CHAPTER 1: INTRODUCTION

Introduction to your BEC Device

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 integrates multiple WAN options ADSL2+ / VDSL2 interface and a second

10/100/1000 Gigabit Ethernet WAN interface which can be used for broadband connectivity to any

other Ethernet broadband device. Service Providers can benefit from flexible development options,

offering a wide range of service package for subscribers, reducing truck roll when subscribes

upgrading package plan providing possible lifespan for the investment all in one unit.

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 gateway is also controlled to ensure that users do not saturate bandwidth

with their browsing activities.

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 existing 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.

Introduction

BEC 8920AC User Manual

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.

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.

Quick Start Wizard

Support a WEB GUI page to install this device quickly. With this wizard, simple steps will get you

connected to the Internet immediately.

Firmware Upgradeable

Device can be upgraded to the latest firmware through the WEB based GUI.

Product Overview

System Recovery Procedure & Cabling

13

BEC 8920AC User Manual

System Recovery Procedures

The purpose is to allow users to restore the POWER to its initial stage when the device is outage,

upgraded to a wrong / broken firmware, cannot access to the GUI with wrong username and/or

password, etc.

Step 1 – Configure your PC Network IP Address

Before performing the system recovery, assign this IP address and Netmask to your PC,

192.168.1.100 and 255.255.255.0 respectively.

Step 2 – Reset your 8920AC Device

2.1 Power off your 8920AC.

2.2 Power on the 8920AC while pushing the RESET button with a small pointed object (such as

paper clip, needle, toothpick, etc.).

2.3 When the POWER LED turns RED, keep holding and pushing the RESET button until the GbE

LAN LED flashes in GREEN.

Step 3 – Restore your 8920AC Device

3.1 Open a web browser and type the IP address, 192.168.1.254, to access to the recovery page.

NOTE: In the recovery mode, 8920AC will not respond to any PING or other requests.

3.2 Browse to the new Firmware image file then click Upload to start the upgrade process.

3.3 The POWER LED stays in RED and GbE LAN LED flashes in green, it means the Firmware

upgrade is in process.

DO NOT power off or reboot the device, it would permanently damage your 8920AC.

3.4 POWER LED turns green after the Firmware upgrade completed.

3.5 You now should be able to access to the 8920AC GUI.

Cabling

One of the most common causes of problems is bad cabling. Make sure that all connected devices

are turned on. On the front panel of the product is a bank of LEDs. Verify that the LAN Link and LEDs

are lit. If they are not, verify that you are using the proper cables.

Basic Installation

14

BEC 8920AC User Manual

CHAPTER 3: BASIC INSTALLATION

The router can be configured with your web browser. A web browser is included as a standard

application in the following operating systems: Windows 10 / 8 / 7/ Vista, Linux, Mac OS, etc. The

product provides an easy and user-friendly interface for configuration.

PCs must have an Ethernet interface installed properly and be connected to the router either directly

or through an external repeater hub and have TCP/IP installed or configured to obtain an IP address

through a DHCP server or a fixed IP address that must be in the same subnet as the router. The default

IP address of the router is 192.168.1.254 and the subnet mask is 255.255.255.0 (i.e. any attached PC

must be in the same subnet and have an IP address in the range of 192.168.1.1 to 192.168.1.253).

The best and easiest way is to configure the PC to get an IP address automatically from the router

using DHCP. If you encounter any problems accessing the router’s web interface it may also be

advisable to uninstall any kind of software firewall on your PCs, as they can cause problems

accessing the 192.168.1.254 IP address of the router. Users should make their own decisions on how

to best protect their network.

Please follow the steps below for your PC’s network environment installation. Check your PC’s network

components first. The TCP/IP protocol stack and Ethernet network adapter must be installed. If not,

please refer to your Windows-related or other operating system manuals.

Any TCP/IP capable workstation can be used to communicate with

or through the 8920AC. To configure other types of workstations,

please consult the manufacturer’s documentation.
