Chapter 1 - Introduction and Description
Chapter 1 - Introduction and Description
Welcome to the world of data communications. You have acquired one of the finest intelligent data and
fax modems available today from one of America’s oldest and most respected modem manufacturers:
Multi-Tech Systems, Inc. This User Guide will help you install, configure, test, and use your modem.
Introduction
The MultiModemDID combines Direct Inward Dial (DID) with Super G3 V.34/33.6K bps fax and V.92 data
modes of operation. Direct Inward Dial allows the user to use a block of telephone numbers larger than
the number of physical telephone lines for direct dialing to extensions. When combining DID with inbound
fax calls to a fax server, each user on the fax server can have faxes automatically routed to them at their
client computer desktop.
DID fax routing assigns a unique fax number for every network user or network device (such as a
printer). Senders simply dial a typical telephone number - no special procedures are required. The fax
server automatically delivers the incoming fax to the user over the local area network.
Users get improved efficiency and security, since their faxes are delivered by the network fax server to
the client desktop as soon as they are received. Time-wasting trips to the fax machine are eliminated and
employees are more productive. In addition, DID offers a higher degree of security for both the sender
and the recipient since faxes are not left unattended at a central fax machine.
The MT5634ZBA-DID utilizes Super G3 V.34 fax speeds of 33.6K bps. Now, computer-based fax servers
can achieve the Super G3 speeds found in dedicated fax machines. The MT5634ZBA-DID also supports
T.31 Annex B and T.32 Annex C, which allows the higher V.34 speeds to operate with Class 1.0 and
Class 2.1 code sets. In addition, “on-the-fly” two-dimensional fax data compression plus support for error
correction mode (ECM) increase the performance of the MT5634ZBA-DID to levels previously only found
in expensive fax boards and dedicated fax machines.
To implement DID fax routing you must purchase fax server application software that supports Multi-Tech
DID commands and DID routing, and obtain an analog DID trunk line which supports the inbound fax
calls and a regular loop-start line for outbound fax transmission.

Chapter 2 - Installation
Step 1: Assemble the Modem
The only assembly required is to mount the feet on the bottom of the modem. Simply peel the four selfadhesive plastic feet off the backing strip and press them into the recesses on the bottom of the modem.
Step 2: Connect the Modem to Your System
Turn off your computer. Place the modem in a convenient location, and then connect it to your
computer’s serial port, the phone line, AC power, DID line, and your phone.
Connect the Modem to Your PC
Plug one end of the serial cable into the connector on the modem, and plug the other end into a
serial port on your computer, such as COM1 or COM2.
Connect the Modem to the Telephone Line
Plug one end of the phone cable into the modem’s LINE jack and the other end into a phone wall
jack. The phone cable is included with your modem.
Note: The LINE jack is not interchangeable with the PHONE jack. Do not plug the phone into the LINE
jack or the line cable into the PHONE jack.
7
MultiModemDID User Guide
Chapter 2 - Installation
(Optional) Connect the Modem to the Phone
For voice-only calls, plug a phone into the modem’s PHONE jack.
Connect the Modem to the AC Power Outlet
Make sure the power is switch is OFF. Plug the DC power transformer into a power outlet or power
strip. Plug the other end into the PWR jack on the modem. The DC power transformer is included
with your modem.
CAUTION: Use only the DC power transformer supplied with the modem. Use of any other
transformer voids the warranty and can damage the modem.
Connect the Modem to the DID Line
Plug one end of the phone cable into the modem’s DID jack and the other end into an analog DID
trunk line jack. The DID Line cable is included with your modem.
CAUTION: The DID Line cable has a 4-pos RJ11 on one side and a 6-pos on the other. Never plug
the DID connector into a standard POTS Line. This may damage the modem or the central office
equipment. Use only an analog DID Line.
Power-on Test
Test the modem by turning it on (an on-off switch is located on the side panel). When you apply
power, the modem performs a diagnostic self-test. The 56 indicator lights, and if a terminal program
is running, the TR indicator also lights. If this does not happen, check that the power switch is on,
the power supply is solidly connected, and the AC outlet is live. If these measures do not work, see
the Troubleshooting chapter.
Step 3: Install the Modem Driver
1. Make sure your modem is connected properly, and then turn on your computer. Windows should
detect your new modem and open the Install New Modem wizard.
Note: If Windows cannot find a modem, your modem may be turned off, it may be plugged into the
wrong connector on your computer, or the serial cable may be faulty. See “None of the LEDs Light
When the Modem Is Turned On” and “The Modem Does Not Respond to Commands” in the
“Troubleshooting” chapter in the complete User Guide.
2. Insert the MT5634ZBA-DID CD into your CD-ROM drive, and then click OK.
3. Windows installs the modem driver.
4. Click Finish to exit
Removing Your Old Modem from Windows
When your new modem replaces another modem, the old modem installation remains in Windows after
you install the new modem, and the old modem is still selected in HyperTerminal and other Windows
applications. Although you can change the application connection descriptions one at a time, it is easier
to force Windows applications to use the new modem by removing the old modem from Windows.

