data/fax/voice modems available todaythe MultiModemZPX-PCI
from Multi-Tech Systems.

The MultiModemZPX-PCI is an internal, half-length, fax modem card
that can be plugged into any PCI slot. Your MultiModemZDX-PCI
incorporates V.90/K56flex
Internet connections at data rates up to 56 Kbps over standard
telephone lines. V.90/K56flex technology is able to propel data
downstream from the Internet to your computer at speeds of up to 56
Kbps because data is digitally encoded instead of modulated. Upstream
transmission, mostly keystroke and mouse commands from your
computer to the central site, continues to flow at the conventional data
rate of 33.6 Kbps.

Note: Though this modem is capable of 56 Kbps download
performance, line impairments, public telephone infrastructure, and
other external technological factors currently prevent maximum
56 Kbps connections.

Your MultiModemZPX-PCI offers interactive automatic dialing, as
well as command mode option configuration. You can store two
command line/telephone numbers, of up to 40 characters each, in the
modems nonvolatile memory. The modem pulse or tone dials and
recognizes dial tones and busy signals for reliable call-progress
detection. The modem can detect AT&T calling card tones. It is FCC­Registered for connection to telephone networks without any Data
Access Arrangements (DAAs).

1 Introduction and Description

V.90 Support/Functions

V.90 is the ITU designation for what formerly was called V.pcm. V.90
replaces K56flex and other proprietary solutions for PCM connections.
Dual-mode client modem code will be important until all central-site
digital modems are upgraded to V.90 and all interoperability problems
are resolved. Until that time, the Dual-mode client code provides
reliable connections in K56flex mode to the central-site modems
currently deployed. V.90 functions/features include:

 V.90/K56flex A-law and µ-law support

 New downstream data rates (S-Register S38)

 Optional V.8bis sequence

 V.90 Mode Selection (S-Register S109) support

 Auto-rate speeds to 50,666 (downstream) support

 Automatic adapting to digital loss and robbed-bit signaling

 New V.90 rate result codes

Downstream Rates

Where K56flex provided rates of 32,000 to 56,000 in 2,000 bps
increments, V.90 provides rates of 28,000 to 56,000 bps in increments
of 1,333 bps.

Upstream Data Rates

Upstream V.90 data rates are 4800 to 33600 bps in 2400 bps
increments.

Optional V.8bis Sequence

The V.8bis sequence that precedes K56flex connections is optional for
V.90. Dual-mode servers indicate this capability using V.8bis. Dual­mode clients complete the V.8bis exchange and then proceed to either
the K56flex mode or V.90 mode. V.90-only clients can skip the V.8bis
exchange as a way to shorten the startup time.

Auto-rate Speeds

Auto-rate speeds to 50,666 Kbps are supported for downstream
transfers.

Figure 2-1. MultiModemZPX-PCI

MT5634ZPX-PCI 15

Owner’s Manual

Configuring the MultiModem ZPX-PCI

Windows 95 Plug and Play

Unlike an external modem, the MultiModemZPX-PCI contains its own
serial port. When Windows 95 detects the MultiModemZPX-PCI, it
assigns the next available COM port number to it. Since COM1
through COM4 are standard serial ports in Windows computers,
Windows 95 typically assigns COM5 to the modems serial port.
Windows 95 also assigns the a port address and interrupt request (IRQ)
number. Because the number of IRQs is limited, a computer with
several accessories may not have an available IRQ for your new
modem. In that case, you may have to decide which of your other
accessories you can modify or do without.

Sound Card Considerations

If you want speakerphone functions and the ability to record sound or
.WAV files through the sound card at the same time, you need:

 Two stereo PC microphones
 One stereo male-to-male patch cord
 One sound card and optional speakers

To connect a third party sound card:

1. Obtain a stereo male-to-male patch cord (can be purchased at a
local PC retail store).

2. Place one end of a stereo male-to-male patch cord into the LINE
OUT jack of the MultiModemZPX-PCI and the other end into the
LINE IN jack of the sound card. This allows you to hear the
activity of the modem whether it is originating or answering a call
or playing a recorded message using the bundled Trio software.

3. Place the stereo microphones (do not use mono microphones) far
enough apart from each other to eliminate feedback (e.g., one on
each side of the monitor). Feedback occurs if the microphones are
too close to each other. Make sure speakers are amplified with
power source being either a battery or AC outlet.

