routing table or RIP1/2 routing protocol to support routing capability.
Simple Network Management Protocol (SNMP)
It is an easy way to remotely manage the router via SNMP.
Web based GUI
Supports web based GUI for configuration and management. It is user-friendly and comes with on-
line help. It also supports remote management capability for remote users to configure and
manage this product.
Firmware Upgradeable
Device can be upgraded to the latest firmware through the WEB based GUI.
Rich management interfaces
Supports flexible management interfaces with local console port, LAN port, and WAN port. Users
can use terminal applications through the console port to configure and manage the device, or
Telnet, WEB GUI, and SNMP through LAN or WAN ports to configure and manage the device.