Chapter 3 - Operation
DID Operation
Direct Inward Dialing (DID) uses an analog trunk line to route several phone numbers to one line. The
MT5634ZBA-DID modem has four ports, an RS232 serial port, two RJ11 ports for connection to a POTS
line and an auxillary phone, and a 4 position RJ12 for connection to the DID analog trunk.
Note: The DID and POTS ports cannot operate simultaneously.
On a DID line the roles of the central office and the DID modem are somewhat reversed. The DID
modem must provide a DC voltage, around 48V, to the line. When there is an incoming call, the central
office will complete a loop and draw current from the DID modem.
On a standard POTS line, the central office provides the DC voltage and the user will close the loop by
lifting the handset of a phone or making a call with a standard modem.
There are two critical points about the DC voltage:
1. The central office is sensitive to the DC polarity. TiP (positive) and riNg (Negative) must be
connected to the line from the central office with the proper polarity. If not, callers will receive an
immediate busy signal or may be allowed to make a short connection but become unexpectedly
disconnected after a short time.
2. The DC voltage should be applied by the modem at all times, even when not in use. Occasionally,
the central office will check the line; and, if a voltage is not sensed, the line will be put out of
service. A call to the phone company will be required to get the line back in service.
The DID modem may use line reversals to signal the central office to send digit information or open the
channel to the calling party depending on the start protocol of the DID line. The central office will forward
several of the last digits of the incoming call to the DID modem through one of three formats, DTMF, MF,
or pulse signaling.
V.92 Operation
Because the V.92 protocol is new and still largely unsupported by central servers, some features are
disabled by default in the initial release of the MT5634ZBA-DID modem. This section describes the status
of the V.92 features in the initial release. Please note that the V.92 special features require connection to
a V.92-capable server.
• General. The V.92 protocol is enabled by default. If the MultiModemZBA-DID detects another
V.92 modem during the handshake phase, they will connect in V.92 mode; otherwise, they will
connect in V.90 mode or the highest mutually acceptable mode. The AT command that controls
this is +MS=.
• Commands. AT commands specific to the V.92 protocol and the new V.44 compression protocol
begin with the plus character (+). These commands are in this manual. Also, the S109 register
has been modified to support V.92.
• PCM Upstream. PCM Upstream is disabled by default. To upload files at speeds above 33.6
kbps, you must enable PCM Upstream using the command +PIG=1. Please note that this requires
connection to a V.92-capable server. Also, please note that since upload speeds are affected by
line conditions, meeting the previous requirements cannot guarantee speeds above 33.6 kbps.
• Quick Connect. Quick Connect, which shortens the handshake time with another V.92 modem, is
disabled by default. To enable it, use the command +PQC=0. Quick Connect speeds connect
times by skipping the line test during the handshake and using the configuration from the last data
connection. Quick Connect works best when line conditions are consistent from call to call. If line
conditions are variable, enabling Quick Connect can actually increase the connect time slightly.
• Modem on Hold (is not available at this time).