4. Place microphone and speakers far enough apart from each other
to eliminate feedback. Plug connector of both microphones into
the MIC IN jack of the SoundCard and the MultiModemZPX-PCI.

your new modem and asks you to confirm the selection.

Is Your MultiModemZPX-PCI Ready for Use?

If youre an experienced modem user, you may want only to check
your modems settings for data compression, error correction, and so
on. You may find you can get moving quite quickly if you just issue
the AT&V<cr> command. This command lists how your modem
currently is configured, the stored (user) profiles, and the first four
stored telephone numbers. If you come across a setting youre unsure
of, refer to Chapter 3 of this manual for AT command and S-register
explanations and defaults.

If youre a novice, please continue to the next sections of this chapter.

MT5634ZPX-PCI 21

Owner’s Manual

Operating Your MultiModemZPX-PCI

You control your MultiModemZPX-PCI by issuing AT commands and
setting S-registers. Since your MultiModemZPX-PCI is set up for
typical user applicationtraditional modem set to make a dial-up call
to a remote installation where the call is answered automaticallyyou
shouldnt need to change the current default configuration. (If you
know your application does not follow this profile, refer to Chapter 3
for AT commands and S-registers.)

In operating your MultiModemZPX-PCI, it is likely that you will use
your data communications software to either:

 Enter terminal mode, where you can speak most directly to the

modem by issuing AT commands, or

 Launch a data communications session through a set of modem

configurations that you select and then associate with a target
telephone number. Once you create, save, and name this set of
information according to your connection needs and your datacomm
softwares conventions, the software simplifies dialing because you
dont have to reconfigure the modem nor have the risk of typing
incorrect information.

Either way, be aware that an AT command is the method by which
your modem is controlled and must therefore prefix nearly all
commands. AT stands for attention and alerts the modem that a
command follows. You can enter AT commands with uppercase or
lowercase characters. Once youre in terminal mode, enter AT
followed by <cr> to check whether your modem is operational. If
everything is fine, your modem responds OK.

Simple Operation

You can dial by using the ATD command and the phone number of the
modem you want to connect with, e.g., ATD6127853500. Your
modem dials the number and makes a scrambling noise as the modem
negotiates the kind of connection it can make. Once the modems settle
on a common connection, a connect message on your computers video
displays. To hang up, enter +++ATH0<cr>. The modem hangs up and
your video displays OK, signifying it is ready for another command.

2 Installation

Software Configuration

Communications software must be configured to work with the
MultiModemZPX-PCI, your computer, and the remote system it is
calling. Fortunately, most communications programs make the process
easy by providing a default initialization string to your modem as well
as defaults for most of the other required parameters. Some software
programs allow you to select your modem type from a menu. With this
method, initialization strings that correspond to a particular modem
type can be selected to operate optimally with the software the modem
is using.

Note: Refer to your respective software manuals for further
information on your communications software.

Other software programs require you to enter an initialization string in
the software modem setup screen. If this is the requirement in your
software application, enter the following command string to initialize
your modem: AT&F<cr>. This setting configures your modem to
operate with defaults set at the facotry. These settings work well with
most software packages.

Testing Data Functions

You can test the MultiModemZPX-PCIs data functions by using
HyperTerminal to call the Multi-Tech Bulletin Board System (BBS)
and to download a file.

1. Select Start, Programs, Accessories, and then HyperTerminal.

2. Start HyperTerminal by double-clicking the Hypertrm icon.
HyperTerminal asks for the name of the connection.

3. Type Multi-Tech BBS in the Name text box and click OK.

4. In North America, type 800 in the Area Code box and 392-2432
in the Phone Number box. Local and international users, type 612
in the Area Code box and 785-3702 in the Phone Number box.

Testing Voice Function

There are several tests you can perform to verify the MultiModemZPX­PCIs voice circuits. Try the answering machine test first. If that
doesnt work and you have a microphone and speaker connected to the
MultiModemZPX-PCI, try the loopback and speakerphone tests, which
can test the modems voice circuits without special software.

MultiModemZPX-PCI’s Answering Machine Test

Test the MultiModemZPX-PCIs voice function by using the included
software to set up the MultiModemZPX-PCI as a telephone answering
machine. Have a friend call and leave a message; then play it back.

