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.

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.
•

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:
•
6 (47)
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.
PPP (Point to Point Protocol) over ATM (RFC 2364)
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.
1.4
•
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.

most likely marked with the standard USB symbol.
Important Notes on attaching other USB Devices:
If you are going to attach other USB devices, such as USB mouse, keyboard or
hub, please plug them to your PC before connecting the modem. Otherwise, the
pre-attached USB modem will consume a fixed bandwidth and the remaining
bandwidth will not be enough for other USB devices.
If this is the case, you will se an error message warning you that the USB
controller bandwidth is exceeded. The additional USB device may not function
properly.
For example, your modem is attached already and you need to add an USB mouse
to your PC. In this case:
•
•

Verifying your ADSL Connection
When the installation procedure has been completed, you can use the Control Panel to
view the current modem status regarding performance and ADSL connection.
4.1
Using the ADSL Modem icon
During driver installation, an ADSL Modem monitoring program is also installed on
your system. Whenever you start Windows, the utility is launched automatically with
its icon loaded in your system tray to indicate whether the physical connection
between your USB modem and the ISP is up or down:
If the ADSL Modem icon does not appear in your system tray, you can manually start
the utility by double-clicking the ADSL Modem HM121dp/di icon in the Control
Panel. This opens the Modem Control Panel and launches the utility icon at the same
time.
The ADSL Modem icon consists of two arrows. The upward arrow indicates data is
being transmitted whereas the downward arrow indicates data is being received. The
arrows are flashing yellow alternatively to indicate that trianing is in progress.
To identify the connection status, you can also move the cursor over the icon to see
the pop-up text as the following examples:
The physical link over the ADSL line is essential before you make a connection to
your ISP or corporate networks. If your ADSL connection fails, contact your ISP or
system administrator for troubleshooting.

Verifying your ADSL Connection
Figure 17: Control Panel - Physical Link tab
State indicates TRAINING when the ADSL line is "training" to achive the optimum
transmission rate. Once the line is trained the indication is changed to DATA. When
no ADSL signal is present the indication is NO SIGNAL.
Modulation shows the ADSL mode used. The setting is determined by the service
offered by your ADSL service provider and is normally either T1.413, G.Dmt or
G.Lite.
Data Rate(kbps) shows the transmission rate. The value for "Transmit" shows the
speed (kbps) from your computer to the ISP/service provider (uploading), while the
value for "Receive" shows the speed from the ISP/service provider to your computer
(downloading).
The indicator (circle) below Link Status blinks green when the ADSL line is
"training" to achieve the optimum transmission rate, and turns solid green when the
line is trained and ready for use. Individual flashing yellow indicators show the "Data
Activity" separately.
4.2.2

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.

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.

plugging.
User name
A name used to gain access to a computer system. User names (and often passwords)
are required in multiuser systems.
VPI and VCI
A VPI (Virtual Path Identifier) is an 8-bit field while VCI (Virtual Channel
Identifier) is a 16-bit field in the ATM cell header. A VPI identifies a link formed by
a virtual path and a VCI identifies a channel within a virtual path. A unique and
separate VPI/VCI identifier is assigned in advance to indicate which type of cells
