CHAPTER 1: INTRODUCTION
Introduction to Your Router
Thank you for purchasing BEC 8920AC_The Ultimate Residential Gateway with 802.11ac. This
unit is an all-in-one Universal Bonded Gateway supporting ultra-broadband triple-play services via
multiple WAN connection options. Service providers can utilize one gateway for all major broadband
technologies such ADSL2+, VDSL2, xDSL bonding and FTTH. In addition to offering the multiple
WAN connection options, the 8920AC integrates multiport Ethernet switching and routing,
802.11a/b/g/n/ac Wireless networking, advanced firewall security including stateful packet inspection,
Quality of Service (QoS) and remote management. Users can easily enjoy high bandwidth services
such as High Definition IPTV, streaming video, interactive gaming, over-the-top (OTT) applications to
multiple devices throughout the home.
Flexible Deployment Options
The BEC 8920AC provides service operators with flexible, scalable deployment options optimized to
both reduce costs and provide the longest possible lifespan for the investment. The BEC 8920AC
integrates dual WAN options; a VDSL2/ADSL2+ interface and a second 10/100/1000 Ethernet WAN
interface which can be used for broadband connectivity to any other Ethernet broadband device.
Operators can now deploy one device to support current and future network migration.
Quality of Service
Quality of Service (QoS) gives users’ full control over outgoing data traffic. Priority can be assigned by
the router to ensure that important transmissions like gaming packets, VoIP calls or IPTV/streaming
content passes through the router at lightning speed, even when there is heavy Internet traffic. The
speed of different types of outgoing data passing through the gateway is also controlled to ensure that
users do not saturate bandwidth with their browsing activities.
Robust Firewall Security
The NAT default firewall has advanced anti-hacker pattern-filtering protection features that
automatically detect and block Denial of Service (DoS) attacks. In addition, Packet Filtering provides
high-level security for access control. Built with Stateful Packet Inspection (SPI), the router enables
users to determine whether or not a data packet is allowed to pass through the firewall to the private
LAN.
Dual Concurrent Wireless with Superior 802.11ac Speed & Ultimate Coverage
With the next wireless generation, 802.11ac, integrated in the 8920AC, the router delivers speed as
fast 1.3 gigabit per second. Wireless AC provides high-throughput wireless speed by taking the
advantage of frequency on the 5GHz band with less interference and using the beamforming
technology to enable a direct signal focus on the Access Point and a wireless client to extend wireless
coverage area. The 8920AC supports a link rate up to 300Mbps in 2.4GHz frequency range &
1300Mbps in 5GHz range and is also backward compatible with exiting 802.11 a / b / g / n equipment
in the network. The Wireless Protected Access (WPA-PSK/WPA2-PSK) and Wireless Encryption
Protocol (WEP) features enhance the level of transmission security and access control over Wireless

LAN. The router also supports the Wi-Fi Protected Setup (WPS) standard for easy and secure
establishment of a wireless home network. If the user’s network requires wider coverage, the built-in
Wireless Distribution System (WDS) repeater function expands the wireless network without needing
any external wires or cables.
Pathway to the Future
The BEC 8920AC fully supports IPv6 (Internet Protocol Version 6), implementation of IPv6 is growing
significantly and multiple transition methods are required to support the coexistence and migration
from IPv4. With BEC IPv6 enabled devices, service providers easily adapt IPv6 to their network as we
support major transition mechanisms such as Dual-Stack, Dual-Stack Lite, and 6RD.
