1: Introduction
2 Introduction 2.1 What is ADSL technology? Asymmetric Digital Subscriber Line (ADSL) is a technology for transmitting digital information at high speed on existing telephone lines to homes and businesses. Unlike a regular, dial-up telephone service, ADSL provides a continuously available, “always-on” connection. ADSL was specifically designed to exploit the asynchronous nature of most multimedia communication in which the user can obtain large amounts of information and only a small amount of interactive control information is returned. ADSL circuits can support data rates of up to 8 Mbps downstream from the network service to the user; and 1 Mbps upstream from the user to the network service.
2.2 ADSL connections ADSL access services typically use the Asynchronous Transfer Mode (ATM) protocol to provide a low level communications path between the user's access equipment and the service provider head end. The head end may be a Broadband Access Server (BAS) that sits, logically, behind the ADSL central office Digital Subscriber Line Access Multiplexer (DSLAM) and is connected using an ATM backbone. ATM is a high-speed switching technology where data is grouped into cells. Connection between the user equipment and the BAS is then achieved using the Point-toPoint Protocol (PPP) running over the ATM connection path. PPP is a defined industry standard used widely to allow two devices to communicate across a logical link. It is extensively deployed by service providers as a means of connecting customers to Internet Protocol (IP)-based services, such as the Internet.
Figure 1: PPP over a DSL connection The method of running PPP between the user equipment and the BAS may be either directly over the ATM layer (PPPoA) or over an intermediate Ethernet layer (PPPoE).

1: Introduction
2.3 ADSL connection options on your SMG You can configure two main types of ADSL service on your Service Managed Gateway:
ADSL Routed PPP Connection
ADSL Bridged Connection
If you select the Routed PPP service, you can run the PPP over ATM (PPPoA) or over Ethernet (PPPOE). The following diagrams illustrate the topology of these connections.
Figure 2: A routed ADSL connection over PPPoA

1: Introduction
Figure 3: A routed ADSL connection over PPPoE Less commonly, you may need to configure a bridged connection over ADSL. A bridge is a device that connects two local networks, and forwards packets between them. If your ADSL service is delivered as a bridged connection, the SMG has no visibility of the IP, or other protocol. This type of service is often associated with single PC user connections where the higher level 'routing' is performed in the PC client software.

1: Introduction
2.4 What is 3G technology? 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-2000. 3G 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 GW7000 Service Managed Gateway (SMG) 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 GW7000 supports a maximum download speed of 7.2 Mbps and a maximum upload speed of 2Mbps.
2.5 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.
2.5.1
GPRS GPRS (General Packet Radio Service) uses packet-switched technology to transmit small bursts of data. The 3G modem on the GW7000 SMG 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.
2.5.2
HSDPA HSDPA (High-Speed Downlink Packet Access) uses circuit-switched technology to transmit data at speeds of up to 1.8Mbps.
2.5.3
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.