Loopback Testing

1. Connect a microphone and speaker to the MultiModemZPX-PCI.
To avoid feedback, make sure the microphone and speaker are not
placed too close to each other. For best results, use a headphone
instead of a speaker. If using a headphone, be sure to reduce the

Configuring Communications Software

Communications software must be customized, or configured, to make
it work with your computers serial port and modem, to meet the
requirements of the system on the other end of a connection, and to
meet your own requirements.

Windows 95 makes configuration easy for Windows 95 compliant
communications software. The modem and port, for the most part, are
configured automatically when the modems drivers are installed in
Windows. The communications software then uses the Windows 95
supplied configuration when it dials out.

However, nonPnP systems as well as legacy programsthose designed
for earlier operating systems(nonPnP)must be configured
individually.

This chapter helps you make configuration choices specific to the
MultiModemZPX-PCI. For help with other configuration choices, refer
to the softwares manual or online Help. Generally, your best course is
to accept the softwares default values.

1. Turn on your computer and run your communications software.

2. Locate the dialog box or menu that allows you to specify your
modem.

 In HyperTerminal, select File, Properties, and then Phone

Number.

 In ProComm Plus for Windows, select Window, Setup, and

then Advanced.

 In MultiExpress Terminal for Windows, select Setup,

Terminal, and then Modem.)

3. If you are using legacy software or if you have more than one
modem installed, choose the appropriate model number for the
modem (e.g., Multi-Tech MT5634ZPX-PCI) from the softwares
modem list. If your model number isnt listed, choose a generic
modem of the same speed as yours, e.g., a generic V.34 or 33600
bps modem and rename it Multi-Tech MT5634ZPX-PCI.

28 MT5634ZPX-PCI

2 Installation

4. If your legacy software doesnt have the correct modem

initialization string, you must change it. AT&F^M, which selects
the modems factory default settings, works well for most
connections. (^M is the code for the carriage return character that
sends the string to the modem.)
If you need extra time to make a connection, add S7=60 to the
string like this: AT&FS7=60^M.

For CompuServe, the initialization string is AT&F\N0^M. If you
use CompuServes WinCIM software, change the initialization
string to AT&F\N0\Q1^M for compatibility with WinCIMs
software flow control. Change the error correction string to
\N7%C0 and the data compression string to \N7%C1. If you want
the modem to always answer the phone, add S0=1 to the
initialization string.

Note: To change the modems default initialization string, type
the new commands in the softwares terminal window, adding the
command &W to store the new commands in the modems
nonvolatile memory, e.g., AT&FS0=1&W. You then can simplify
your initialization string to ATZ^M.

5. If you are using legacy software, select the port where the modem
is connected (normally, COM5).

6. For maximum throughput when using data compression, set the
serial port baud rate, or DTE rate, to 115,200 bps. (In Windows
95, select Start, Settings, Control Panel, Modems, and then
Properties.)

7. If your legacy sopftware has an autobaud selection, make sure it is
disabled. Autobaud is for older modems and can cause problems if
enabled.

8. If the software allows you to edit the no-connect messages (NO
CARRIER, BUSY, NO ANSWER, NO DIALTONE), make
sure there is no space between DIAL and TONE in NO
DIALTONE.

MT5634ZPX-PCI 29

Owner’s Manual

9. If you are required to dial 9 to get an outside line, edit the dialing

prefix to include a 9 and a comma, e.g., ATDT9, (the comma
inserts a pause before dialing the next digit).

Similarly, to turn off call waiting for the duration of the call, insert
the disabling code used in your area, e.g., ATDT*70,. If you are
using Windows 95-compliant software, make these changes in the
How I dial from this location box of Dialing Properties.

Note: *70 is used only in the United States.

Remote Configuration

Remote configuration is a network management tool that allows you to
configure modems anywhere in your network from one location. With
password-protected remote configuration, you can issue AT commands
to a remote MT5634ZPX-PCI modem for maintenance or
troubleshooting as if you were on-site.

Basic Procedure

Use these steps for connections established by the local or by the
remoteMulti-Tech modem.

1. Establish a data connection with a remote MT5634ZPX-PCI
modem.

2. Send three remote configuration escape characters followed by

AT and the setup password. Then press ENTER. Example:
%%%ATMTSMODEM<cr>. You have four attempts to enter

the password correctly before being disconnected. If the password
is correct, the remote modem responds with OK.

