3 1: About this document 1 About this document 1.1 Scope This configuration guide explains how to set up and configure a primary link using the GSM (3G) modem on a GW2040 Series router. 1.2 Readership This document is for engineers who have previous experience configuring and managing GW Series routers. 1.3 More information Assigned interface number Throughout this guide we have used ppp-2 as the assigned interface number. You can configure any PPP interface number for connections. For example, ppp-1 could be substituted for each ppp-2 task covered in this document References to GSM (3G) The GW2040 web interface refers to GSM, not 3G, so screen grabs of the web interface will vary. 1.4 Terminology Abbreviation APN GSM HSDPA UMTS EDGE Description Access Point Name Global System for Mobile communications High-Speed Downlink Packet Access Universal Mobile Telecommunications System Enhanced Data rates for GSM Evolution 1.5 Prerequisites Inserting the SIM card Ensure the unit is powered off. Hold the SIM card with the chip side facing down and the cut corner top left. Gently push the SIM card into SIM slot 1 until it clicks in. To remove the SIM card, gently push the SIM card. The card will click out. WARNING The SIM card MUST be inserted into the SMG before the unit is powered on. Issue: 1.5 Page 3 of 34

4 1: About this document Do not insert or remove the SIM card after the unit has been powered on Internet Service Provider details Before you configure the GSM (3G) modem, check with your Internet Service Provider for the following information: Number Username and password PIN PUK, and Access Point Name Issue: 1.5 Page 4 of 34

5 2: Introduction 2 Introduction 2.1 3G overview 3G is the third generation of mobile phone standards and technology. It is based on the International Telecommunication Union (ITU) family of standards under the International Mobile Telecommunications programme, IMT G technologies enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. Services include wide-area wireless voice telephony, video calls, and broadband wireless data, all in a mobile environment. The GW2040 Series router contains a GSM (Global System for Mobile communications) 3G wireless modem. The modem in connection with a SIM card establishes a WAN connection to the Internet. The GW2040 Series router supports a maximum download speed of 7.2 Mbps and a maximum upload speed of 384 kbps. 2.2 Typical uses of the GSM (3G) modem You can use the GSM (3G) modem on the GW2040 Series 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 GW2040 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. Issue: 1.5 Page 5 of 34

6 2: Introduction Figure 2: A primary link using the 3G modem on the GW2040 series router 2.3 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 GPRS GPRS (General Packet Radio Service) uses packet-switched technology to transmit small bursts of data. The maximum data rate available to the 3G modem depends on provisioning by the network operator HSDPA HSDPA (High-Speed Downlink Packet Access) uses circuit-switched technology to transmit data at speeds of up to 7.2Mbps HSUPA HSUPA (High-Speed Uplink Packet Access) is a 3G mobile telephony protocol with up link speeds of 5.76Mbps UMTS UMTS (Universal Mobile Telecommunications System) is a 3rd generation technology providing higher transfer rates Edge Edge uses the same frequencies as GPRS but offers better speeds. It is used when the signal strength for 3G is not sufficient. Issue: 1.5 Page 6 of 34

7 3: Configuring the 3 Configuring the GW2040 series The GW2040 Series contains an internal web server that is used to configure the router. Before you can access the internal web server and start the configuration, you must ensure that your PC has the correct networking set up. When your GW2040 Series router is correctly connected to your PC, type fast.start into the URL line of your browser to display the start page. Alternatively, you can type in the IP address of the gateway. Figure 3: The GW2040 series web interface 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 GW2040 Series router. Issue: 1.5 Page 7 of 34
