FCC Part 15 Information
This device complies with Part 15 of FCC rules. Operation is subject to the follow-
ing two conditions:
1) This device may not cause harmful interference.
2) This device must accept any interference received, including
interference that may cause undesired operations.
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 installa-
tion.This equipment generates, uses, and can radiate radio frequency energy, and if
not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interfer-
ence will not occur in a particular installation.
If this equipment does cause harmful interference to radio/television reception,
which can be determined by turning the equipment off and on, the user is encour-
aged to try to correct the interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the 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.
Changes or modifications not expressly approved by the party responsible for com-
pliance could void the user's authority to operate the equipment. Shielded RS-232
cables are required to be used to ensure compliance with FCC Part 15, and it is the
responsibility of the user to provide and use shielded RS-232 cables.

The REN is useful to determine the quantity of the devices you may connect to
your telephone line and still have all of those devices ring when your telephone
number is called. In most, but not all areas, the sum of the REN's of all devices
connected to one line should not exceed five (5.0).To be certain of the number of
devices you may connect to your line, as determined by the total RENs, you should

vi
contact your local telephone company to determine the maximum REN for your
calling area.
If your equipment causes harm to the telephone network, the telephone company
may discontinue your service temporarily. If possible, they will notify you in
advance. But if advance notice isn't practical, you will be notified as soon as possi-
ble. You will be informed of your right to file a complaint with the FCC.
Your telephone company may make changes in its facilities, equipment, operations,
or procedures that could affect the proper functioning of your equipment. If they
do, you will be notified in advance to give you an opportunity to maintain uninter-
rupted telephone service.

This certification means that the equipment meets certain telecommunications net-
work protective, operational, and safety requirements. IC does not guarantee that
the equipment will operate to a 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 equip-
ment 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
card).Thecustomer should be aware that the compliance withtheaboveconditions
may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian mainte-
nance facility 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.

should contact the appropriate electrical inspection authority, or electrician, as
appropriate.
The Load Number (LN) assigned to each terminal device denotes the percentage of
the total load to be connected to the telephone loop used by the device without
overloading.The termination on a loop may consist of any combination of devices,
subject only to the requirement that the total of the Load Numbers of all the
devices not exceed 100.
This digital apparatus does not exceed the class B limits for radio noise emissions
from digital apparatus set out in the radio interference regulations of Industry Can-

INTRODUCTION
The2864 series ofV.34 modems includes three sub-series of models, namelytheSu-
preme, Elite and Omni series.The Supreme and Elite series models have ISDN ca-
pabilityorcanbeupgradedtohave ISDN capability.TheOmni series doesnothave
ISDN capability.The Supreme series provides an LCD display panel while the Elite
series has a front panel with LED indicators only. Many features are common to all
threeseries. If not noted otherwise,afeatureillustrated with oneseries model in this
manual applies to the other models and series as well.
The Elite 2864 series of high-speed modems features four base 10models.They dif-
fer only in the implemented line interface module, everything else is equivalent ex-
cept for the panel LED indicator designations.
The models are
The Elite 2864 has a 2-wire dial-up line DAA (Direct Access Arrangement) module
for connection to a normal PSTN (Public SwitchedTelephone Network) 2-wire
dial-up phone line.The Elite 2864L has a DAA with both a dial-up and leased line
interface. A 2 or a 4-wire leased line can also be used besides the normal 2-wire dial-
up line. Dial back-up capability is provided while using leased line.The Elite 2864I
has an ISDN S-interface module that will connect to an ISDN S-interface line. It
will connect to an ISDN call or a modem/fax call from PSTN made to this ISDN
line.AU-interfaceISDNmodule isavailablefortheUSAmarket.TheElite2864IU
is the ISDN model with the U-interface module.
By changing the line interface module, one Elite model will essentially become an-
otherElitemodel. Each Elite model has different markings on its front and rear pan-
els.Thus, in addition to the line interface module the front and rear panel also need
to be changed in order to transform one Elite model into a different Elite model.
Note that each Elite model has its own telecommunication authority approval

Like the Elite series, the Supreme series includes different models which differ only
in the line interface module.There are three models in the Supreme series -The Su-

How To Use This Manual
This manual describes the use of all models in the 2864 series and gives instruction
for their installation and operation.The 2864I and 2864IU ISDN models come
with a separate manual describing their ISDN operation.
The manual is divided into five sections.
Basic Overview - The first section is comprised of chapter 1 (INTRODUCTION)
through chapter 3 (MODEM INSTALLATION). It gives a basic overview of the
2864 series modems' features, introduces some basics of modem operation for nov-
ice users, and explains the installation of the different models of the 2864 series.
Modem Operation-Thesecondsectionintroducesyoutosome skillsyou willneed
tomake the best use of yourmodem.Inchapter 4(MODEMOPERATION)you are
introduced to the use of the different modem ports and you will find information
on how to return the modem to standard settings (reset) and how to upgrade your
modem in the future.The panel operation of the Supreme models is described in
chapter 5 (2864 QUICK START) and chapter 6 (MODEM PARAMETER SET-
TINGS).Usersofthenon-LCDmodelsshouldconsulttheequivalentATcommand
sections listed for each of the panel operations.
Settings and Commands -The third section, chapter 7 (PROFILES) through
chapter 9 (AT COMMAND SET SUMMARY), provides an overview of the settings
and commands which are available in the 2864 series.
Special Functions - Section four is comprised of chapter 10 (ERROR CONTROL
ANDDATACOMPRESSION)through chapter 18(DIAGNOSTICS)anddescribes
manyspecial functions of the 2864 series modems in detail, including data compres-
sion, synchronous and leased-line operation, remote configuration, caller ID, cellu-

lar mode, fax sending and receiving, voice mail, network management, and
diagnostic features.
HintsandTips-Sectionfiveisthetrouble-shootingandspecialadvicesection.Here
you will find additional information on how to use a 2864 series modem with your
computer, and some hints and tipsrelatingtoa number of communication software
applications.
Appendices - An extensive glossary, several appendices with technical details, infor-
mation on standards, and a thorough index complete this manual.