MultiModemDID User Guide
Chapter 3 - Operation
Connecting to the Internet
Your Multi-Tech modem is your gateway to the Internet and the World Wide Web. To access the Internet
and Web via your modem, you must establish a dial-up account with an Internet service provider (ISP).
To locate an ISP near you, look in a local directory or computer publication. Your ISP should provide you
with the following information:
• User name (also called user ID)
• Password
• Access number (the number you call to connect to the server)
• Host name and/or domain name
• Domain Name Server (DNS) server address
If, besides the Web, you use the Internet for e-mail and newsgroups, your ISP should also provide you
with the following information:
• E-mail or POP mail address
• POP server address
• Mail or SMTP address
• News or NNT server address
Dial-Up Networking
Before you can connect to the Internet, you must set up a remote-node client program on your computer.
The Windows version is called Dial-Up Networking. Dial-Up Networking establishes your connection to
the ISP’s server, which is the shared computer that manages calls from clients (your computer) to the
Internet. Most, if not all, Windows browsers start Dial-Up Networking automatically when you open them.
For instructions on how to set up Dial-Up Networking, consult your ISP or your operating system’s online
help or printed documentation. Many ISPs include, as part of their service, a program that will install and
configure Dial-Up Networking automatically for you.

Chapter 4 - AT Commands, S-Registers, Result Codes
Chapter 4 - AT Commands, S -Registers,
and Result Codes
AT commands are used to control the operation of your modem. They are so called because each
command must be preceded by the characters AT to get the ATtention of the modem.
AT commands can be issued only when the modem is in command mode or online command mode. The
modem is in command mode whenever it is not connected to another modem. The modem is in data
mode whenever it is connected to another modem and ready to exchange data. Online command mode
is a temporary state in which you can issue commands to the modem while connected to another
modem. To put the modem into online command mode from data mode, you must issue an escape
sequence (+++) followed immediately by the AT characters and the command, e.g., +++ATH to hang up
the modem. To return to data mode from online command mode, you must issue the command ATO.
To send AT commands to the modem you must use a communications program, such as HyperTerminal
or the PhoneTools communications program included with your modem. You can issue commands to the
modem either directly, by typing them in the terminal window of the communications program, or
indirectly, by configuring the operating system or communications program to send the commands
automatically. Fortunately, communications programs make daily operation of modems effortless by
hiding the commands from the user. Most users, therefore, need to use AT commands only when
reconfiguring the modem, e.g., to turn autoanswer on or off.
The format for entering an AT command is ATXn, where X is the command and n is the value for the
command, sometimes called the command parameter. The value is always a number. If the value is zero,
you can omit it from the command; thus, AT&W is equivalent to AT&W0. Most commands have a default
value, which is the value that is set at the factory. The default values are shown in the “AT Commands”
section, which begins on the next page.
You must press ENTER to send the command to the modem. Any time the modem receives a command, it
sends a response known as a result code. The most common result codes are OK, ERROR, and the
CONNECT messages that the modem sends to the computer when it is connecting to another modem.
For a table of valid result codes, see “Result Codes” at the end of this chapter.
You can issue several commands in one line, in what is called a command string. The command string
begins with AT and ends when you press ENTER. Spaces to separate the commands are optional; they
are ignored by the command interpreter. The most familiar command string is the initialization string,
which is used to configure the modem when it is turned on or reset, or when your communications
software calls another modem.

