1.2 About ADSL

The ADSL (Asymmetric Digital Subscriber Line) technology provides high-speed data access across regular phone lines (copper wires) by making use of previously unused frequency bandwidth above the voice band. By placing the ADSL signal above the frequency of the voice signal, ADSL service is able to coexist on the same line with your telephone service. ADSL is symmetric in the sense that it provides a higher data rate in the downstream (receive) direction than in the upstream (transmit) direction. Asymmetric operation is ideal for typical home and small office use where files and information are downloaded more frequently than uploaded.

The HM121dp/di is capable of supporting the following DSL standards: ANSI T1.413 Issue 2, ITU G.992.1 (G.DMT), ITU G.992.2 (G.lite), and ITU G.992 Annexes A, B and C as applicable.

EN/LZT 108 6429 R1 5 (47) May 2003

Introduction

1.3 About the ADSL Modem HM121dp/di

The Ericsson ADSL Modem HM121d comes in two versions: HM121dp and HM121di. Both products offer the same features, but they rely on different types of telephone line in order to provide the ADSL service.

HM121dp offers ADSL service over POTS (Plain Old Telephone System) lines, while HM121di uses ISDN (Integrated Services Digital Network) lines to provide the ADSL service.

The HM121dp/di is easily connected to a USB port on the PC via a standard USB cable (supplied). The modem uses power from the PC via the USB cable, which eliminate the need of a power cable and AC adapter. An intuitive self-installation wizard then guides the user step-by-step through the entire software installation process. When new features and updates of the modem's software are available, they may be added by simply loading a new version of the device driver onto the PC.

The main features of the HM121dp/di are listed below:

• Compliant with Universal Serial Bus Specification Revision 1.1.

• USB bus-powered; an external power supply is not required.

• Supports two device drivers: Microsoft NDIS 4.0 WAN Miniport and NDIS 4.0

LAN Miniport.

• Compatible with T1.413 i2, G.DMT, and G.lite compliant CO DSLAM

equipment.

• Up to 8 Mbps downstream and at least 640 Kbps upstream for full-rate operation.

Note:

The actual rate depends on the copper category of your telephone wire, distance from the central office and the type of ADSL service subscribed to. Also, if other USB devices are attached to your computer sharing the fixed bandwidth of USB controller, the performance of the USB modem will be slightly influenced and thus effects the actual speed.

• Software upgradeable.

• Support for PPP over Ethernet (PPPoE).

• Includes a Microsoft Windows control panel monitoring program for configuring

the adapter and checking the status of the connection.

1.3.1 Protocol and Device Driver Selection

ADSL modems employ ATM (Asynchronous Transfer Mode) framing. ATM is a protocol that divides packets into small fixed sized cells for rapid transmission over high-speed networks. The ATM protocol allows various types of traffic (e.g. data, voice, and video) to be securely and efficiently carried over the same network. ATM is being widely deployed by telecommunications carriers in their backbone networks.

Several different protocols are used on top of ATM. The protocol required in your configuration depends on the equipment deployed by your ADSL service provider. There are several possibilities:

• PPP (Point to Point Protocol) over ATM (RFC 2364)

6 (47) EN/LZT 108 6429 R1

May 2003

Introduction

PPP provides session setup, user authentication (login), and encapsulation for upper layer protocols such as IP (Internet Protocol). The use of PPP makes the modem appear as a dial-up modem to the operating system and Dial-Up Networking is used to establish a connection.

• Bridged Ethernet over ATM (RFC 1483B) / Routed IP over ATM (RFC 1483R).

This protocol makes the modem appear as a LAN (Local Area Network) device to the operating system.

• Classical IP over ATM (RFC 1577)

This is another LAN alike protocol for IP address and ATM address mapping.

• PPP (Point to Point Protocol) over Ethernet (RFC 2516)

This protocol, commonly called PPPoE, allows multiple computer users on an Ethernet to share a common ADSL connection to the Internet.

For the HM121dp/di there are two types of device drivers available: WAN and LAN which both support the ATM protocol.

• WAN driver

This driver causes the modem to resemble a dial-up modem. Call establishment is performed through Dial-Up Networking. This driver supports PPP over ATM (RFC 2364) with PVC connections. PPP over Ethernet (RFC 2516) is embedded into this driver.