3. You now can send AT commands to configure the remote modem.

4. When you finish configuring the remote modem, save the new
configuration by typing AT&W0<cr>. Then type ATO<cr> to
exit remote configuration. You can then break the connection in
the normal way.

CAUTION: Hanging up while you are in remote configuration
mode can lock up the remote modem.

30 MT5634ZPX-PCI

2 Installation

Setup

Multi-Tech modems are shipped with a default setup password
(MTSMODEM). For security measures,you should change the
password and possibly also the remote configuration escape character.

New password: __________________________________________

New remote configuration escape character: ___________________

Changing the Setup Password

1. Open a data communications program such as HyperTerminal.

2. In the terminal window, type AT#SMTSMODEM (or
AT#Syyyyyy if you have replaced the MTSMODEM password
with yyyyyy) and press ENTER. The modem responds with OK if
the setup password is correct and ERROR if it is wrong.

3. To change the password, type AT#S=yyyyyy, where yyyyyy
stands for the password, and press ENTER. The password can
include any keyboard character and must be one to eight
characters long. The modem responds with OK.

4. The new password is saved automatically. You now can enter
more AT commands or exit the data communications program.
The next time you remotely configure the modem you must use the
new setup password.

Note: You can only change the setup password locally; you cannot do
it remotely. Also, passwords are case sensitive. The next time you
enter the password, it must be in the same case as you set it up.

Changing the Remote Escape Character

To increase security, you can change a remote modems remote
configuration escape character. The remote configuration escape
character is stored in register S9. The factory default is 37, which is the
ASCII code for the percent character (%). Setting S9 to 0 (zero)
disables remote configuration entirelybut if you do this remotely,
you wont be able to change it back remotely!

MT5634ZPX-PCI 31

Owner’s Manual

1. Establish a remote configuration link with the remote modem as
described in Basic Procedure on the previous page.

2. Type ATS9=n, where n is the ASCII code for the new remote
configuration escape character. Then press ENTER.

3. Save the new value by typing AT&W and pressing ENTER.

4. Type ATO<CR> to exit remote configuration.

Chapter 4—Troubleshooting

Owner’s Manual

Introduction

This chapter covers common problems you may have with your
modem and how to solve them. Your MultiModemZPX-PCI was
thoroughly tested at the factory before it was shipped. If you are unable
to make a successful connection or if you experience data loss or
garbled characters during your connection, it is possible that the
modem is defective. However, it is more likely that the source of your
problem lies elsewhere. Begin with the checklist (below) to make sure
all hardware is connected properly. Then review the common problems
for recommendations on what to change.

Initial Checklist

Always begin with the following checklist to make sure all hardware is
properly connected and that the modem is set up properly.

 Make sure you are running the Microsoft Windows 95 or Windows

98 operating system. This modem will not run properly with other
operating systems.

 Make sure the COM port you chose during setup matches the COM

port set in your communications software. See Chapter 2.

 Check that the phone cord between the modems LINE jack and the

wall jack is undamaged and firmly connected to both.

 If you connected a telephone to your modem, check that the phone

cord between the modems PHONE jack and the telephone is
undamaged and firmly connected to both.

 If you connected a microphone to your modem, check the connection

of the microphone plug to the modems MIC IN jack.

 If you connected speakers to your modem, check the connection of

the speaker plug to the modems LINE OUT jack.

 Retry whatever action was not working.
 If it still does not work, check the following section for a description

and possible solution of your problem.

 If you dont find your problem listed in this chapter, see Chapter 5 to

learn how to reach our technical support technicians via our toll-free
telephone number, the Internet, or CompuServe. Dont forget to fill
out the information in Recording Modem Information in Chapter 5
before contacting a technical support technician.

4 Troubleshooting

Common Problems

You may encounter the following problems:

 The modem does not respond to commands.
 The modem dials but is unable to make a connection.
 The modem disconnects while online.
 The modem cannot connect when answering.
 File transfer appears slower than it should be.
 Data is being lost.
 There are garbage characters on the monitor.
 Fax and communications software wont run at the same time.

If you experience problems, please check the following possibilities
before calling Technical Support (see Chapter 5).