Chapter 4 - AT Commands, S-Registers, Result Codes
DID Commands
The MT5634ZBA-DID modem uses *D commands to configure the modem’s DID features. The modem
must be configured for the proper protocol, digit format, digit time out, digit report format, and number of
digits. This configuration is determined by the company from which the DID line is ordered and the setup
used by the phone company. The DID configuration parameter settings of the modem can be viewed as
part of the report of the AT&V command and can be stored with the AT&W0 command.
MT5634ZBA-DID Initialization Recommendations
Since the MT5634ZBA-DID can be processing a DID call before signaling the DTE, care must be
taken to avoid unexpected call problems.
The first command of an initialization string should probably busy out the DID line. This will allow calls
to rollover to other trunk lines in a trunk system or receive a busy signal in a single-line system. This
will also avoid problems such as missing the incoming DID number information or causing a
character abort of the incoming call after the DID information has been received.
Conversely, the last command to give the modem should be the AT*DS configuration command
putting the modem back in service and ready to receive incoming DID calls.
A check has been put in the AT&F command to determine if the modem has started a DID call. If the
modem has started a DID call, it will respond to an AT&F command with an ERROR response and
not process the AT&F.
The AT*DW command can be used to keep a modem “Off Hook” or busied out at the completion of a
DID call so the modem can be initialized without the concern of corrupting an incoming call.
Commands:
Command: *DS
Values:
Default:
Description:
*DS0
*DS1
*DS2
*DS3
Start Protocol
n = 0, 1, 2 or 3
0
Three DID start protocols: Wink, Immediate, and Delay Dial:
In the Wink Start protocol, the central office closes the loop and
draws current. The modem senses the current draw and will
reverse the DC polarity for a short pulse to signal that it sees
the incoming call and is ready to accept the DID digits.
Delay Dial is the same as Wink Start except that the length of
the reverse pulse is not defined. When the DID modem senses
the current draw, it reverses the DC voltage until it is ready to
receive the DID digits.
On an Immediate Start DID line, the central office closes the
loop for a short time and then sends the DID digits without
waiting for a response from the DID modem.
After the central office sends the DID digits all three lines
operate the same way. The modem will reverse the DC polarity
to signal the beginning of the call and the central office will
open the channel to the caller and begin billing. When the call
is completed, the DID modem will return the DC voltage to
normal polarity and the central office will open the circuit.
While the modem is monitoring the DID line for current draw, it
is also monitoring the POTS line for incoming rings.
Disables DID detection of incoming DID calls (DC voltage still
applies to DID line, but polarity is reversed to busy out line).

Description:
Wait for Digit Time-Out Time
n = 0, 1, 2 or 3
0
This command is used to configure the time between each

proper number of digits when the timer expires, it will report
the digits it has received so far and move on to the answering
sequence described in the *DN command.
Command:
Values:
Default:
Description:
*DN
Number of DID Digits Expected
0-7
0
This command is used to configure the modem for the
expected number of digits from the central office (the central
office will send the last few digits of the called number). When
the proper number of digits are received, the modem will pass
the digit information to the host computer. After passing the
digits the modem will answer the incoming call if S0 is greater
than 0. Otherwise the modem will wait for the host computer to
issue an ATA command.
Command:
Values:
Default:
Description:
*DW Busy-Out Timer at End of Call
0-255
0
This command defines the amount of time to busy out the
modem upon disconnecting from a DID call. The delay is ended
when the timer runs out or a *DS command is received.
*DW0 This command disables the delay. It ends the delay, but it also
places the DID line a busy-out state.
*DW255 This command will extend the delay indefinitely.
About the Busy-Out Features and Functions
A Direct Inward Dial (DID) line can be put in a “Busy Out” state by
reversing the battery polarity the modem supplies to the line. This will
cause a caller to receiver either a busy signal in a single line system or
roll over to the next line in a trunk system.
The line is busied out in the following cases.
- Modem is set to the factory default DID start format *DS0
- Modem receives an incoming ring on the POTS line
- Modem is given the dial command ATD
- Modem is set with the *DW command to busy-out delay after
finishing a call

0
This command allows for three different reporting formats of
the incoming number information. This information is output
when either the proper number of digits have been received or
the time out timer has expired and before the modem answers
the call. When set to *DFI, the modem will output one line for
every digit received. For the other formats, the modem will only
output one line per call.

Chapter 5 - Remote Configuration
Chapter 5 - 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 MT5634ZBA-DID modem for maintenance or troubleshooting as if you were on
site.
Basic Procedure
The following steps are valid regardless of whether the connection is established by the local or the
remote Multi-Tech modem.
1.
Establish a data connection with a remote MT5634ZBA-DID modem.
2.
Send three remote configuration escape characters followed by AT and the setup password, and
press ENTER. Example: %%%ATMTSMODEM. You have four tries to enter the correct password
before being disconnected. If the password is correct, the remote modem responds with OK.
3.
You can now send AT commands to configure the remote modem.
4.
When you have finished configuring the remote modem, save the new configuration by typing
AT&W0, and pressing Enter.
5.
Type ATO and press Enter to exit remote configuration. You can then break the connection in the
normal way.
CAUTION: If you hang up while you are in remote configuration mode, it may lock up the remote modem.
Setup
Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who
has an owner’s manual knows the default setup password, for security you should change the password
and possibly also the remote configuration escape character.
Changing the Setup Password
1. Open a data communications program such as Phone Tools or HyperTerminal.
2. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the
MTSMODEM password with xxxxxxxx) 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=xxxxxxxx, where xxxxxxxx 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 can now either 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.

