This device complies with Part 15 of FCC rules. Operation is subject to the following 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 installation. 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 interference 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 encouraged 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.

label that contains, among other information, the FCC Registration Number and the Ringer
Equivalence Number (REN) for this equipment.
IF REQUESTED, THIS INFORMATION MUST BE GIVEN TO THE TELEPHONE
COMPANY.
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 RENs 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 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 possible. You will be informed of

If you experience trouble with this telephone equipment, please contact the Address and Phone
number listed in the warranty card for information on obtaining service or repairs.
The telephone company may ask that you disconnect this equipment from the network until the
problem has been corrected or until you are sure the equipment is not malfunctioning.
The user is not authorized to repair or modify the equipment.
This equipment may not be used on coin service provided by the telephone company.
Connection to party lines is subject to state tariffs.
You will find also this information on a sticker on the bottom of the modems case.

Introduction 1
1 Introduction
Congratulations on the purchase of your Comet 3356P-LAN Type II PCMCIA card,
one of ZyXEL's premier high-performance products. The Comet is world renown for
its ability to maintain ultra high speeds and clear, quality connections while
communicating around the globe.
Unpacking Your Modem
Before you proceed, check all items you received with your modem against this list to
make sure nothing is missing. The complete package should include:
•One Comet 3356 P-LAN
•One detachable interface cable with RJ-11 cable and plug.
•One detachable interface RJ-45 LAN cable and plug.
•One FAX & Data Communication software package.
•One INF file disk for Windows 95 and Windows NT 4.x.
Hardware Overview
The Comet is an intelligent high-speed fax/modem and Ethernet LAN adapter. The
modem can be used as both a send/receive fax machine and a data modem. When
connecting to another modem/fax, the modem automatically negotiates the fastest
speed possible. The PC Card FAX/MODEM/LAN is designed to work with many of
the popular fax/modem and LAN communication software packages. Some software
packages will control and configure the fax/modem for you automatically, however,
they are usually only useful to those who need the modem to perform special tasks. AT
commands can also be used to control the fax/modem manually.
Required Equipment
Make sure you have the additional equipment below before proceeding with
Installation:
•An IBM compatible PC or notebook with PCMCIA type II slot and 386SX or
better CPU.
•PCMCIA Socket Service and Card Service drivers. (These drivers are usually
included with the computer. If not, check with your computer dealer.)
•A telephone line with RJ-11 connector.
•Data and/or Fax communication software.

Basic Modem Operation 13
3 Basic Modem Operation
This chapter covers the basic commands and techniques involved in modem operation.
In many cases, this is the only information you will need in order to get your Comet up
and running with communication software, and to start making connections with your
Comet.
Understanding AT Commands
The Comet communicates asynchronously with computers using AT commands. AT
commands are used to configure and control the Comet. Commands are usually sent to
the modem by way of communication software, but can also be entered manually with
the computer keyboard.
Command statements must be written in a specific form in order for the Comet to
recognize them. A command statement always begins with the letters AT or at. It is
then followed by one or more commands and the <Enter> key.
AT commands can only be issued when the Comet is in “command mode”or “off-
line.”
Once the Comet has established a connection with another modem it is said to be “on-
line”or in “data mode.”In this mode, the characters sent to the Comet by your
computer are transmitted to the remote modem rather than being interpreted by the
Comet as commands.
Using the Windows 95 Hyper Terminal Program
In order to issue an AT command statement, you first need to run a communication
program such as the Microsoft Windows “Hyper Terminal”program. This program
provides a simple method to manually enter AT commands so you can do such things
as “customize”the settings of your Comet, or store phone numbers you will commonly
connect to.
Once the Comet is connected to your computer’s serial port and telephone line, Open
the Windows 95 “Accessories”program group, and open the Hyper Terminal
Program.
The program will prompt you for a name and Icon to use for your new connection.
Type the name Test Connection and press <Enter>.
Next, you will be prompted for country information, area code, and phone number,
and the device used to make the connection. For this test purpose, do not enter a phone
number; simply choose the COM port your Comet is connected to from the “Connect
Using”list. Click “OK”when finished.

14 Basic Modem Operation
The next window sets the COM port settings. The settings used for the Comet should
be as follows:
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow Control: Hardware
Click “OK”when finished. After you have done this, save your new connection by
selecting “Save”from the “File”menu and click “OK.”A new connection icon will be
added to your Hyper Terminal folder.
You are now ready to start entering AT commands.
In the terminal window, type:
AT<Enter>
Comet responds
OK
This confirms that the modem and your computer are communicating correctly.
To test the telephone line connection issue the manual answer command.
Type:
ATA<Enter>
The Comet will pick up the phone line, and try to communicate. Normally, this
command is only used to answer an incoming call made from another modem. Thus
the high pitched noise you will hear from the speaker. To abort the operation, press
any key, or select “Disconnect”from the “Call”menu.
Dialing and Answering Techniques
Depending on what communications software you use to make modem connections,
you may not have as much control of how the modem dials the telephone number. This
section shows some useful examples of the AT commands used for dialing and
answering operations. The command characters specific to each function are shown in
bold type.