The modem does not respond to commands

 Make sure you are in terminal mode in your data communications

program; then type AT and press ENTER. If you get an OK
response, your connections are good. The problem likely is in the
connection description in your communications software.

 Reset your modem by sending it an ATZ or AT&F command in

terminal mode. If using legacy software (software designed for an
older operating system), make sure the initialization string includes
&F as the first command to cancel any leftover commands that could
interfere with the modems operation.

 If you dont get an OK, the problem may still be in the

communications software. Make sure you have done whatever
necessary in your software to make a port connection. Most legacy
(prior to Windows 95) communications programs connect to the
COM port when the software loads and remain connected until the
program terminates. Some can disconnect without exiting the
program. If this is the case, try issuing the softwares connection
command. Also, if more than one communications program is open,
they can conflict with each other. Make sure all other
communications programs are closed and then try again.

MT5634ZPX-PCI 53

Owner’s Manual

 If using legacy software, the COM port setting may not match the

COM port that Windows 95 assigned. Compare the COM port
setting in your software to the COM port reported in the Diagnostics
tab of the Modems Properties sheet. (Select Start, Settings, Control
Panel, Modems, and then Diagnostics.)

 Another expansion card such as a bus mouse or sound card may be

using the same COM port, memory address, or interrupt request
(IRQ) as your modem. On the Windows 95 desktop, right-click My
Computer and select Properties, Device Manager, and Ports. Then
double-click the port where your modem is connected.

In the ports Properties sheet, click the Resources tab to view the
ports Input/Output range and Interrupt Request. If another device is
using the same address range or IRQ, it appears in the Conflicting
Device List. Resources are assinged at power up by the computers
BIOS. Windows cannot change these resources. If the resources
assigned to the MultiModemZPX-PCI conflict with the resources of
another device, the resources of the second device have to be
changed.

Select the port the conflicting device is on and change it so othe
conflict is resolved. If you need to change switches or jumpers on
the conflicting device, refer to the devices documentation.

 The modem may be defective. If you have another

MultiModemZPX-PCI, try swapping modems. If the problem goes
away, the first modem possibly is defective. Call Technical Support
for assistance (see Chapter 5).

54 MT5634ZPX-PCI

4 Troubleshooting

The modem dials but cannot make a connection

Several reasons why the MultiModemZPX-PCI fails to make a
connection include

 Lack of a physical connection to the telephone line.
 A wrong dial tone.
 A busy signal.
 A wrong number.
 No modem at the other end.
 A faulty modem, computer, or software at the other end.
 Incompatibility between modems.

Narrow the list of possibilities by using extended result codes. If you
disabled the modems extended result codes, enable them by entering
ATV1X4 in the terminal window and pressing ENTER. When you dial
again, the modem reports the calls progress.

 If the modem reports NO DIALTONE, check that the modems

telephone line cable is connected to both the modems LINE jack
(not the PHONE jack) and the telephone wall jack. If the cable looks
secure, try replacing it.

If that doesnt work, the problem may be in your buildings
telephone installation. To test the building installation, plug a
telephone into your modems telephone wall jack and listen for a
dial tone. If you hear a dial tone, your modem may be installed
behind a company phone system (PBX) with an internal dial tone
that sounds different from the normal dial tone. In that case, the
modem may not recognize the dial tone and may treat it as an error.
Check your PBX manual to see if you can change the internal dial
tone. If you cant, change your modems initialization string to
include X3, which makes the modem ignore dial tones.

 If the modem reports BUSY, the other number may be busy. Try

again later. BUSY also may indicate that 9 was not added to the
phone number (if required to dial 9 for an outside line).

If you are required to dial 9 to get an outside line, the easiest way to
dial it automatically using legacy software is to include it in the
modems dial prefix, e.g., ATDT9,. Note the comma. It inserts a
pause before the number is dialed. For example, to change the dial

MT5634ZPX-PCI 55

Owner’s Manual

prefix in MultiExpress Terminal, select Setup and Modem. Then
select the modem type you are using and type the new prefix in the
Dial Prefix box.

To change it for Windows 95 software, select Start, Settings,
Control Panel, and then Modems. In the Modems Properties sheet,
select the appropriate modem model number (e.g., Multi-Tech
MT5634ZPX-PCI), click Dialing Properties and type 9 in the local
and long distance boxes in the How I dial from this location box.

