RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio frequency energy
and if not installed and used properly, that is, in strict accordance with the
manufacturer’s instructions, may cause interference to radio communication.
It has been tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart J of Part 15 of FCC rules,
which are designed to provide reasonable protection against such interference
when the equipment is operated in a commercial environment. Operation of
this equipment in a residential area is likely to cause interference, in which case
the user at his own expense will be required to take whatever measures may be
necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from
digital apparatus set out in the Radio Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de classe A prescrites dans le Règlement sur le
brouillage radioélectrique publié par Industrie Canada.

FCC REQUIREMENTS FOR
TELEPHONE-LINE EQUIPMENT
1. The Federal Communications Commission (FCC)
has established rules which permit this device to
be directly connected to the telephone network
with standardized jacks. This equipment should
not be used on party lines or coin lines.
2. If this device is malfunctioning, it may also be
causing harm to the telephone network; this
device should be disconnected until the source
of the problem can be determined and until the
repair has been made. If this is not done, the
telephone company may temporarily disconnect
service.
3. If you have problems with your telephone
equipment after installing this device, disconnect
this device from the line to see if it is causing the
problem If it is, contact your supplier or an
authorized agent.
4. The telephone company may make changes in its
technical operations and procedures. If any such
changes affect the compatibility or use of this
device, the telephone company is required to
give adequate notice of the changes.

3
MINIMODEM USB
5. If the telephone company requests information
on what equipment is connected to their lines,
inform them of:
a. The telephone number that this unit is
connected to.
b. The ringer equivalence number.
c. The USOC jack required: RJ-11C.
d. The FCC registration number.
Items (b) and (d) can be found on the unit’s FCC
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 RENs of all devices on any one
line should not exceed five (5.0). If too many
devices are attached, they may not ring properly.
6. In the event of an equipment malfunction, all
repairs should be performed by your supplier or
an authorized agent. It is the responsibility of
users requiring service to report the need for
service to the supplier or to an authorized agent.

MINIMODEM USB
2. Introduction
2.1 Description
The MiniModem USB incorporates V.90 technology,
which enables Internet connections at data rates up to
56 kbps over standard telephone lines. (Although V.90
technology is capable of downloads of up to 56 kbps,
FCC regulations currently restrict ISP modems to
downloads of 53 kbps.)
V.90 technology can send data downstream from the
Internet to your computer at these speeds because data
on the telephone network typically is converted from
digital to analog only once before it reaches your
modem. Upstream transmissions, and transmissions
between client modems, are limited to data rates of
33.6 kbps, as are downstream transmissions that are
converted more than once on the telephone network.
The MiniModem USB is a full-duplex intelligent
modem with V.42 error correction, V.42bis data
compression, and V.17 (14,400 bps), Class 1 and 2,
Group 3 fax capabilities.

2.2 Universal Serial Bus (USB)
Universal Serial Bus (USB), defined by a consortium of
industry leaders, permits connection of multiple low-
speed and medium speed computer peripheral devices
such as telephones, modems, printers, keyboards, mice,
and scanners, all from a single personal computer port.
The specification, based on an open architecture, is
quickly becoming a standard feature in new desktop
and notebook computers.
