1.3.5 Terminology

Abbreviation Description GSM Global System for Mobile communications UMTS Universal Mobile Telecommunications System HSDPA High-Speed Downlink Packet Access


2: Introduction

2 Introduction The Service Managed Gateway (SMG) contains a GSM (Global System for Mobile communications) 3G wireless modem. The modem uses a SIM card to create a dial-up WAN connection to the Internet.

2.1 Typical uses of the GSM (3G) modem

You can use the GSM (3G) modem on the GW Series router in two ways.

• You can create a primary WAN link over the GSM (3G) modem.

Figure 1: A primary WAN link over the 3G modem

• You can use the GSM (3G) modem as a backup WAN link. If the primary interface link fails, the GW Series router uses its GSM (3G) modem to automatically route traffic across the Internet via its alternative interface. This set up is not covered in this document. For further information contact Virtual Access.

Figure 2: A primary link using the 3G modem on the GW SERIES ROUTER SMG

2.2 Types of data bearers that the GSM (3G) modem supports

Data bearers are frame protocols that transport data streams. The GSM (3G) modem supports GPRS, HSDPA, and CSD.


2: Introduction

2.2.1 GPRS

GPRS (General Packet Radio Service) uses packet-switched technology to transmit small bursts of data. The 3G modem on the GW Series router supports multi-slot class 6, which allows a maximum data rate of 384Kbps class 3. The maximum data rate available to the 3G modem depends on provisioning by the network operator.

2.2.2 HSDPA

HSDPA (High-Speed Downlink Packet Access) uses circuit-switched technology to transmit data at speeds of up to 1.8Mbps.

2.2.3 CSD in EGSM900/GSM1800 MHz

CSD (Circuit-Switched Data) mode enables the 3G modem to transmit data over the EGSM (Extended Global System for Mobile communications) frequency or the GSM frequency. The modem behaves as a dual-band mobile phone behaves.


3: Configuring the SMG

3 Configuring the SMG The Service Managed Gateway (SMG) contains an internal web server that is used to configure the SMG. Before you can access the internal web server and start the SMG configuration, you must ensure that your PC has the correct networking set up.

To enable and configure connections on your SMG, the gateway must be correctly installed, and a valid service must be configured on it.

When your Service Managed Gateway is correctly connected to your PC, type fast.start into the URL line of your browser to display the Start page.

Figure 3: The SMG start page

If a login page appears type in the login password you received from your administrator.

If you have not received a password, contact the Virtual Access Support team.

Access the Fast Start Wizard by clicking the Fast.Start icon on the Start page of the embedded web.

The Fast Start Wizard will guide you through a series of forms that you must complete to configure your SMG.


4: Setting up the GSM (3G) modem for a primary WAN link

4 Setting up the GSM (3G) modem for a primary WAN link You set up the GSM (3G) modem for a primary WAN link in the Expert View of the Advanced section of the web of the SMG.

On the SMG Start page, click Advanced.

In the Advanced menu, click Expert View.

4.1 Configuring the GW Series router to use the GSM (3G) modem interface

To configure the GW Series router to use the GSM (3G) modem interface, follow the steps in sections 4.1.1 to 4.1.10. You do not have to save each configuration until you have updated all your settings. When you have completed all your configuration changes, you must save the configuration as described in section 4.1.11.

4.1.1 Configure the IP default route

In the Expert View menu, select system -> ip -> default route. The IP Default Route page appears.

Figure 4: The IP default route page