• LAN driver

This driver makes the modem appear as a LAN or Ethernet device. The connection establishment is automatic. This driver supports Bridged Ethernet over ATM (RFC 1483B) and Routed IP over ATM (RFC 1483R) with PVC connections. Classical IP over ATM (RFC 1577) is also supported by this driver.

PPPoE is supported via third party software when implemented with a LAN driver. After installing the LAN driver, follow the installation instructions provided with the third party PPPoE software. The third party software will search for existing drivers and Internet connection will be made through the third party software. You will be required to enter your User name and Password.

Glossary

ADSL

Short for Asymmetric Digital Subscriber Line, a technology that allows more data to be sent over existing copper telephone lines (POTS). ADSL support data rates of fromm 1.5 to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data (known as the upstream rate).

ATM

Short for Asynchronous Transfer Mode, a network technology based on transferring data in cells or packets of a fixed size. The cell used with ATM is relatively small compared to units used with older technologies. The small, constant cell size allows ATM equipment to transmit video, audio, and computer data over the same network, and assure that no single type of data hogs the line.

Device

Any machine or component that attaches to a computer. Examples of devices include disk drives, printers, mice, and modems.

DHCP

Short for Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network. In some systems, the device's IP address can even change while it is still connected. Many ISP's use dynamic IP addressing for dial-up users.

Downstream

The direction of a downstream signal is from the ISP/service provider to the user's computer (downloading).

DSL

Short for Digital Subscriber Line, which is a data communications technology that transmits information over the existing copper telephone lines (POTS). DSL takes existing voice cables that connect customer premises (CPE) to the phone company's central office (CO) and turns them into a high-speed digital linke. There are many types of DSL and ADSL is one of them.

DSLAM

Short for Digital Subscriber Line Access Multiplexer, a mechanism at a phone company's central location that links many customer DSL connections to a single high-speed ATM line.

When the phone company receives a DSL signal, an ADSL modem with a POTS splitter detects voice calls and data. Voice calls are sent to the PSTN, and data re sent to the DSLAM, where it passes through the ATM to the Internet, then baack through the DSLAM and ADSL modem before returning to the customer's PC.

Firmware

Software (programs or data) that has been written onto read-only memory (ROM). Firmware is a combination of software and hardware.

G.dmt

A kind of asymmetric DSL technology, based on DMT modulation, that offers up to 8 megabits per second downstream bandwidth, 1.544 Megabits per second upstream bandwidth. "G.dmt" is actually a nickname for the standard officially known as ITU-T Recommendation G.992.1.

G.lite

A kind of asymmetric DSL technology, based on DMT modulation, that offers up to

1.5 megabits per second downstream bandwidth, 384 Kilobits per second upstream, does not usually require a splitter and is easier to install than other types of DSL. "G.lite" is a nickname for the standard officially known as G.992.2.

IP address

An identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based on the IP address of the destination. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.

ISP

Short for Internet Service Provider, a company that provides access to the Internet.

LAN

Short for Local Area Network, a computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings and connect workstations and personal computers. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN).

There are many different types of LANs, where Ethernet being the most common for PCs.

LED

Short for Light Emitting Diode, a type of control lamp on devices that indicates the status of a device.

Password

A secret series of characters that enables a user to access a file, computer, or program. On multiuser systems, each user must enter his or her password before the computer will respond to commands.

POTS

Short for Plain Old Telephone Service, which refers to the standard telephone service that most homes use. The POTS network is also called the Public Switched Telephone Network (PSTN).

PPP

Short for Point-to-Point Protocol, a method of connecting a computer to the Internet. PPP sends the computer's TCP/IP packets to a server that puts them onto the Internet.

T1.413

The American National Standards Institute (ANSI) standard for asymmetric digital subscriber line using discrete multitone modulation, which the G.dmt standard is based on.)

TCP/IP

Short for Transmission Control Protocol / Internet Protocol, the suite of communication protocols used to connect hosts on the Internet.

Upstream

The direction of an upstream signal is from the user's computer to the ISP/service provider (uploading).
