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.

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)
Introduction
EN/LZT 108 6429 R1 7 (47)
May 2003
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.
