CHAPTER 1

Introducing the SBG

1.1 Overview

This chapter introduces the main features and applications of the SBG. The SBG5500/3310 Series consists

of the following models:

• SBG5500-A

• SBG5500-B

• SBG3310-A

The SBG is a VDSL router and Gigabit Ethernet (GbE) gateway. It has one DSL port and Gigabit Ethernet

for super-fast Internet access over telephone lines. The SBG5500-A and SBG3310-A are Annex A and can

use the DSL port over POTS (Plain Old Telephone Service) with an R-J11 connection, while the SBG5500-B

and SBG3310-B are Annex B and use DSL port over ISDN (Internet Service Digital Network) with an RJ45

connection. The DSL port is backward compatible with ADSL, ADSL2 and ADSL2+ in case VDSL is not

available.

The SBG5500-A and SBG5500-B feature a Gigabit Ethernet (GbE) WAN with Small Form Factor Pluggable

(SFP) interface. SFP is also known as Fiber Optics interface. The GbE WAN with SFP has a dual-personality

combo design (GbE + Fiber) which enables increased bandwidth and extended coverage.

SBG Series Features

• Firewall with Secure Network Management

• Secure Access via VPN (IPsec, PPTP, L2TP)

• Supports both Packet Transfer Mode (PTM) and Asynchronous Transfer Mode (ATM).

The following table describes the port features of the SBG by model.

Only use firmware for your SBG’s specific model. Refer to the label on

the bottom of your SBG.

Use the USB port for file sharing or using a 3G/4G dongle for cellular WAN (Internet) backup connections.

1.2 Ways to Manage the SBG

Use any of the following methods to manage the SBG.

• Web Configurator. This is recommended for everyday management of the SBG using a (supported)

web browser.

• TR-069. SBG uses an auto-configuration server used to remotely configure your device via TR-069.

1.3 Good Habits for Managing the SBG

Do the following things regularly to make the SBG more secure and to manage the SBG more

effectively.

• Change the password. Use a password that’s not easy to guess and that consists of different types of

characters, such as numbers and letters. The password must have 6-64 printable characters [0-9][a-z]

[A-Z][!@#$%*].

• Write down the password and put it in a safe place.

• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working

configuration may be useful if the device becomes unstable or even crashes. If you forget your

password, you will have to reset the SBG to its factory default settings. If you backed up an earlier

configuration file, you would not have to totally re-configure the SBG. You could simply restore your

last configuration.

1.4 Applications for the SBG

Here are some example uses for which the SBG is well suited.

1.4.1 Internet Access

As a small business gateway your SBG has multiple WAN interfaces, including, 3G/4G, DSL, fiber and

Gigabit Ethernet to share the network traffic load. You can configure multiple WAN load balance and

failover rules to distribute traffic amongst the different interfaces.

If you have DSL Internet service, connect the DSL port to the DSL or modem jack on a splitter or your

telephone jack. You can also have multiple WAN services over one ADSL or VDSL. The SBG cannot work

in ADSL and VDSL mode at the same time.

If you prefer not to use a DSL line or you already have a broadband modem/router in your network, use

the Ethernet WAN or SFP port. The SFP and GbE ports work as a Combo port, which means there are two

physical ports in the SBG, but they share a same port number and GbE works as a backup for the SFP

port if both are connected. You can also use a 3G/4G dongle for cellular backup WAN (Internet)

connections.

Note: If you connect all WAN ports the priority order will be DSL, Combo (for SBG5500),

Ethernet WAN port (for SBG3310), and USB port.

Note: The ADSL and VDSL lines share the same WAN (layer-2) interfaces that you configure in

the SBG. Refer to Section 5.3 on page 58 for the Configuration > WAN / Internet > WAN

Setup screen.

Computers can connect to the SBG’s LAN ports.

You can also configure IP filtering on the SBG for secure Internet access. When the IP filter is on, all

incoming traffic from the Internet to your network is blocked by default unless it is initiated from your

network. This means that probes from the outside to your network are not allowed, but you can safely

browse the Internet and download files.

1.4.2 SBG’s USB Support

Use the USB port for file sharing or insert a 3G/4G dongle for cellular backup WAN (Internet) connections.

File Sharing

Use the USB port (built-in USB 2.0) to share files on USB memory sticks or USB hard drives (B). Use FTP to

access the files on the USB device.