 If the modem reports NO ANSWER, the other system has failed to

answer, or you may have dialed a wrong number. Check the number.

 If the modem reports NO CARRIER, the phone was answered at the

other end, but no connection was made, you may have dialed a
wrong number, and a person answered instead of a computer. Or,
you may have dialed the correct number, but the other computer or
software was turned off or faulty. Check the number and try again or
try calling another system to make sure your modem is working.
Also, try calling the number on your telephone. If you hear harsh
sounds, then another modem is answering the call; the modems may
be having problems negotiating due to modem incompatibilities or
line noise. Try connecting at a lower speed by setting register S37 to
a lower rate (e.g., by typing ATS37=11 in the terminal window and
pressing ENTER) and then calling again.

The modem disconnects while online

 If you have call waiting on the same phone line as your modem, it

may interrupt your connection when someone tries to call you. If you
have call waiting, disable it before each call. In most telephone areas
in North America, you can disable call waiting by preceding the
telephone number with *70 (check with your local telephone
company).

You can disable call waiting automatically by including the disabling
code in the modems dial prefix (e.g., ATDT*70,note the comma,
which inserts a pause before the telephone number is dialed). For
example, to change the dial prefix in MultiExpress Terminal, select
Setup and Modem. Then select the modem type you are using and
type the new prefix in the Dial Prefix box. To change it for Windows

95 software, select Start, Settings, Control Panel, and then Modems.
In the Modems Properties sheet, select Multi-Tech MT5634ZPX-
PCI, click Dialing Properties. Check This location has call waiting
and select the correct code for your phone service.

Note: *70 is used only in the United States.

 If you have extension phones on the same line as your modem, you

or someone else can interrupt the connection by picking up another
phone. If this is a frequent problem, disconnect the extension phones
before using the modem or install another phone line for the modem
only.

 Check for loose connections between the modem and the telephone

jack.

 You may have a poor connection because of line conditions, or the

problem may have originated on the other end of the line. Try again.

 If you were online with a BBS or commercial online service, it may

have hung up because of lack of activity on your part or because you
exceeded your time limit for the day. Try again.

The modem cannot connect when answering

 Auto-answer may be disabled. Turn on auto-answer in your data

communications program or send the command ATS0=1 to your
modem in terminal mode.

File transfer appears slower than it should

 If you are using a slow transfer protocol, such as Xmodem or

Kermit, try Zmodem or Ymodem/G instead.

 Is your line noisy? If there is static on your line, the modem has to

resend many blocks of data to insure accuracy. You must have a
clean line for maximum speed.

 Are you downloading a compressed file with MNP 5 hardware

compression enabled? Since hardware data compression cannot
compress a file already compressed by an archiving program, the
transfer can be marginally slower with data compression enabled
than with it disabled.

MT5634ZPX-PCI 57

Owner’s Manual

Data is being lost

 If you are using data compression, be sure the serial port baud rate is

set to a minimum of four times the data rate.

 Make sure the flow control method you selected in software matches

the method selected in the modem. If you are using CompuServes
WinCIM software, you must set the modem for XON/OFF flow
control (see Chapter 2 for the CompuServe initialization string).

 Try entering the &V (View Parameters) command, making a screen

print of the diagnostics listing, and checking for parameters that may
be unacceptable.

There are garbage characters on the monitor

 Your computer and the remote computer may be set to different

word lengths, stop bits, or parities. If you have connected at 8-N-1,
try changing to 7-E-1, or vice-versa, using your communications
software.

 You may be experiencing line noise. Enable error correction if it is

disabled. Or, hang up and call again; you may get a better
connection.

 At speeds above 2400 bps, the remote modem may not use the same

transmission or error correction standards as your modem. Try
connecting at a slower speed or disabling error correction. (With no
error correction, however, line noise can cause garbage characters.)

 Try entering the &V (View Parameters) command, making a screen

print of the diagnostics listing, and checking for parameters that may
be unacceptable.

Fax and data software won’t run at the same time

 You can have Windows 95 compliant data and fax communication

applications open at the same time, but they cannot use the same
modem at the same time. Make sure no other application is online
when you try to dial out. If you are using legacy communications
software with Windows 95, you may get a message that another
application is occupying the device even when no call is in progress.
Close any open legacy communications programs and try again.

