FCC - Class B

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with instructions, may cause harmful interference to radio communications. However, there is no guarantee that the interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient the receiving antenna

• Increase the separation between the equipment and receiver

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected

• Consult the dealer or an experienced radio/TV technician for help

FCC - Part 68

The modem is registered with the FCC as compliant with the rules of Part 68 and use of this modem is subject to the following restrictions:

1. The Federal Communication Commission FCC has established rules which permit this device to be directly connected to the telephone network. Standardized jacks are used for these connections. This equipment should not be used on party lines or coin phones.

Items (b) and (d) are indicated on the label. The Ringer Equivalence Number (REN) is used to determine how many devices can be connected to your telephone line. In most areas, the sum of the REN of all the devices on any one line should not exceed 5.0. If too many devices are attached, they may not ring properly.

Industry Canada Required Information

EQUIPMENT ATTACHMENTS LIMITATIONS

To ensure that certified equipment is attached correctly and only to the networks of participating carriers, the following statement shall accompany each unit of certified equipment offered for sale. This statement must be included conspicuously in written or electronic format, at or near the front of each copy of the operating manual, or accompany other technical information, or be included as a separate sheet. The required statement is:

“NOTICE: The Industry Canada label identifies certified equipment. This certification means that the equipment meets telecommunications network protective, operational and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The department does not guarantee the equipment will operate to the user’s satisfaction.”

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. The customer should be aware that compliance with the above conditions might not prevent degradation of service in some situations.

Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas. Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

An explanatory note on Ringer Equivalence Numbers (see Section 10.0) and their use must be provided for the terminal equipment user in the information accompanying the terminal equipment. A notice similar to the following would be suitable:

“NOTICE: The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone interface. The termination on an interface may consist of any combination of devices subject only to the requirement that the sum of the ringer equivalence Numbers of all the devices does not exceed 5.”

NTRODUCTION

The EZ Connect ADSL USB Modem (SMC7003USB V.2) provides high-speed Internet access over existing phone lines by making use of previously unused frequency bandwidth above the voice band. By placing ADSL (Asymmetric Digital Subscriber Line) signals above the frequency of the voice signal, ADSL service can coexist on the same line with your telephone service. ADSL is asymmetric in 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 EZ Connect ADSL USB Modem supports both full-rate Discrete Multi-Tone (G.dmt) connection (T1.413, Issue II) and the more economical G.lite connection (G.992.2). This modem delivers concurrent data and voice over a single connection. It also supports a Rate Adaptive algorithm to maintain high data integrity under existing conditions, including varied connection lengths and degraded signal quality. Because all data is encapsulated in ATM frames, the EZ Connect ADSL USB Modem can be connected directly to any standards-compliant DSL Access Multiplexer (DSLAM) at your service provider’s central office, data is then sent through an ATM backbone, and out to the Internet via an ISP router. Moreover, there is no need to install any new line.

1-1

NTRODUCTION

This plug-in ADSL modem provides an always-on digital connection that eliminates dial-up delays, and transparent reconnection when initiating any network request. Full support for the ATM protocol also provides access to a wide range of advanced transport features, including support for real-time video, and other multimedia services requiring guaranteed Quality of Service (QoS). This device enables true telecommuting for the first time by providing complete access to Internet and corporate resources via multiprotocol encapsulation (including TCP/IP, Novell’s IPX, and Windows NetBEUI network protocols).

Note: Since this modem supports both G.dmt and G.lite, it requires an

external splitter to separate the traffic entering your premises into data and voice, and also to merge the data and voice traffic leaving your premises into a single stream.

ARDWARE INSTALLATION

Hardware Description

Setting up the EZ Connect ADSL USB Modem involves connecting the device’s cables and installing the driver software. Note that Windows 98, 98SE, 2000, XP, or Macintosh 9.x should already be installed on the computer before installing the driver software.

ARDWARE DESCRIPTION

LED Indicators

The EZ Connect ADSL USB Modem has two LEDs on the top panel, one is marked “Data” and the other “Power.” The operational status of the

modem is indicated by the LED conditions listed below

LED Status Description

Data Flashing Indicates the modem is synchronizing its ADSL/

ATM link with the head end.

On Indicates an ADSL/ATM link has been established

on the RJ-11 port.

Power On Power is being supplied to the modem via the USB

bus.

Power Requirements

USB devices can be either self-powered or bus-powered. A device which has no power connector is bus-powered, and derives its operating power from the USB connection directly. The EZ Connect ADSL USB Modem is bus-powered — all you need to do is plug it into a host PC or self-powered USB hub.
