*IMPORTANT! In accordance with the ITU-T standard for 56K transmissions (V.90), this modem is capable of 56 Kbps down-
loads. However,the download speeds you experience may be lower due to varying line conditions and other factors. Uploads
from users to server equipment travel at speeds up to 31.2 Kbps. An analog phone line compatible with the V.90 standard and
an Internet provider or corporate host site compatible with the V.90 standard are necessary for these high-speed downloads.
IMPORTANT: If any numbers between 03 and 15 are missing
fromthe screen’s left column, skipto step 2. If allIRQs between 03
and 15 are listed, they are all being used by other devices. Your
modem needs one of these IRQs in order to function properly. To

majorityof telephonelinesin NorthAmericasupport 56Kconnections.
However,due tounusual oroldtelephonelineconfigurations,some
userswillnot beabletotake fulladvantageofthis technology.
Itisimportanttorememberthat your line conditions may change, so
youmaybeable to make faster connectionsinthefuture.Tomake
surethatyoucan use 56K technology,perform thefollowingtests:
1. First, make sure your modem supports V.90. You
canverifythat your modem supports V.90by opening a
terminalapplication(RapidComm,HyperTerminal,
ZTerm, etc.) typing ati7 and pressing ENTER. If the
Options line has V.90 listed, then your modem supports
3Com56Ktechnology.
2. Make sure that the number you’re dialing is an actual
V.90 server. Some ISPs may have amixture of V.90
and non-V.90 servers. You can check this by contacting
your ISP and asking them about 56K technology or
V.90 availability.
3. If it is a V.90 server, you may want to try calling it a few
moretimes.Remember,thephonecompanyroutes
each call in a different fashion each time you place a
call. For testing purposes, you may want to call into the
3ComBBSat847-262-6000,whichhasV.90 servers
attached to it.
4. If you are able to connect at V.90 speeds on the 3Com
BBS,there may be something between you and your
ISPthatispreventingaV.90 connection from being
negotiated. You may want to contact your ISP and see
iftheyhavereceivedsimilar reports from other
customers.
5. If you do not make a V.90 connection to our BBS, your
linemightnotbe capable of supporting V.90speeds. If
that’s the case, then see the next item in this list.
6. Ifyouareexperiencingconsistent problems with V.90

(1) this device may not cause harmful electromagnetic interference, and
(2) this device must accept any interference received including
interference that may cause undesired operations.
Part 68:
This equipment complies with FCC Rules Part 68. Located on the bottom
of the modem is the FCC Registration Number and Ringer Equivalence
Number (REN).
You must provide this information to the
telephone company if requested. The REN is used to determine the
number of devices you may legally connect to your telephone line. In most
areas, the sum of the REN of all devices connected to one line must not
exceed five (5.0). You should contact your telephone company to determine
the maximum REN for your calling area.
This equipment uses the following USOC jacks: RJ-11C.
This equipment may not be used on coin service provided by the
telephone company. Connection to party lines is subject to state tariffs.
An FCC compliant telephone cord and modular plug are provided with this
equipment, which is designed to connect to the telephone network or
premises wiring using a Part 68 compliant compatible jack. See
installation instructions for details.
Caution to the User
The user is cautioned that any changes or modifications not expressly
approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
Industry Canada (IC)
This digital apparatus does not exceed the Class B limits for radio noise
emissions from digital apparatus set out in the interference-causing
equipment standard entitled
Digital Apparatus , ICES-003 of Industry
Canada.
UL Listing/CUL Listing
This information technology equipment is UL-Listed and CUL-Listed for
use with UL-Listed personal computers that have installation instructions
detailing user installation of card cage accessories.
Radio and Television Interference
This equipment generates and uses radio frequency energy and if not
installed and used properly, in strict accordance with the manufacturer’s
instructions, may cause interference to radio and television reception. The
modem has been tested and found to comply with the limits for a Class B
computing device in accordance with the specifications in Part 15 of FCC
rules, which are designed to provide reasonable protection against such
interference in a residential installation.
However, there is no guarantee that interference will not occur in a
particular installation. If this device does cause interference to radio or
television reception, which you can determine by monitoring reception
when the modem is installed and when it is removed from the computer,
try to correct the problem with one or more of the following measures:
· Reorient the receiving antenna (for televisions with antenna reception
only) or cable input device.
· Relocate the computer with respect to the receiver.
· Relocate the computer and/or the receiver so that they are on separate
branch circuits.
If necessary, consult your dealer or an experienced radio/television
technician for additional suggestions. You may find the following booklet,
prepared by the Federal Communications Commission, helpful:
How to Identify and Resolve Radio-TV Interference Problems
Stock No. 004-000-0345-4
U.S. Government Printing Office
Washington, DC 20402
In accordance with Part 15 of the FCC rules, the user is cautioned that any
changes or modifications to the equipment described in this manual that
are not expressly approved by 3Com could void the user’s authority to
operate the equipment.
Connecting to the Telephone Company
It is not necessary to notify the telephone company before installing the
modem. However, the telephone company may request the telephone
number(s) to which the modem is connected and the FCC information
printed on this section.
Be sure that the telephone line you are connecting the modem to is a standard
analog line and not a digital (PBX), party, or coin telephone line.
If the modem is malfunctioning, it may affect the telephone lines. In this case,
disconnect the modem until the source of the difficulty is traced.
Fax Branding
The Telephone Consumer Protection Act of 1991 makes it unlawful for any person
to use a computer or other electronic device, including fax machines, to send any
message unless such message clearly contains in a margin at the top or bottom
of each transmitted page or on the first page of the transmission, the date and
time it is sent, an identification of the business or other entity, or other individual
sending the message, and the telephone number of the sending machine or of
such business, other entity, or individual.
(The telephone number provided may not be a 900 number or any other umber for
which charges exceed local or long-distance transmission charges.)
For Canadian Modem Users
NOTICE: The Industry Canada (IC) label identifies certified equipment. This
certification means the equipment meets certain 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. In
some cases, the company’s inside wiring associated with a single-line, individual
service may be extended by means of a certified connector assembly (telephone
extension cord.) The customer should be aware that compliance with the above
conditions may not prevent degradation of service in some situations. Currently,
telecommunication companies do not allow users to connect their equipment to
jacks except in precise situations that are spelled out in tariffing arrangements with
those companies.
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.
For your own protection, make sure 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: Do
NOT attempt to make such connections yourself. Instead, contact
an electric inspection authority or electrician, as appropriate.