Canadian Limitations Notice

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 of 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 five.

Notice: The Industry Canada label identifies certificated equipment.
This certification means that the equipment meets certain
telecommunications network protective, operational and safety
requirements. 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 may not prevent
degradation of service in some situations.

Repairs to certified equipment should be made by an authorized
Canadian maintenance 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.

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.

Product Safety Compliance

Approved for connection to telecommunications system specified in
the instructions for use subject to the conditions set out in them.

Warning: Interconnection directly, or by way of other apparatus,
of ports marked SAFETY WARNING see instructions for use with
ports marked or not so marked may produce hazardous conditions
on the network. Advice should be obtained from a competent
engineer before such a connection is made.

It is a condition of approval that the power required by the host and the
total of all adapter cards installed within the host environment, together
with any auxiliary apparatus, does not exceed the power specification
as stated in the Technical Reference Material of the host apparatus.

The power requirements for the ZPX are:

Modem operating voltages: +12 VDC, -12 VDC, +5 VDC
Modem power consumption: 1.2 Watts

In order to maintain the independent approval of this card, it is
essential that when other option cards are introduced which use or
generate a hazardous voltage, the minimum creepages and clearances
specified in the following table are maintained. A hazardous voltage is
one which exceeds 42.4 VAC peak or 50 VDC. If you have any doubt,
seek advice from a competent engineer before installing other adapters
into the host equipment.

The equipment must be installed such that with the exception of
connection to the host, clearance and creepage distances shown in the
following table are maintained between the card and any other
assemblies which use or generate a voltage shown in that table. The
larger the distance shown in brackets applies where the local
environment within the host is subject to conductive pollution or dry
nonconductive pollution, which could become conductive due to
condensation. Failure to maintain these minimum distances would
invalidate approval.

72 MT5634ZPX-PCI

Appendix

Figure A-1. Creepage and Clearance Distances.

Except at the edge connector, which plugs into the hosts expansion
slot, clearance distance (Xmm) and creepage distance (Ymm), as given
in the above table, must be maintained between the communication
card and any assemblies which use or generate hazardous voltage.

This apparatus has been approved for the use of the following:

 Auto-calling
 Loop disconnect and MF dialing
 Phone number storage and retrieval by a predetermined code
 Operation in the absence of proceed indication
 Detection of initial and secondary proceed indication
 Automatic storage of last number dialed

Owner’s Manual

European Low Voltage Directive

When correctly installed and maintained, the modem will present no
hazard to the user. When correctly installed the modem will be
connected to the PSTN or a PW and to a Data Terminal Equipment
(DTE), whose modem connections comply with ITU-T
recommendation V.28. The DTE connections are therefore taken to be
safe voltages (less than ± 30 volts).

Ports which are capable of connecting to other apparatus are defined as
SELV. To ensure conformity with EN41003, ensure that these ports
are only connected to ports of the same type on other apparatus.

Protection Against Contact with TNV Circuit (Internal
PC Cards)

The protective cover is fastened to the modem card by means that will
only allow a tool to remove the cover.
Warning: Removal of the protective cover will affect product safety
and user safety requirements.

Appendix D: FLASHWINFlash Upgrade

Introduction

Your modem is controlled by semi-permanent software, called
firmware, that is stored in flash memory. Firmware is nonvolatile; that
is, it remains stored in memory when the modem is turned off.
However, it can be changed by either the manufacturer or the user as
bugs are fixed or new features are added.

Since the firmware in your modem is stored in flash memory, you can
upgrade it yourself in a few minutes by using the following procedures.

FLASHWIN

1. Copy FLASHWIN.ZIP and the downloaded .HEX file to a
temporary directory.

2. After unzipping FLASHWIN.ZIP, run FLASHWIN by double­clicking on its icon or file name.

3. Select the COM port your modem is on and the speed at which
you want to program.

4. Enter the name and path of the *.HEX file you want to load into
the modem.

5. After you verify your selections, click Perform Flash to load the
firmware into the modem.

6. When Loading Status reaches 100%, the modem is upgraded and
you can close FLASHWIN.

Your modem is now updated. You can now open your terminal
program to reprogram your modem parameters, if necessary, or to
confirm the update by typing ATI in the terminal window.