MultiModemDID User Guide
Chapter 5 - Remote Configuration
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!
1.
Establish a remote configuration link with the remote modem as described in “Basic Procedure.”
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 6 - Troubleshooting
Chapter 6 - Troubleshooting
Your modem 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. The following symptoms are typical of problems you might encounter:
•
None of the LEDs light when the modem is on.
•
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.
•
The modem doesn’t work with Caller ID.
•
Fax and data software can’t run at the same time.
If you experience problems, please check the following possibilities before calling Technical Support (see
Appendix E).
None of the Indicators Light
When you plug in the modem, the Power LED should come on. After the operating system detects and
configures the modem, the TR LED should come on.
•
If the Power LED does not come on, double check the cable connections.
•
If the TR LED does not come on, check to see that the software from the installation disk has
been installed (see Chapter 2, Step 3).
The Modem Does Not Respond to Commands
•
Make sure you are issuing the modem commands from the data communications software, either manually in terminal mode or automatically by configuring the software. (You cannot send
commands to the modem from the DOS prompt.)
•
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 and the problem likely is in
the connect setup in your communications software.
•
Try resetting your modem by unplugging the DID cable from the modem, and then plugging it
back in.
•
Try rebooting the computer.
•
The modem might be defective. If you have another Multi-Tech modem, try swapping modems. If
the problem goes away, the first modem is possibly defective. Call Tech Support for assistance
(see Appendix E).

Chapter 6 - Troubleshooting
The Modem Dials But Cannot Connect
There can be several reasons the ZBA fails to make a connection. Possibilities 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.
You can narrow the list of possibilities by using extended result codes. Extended result codes are enabled by default. If they have been disabled, enter ATV1X4 and press ENTER while in terminal mode, or
include V1X4 in the modem’s initialization string. When you dial again, the modem will report 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 might 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 might 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 might not recognize the dial tone and might 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 replace X4 with X3, which will cause the modem to
ignore dial tones (note, however, that X3 is not allowed in some countries, such as France and
Spain).
•
If the modem reports BUSY, the other number might be busy, in which case you should try
again later, or it might indicate that you have failed to add a 9, prefix to the phone number if you
must dial 9 for an outside line.
If you must dial 9 to get an outside line, the easiest way to dial it automatically is to include it in
the modem’s dial prefix, e.g., ATDT9,. Note the comma, which inserts a pause before the number is dialed. By inserting 9, into the dial prefix, you do not have to include it in each directory
entry.
To change the dial prefix in Windows 98 HyperTerminal, select Call from the Call menu, click
Dialing Properties, and type 9 in the local and long distance boxes in How I dial from this location.
•
If the modem reports NO ANSWER, the other system has failed to go off-hook, or you might
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 might have dialed a wrong number, and a person answered instead of a
computer, or you might 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, and the modems might be having problems
negotiating because of modem incompatibilities or line noise. Try connecting at a lower speed.

Chapter 6 - Troubleshooting
The Modem Disconnects While Online
•
If you have Call Waiting on the same phone line as your modem, it can 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 automatically disable Call Waiting by including the disabling code in the modem’s dial
prefix (e.g., ATDT*70,—note the comma, which inserts a pause before the number is dialed). To
change the dial prefix in Windows 98 HyperTerminal, select Call from the Call menu, click Dialing Properties, check This location has Call Waiting, and select the correct code for your
phone service.
•
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 especially for the modem.
•
Check for loose connections between the modem and the computer and the telephone jack.
•
You might have had a poor connection because of line conditions or the problem might have
originated on the other end of the line. Try again.
•
If you were online with an online service, it might have hung up on you 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
•
Autoanswer might be disabled. Turn on autoanswer in your data communications program or
send the command ATS0=1 (ATS0=2 if you have Caller ID service) to make sure your modem
in terminal mode.
The Modem Doesn’t Work with Caller ID
•
Caller ID information is transmitted between the first and second rings, so if autoanswer is turned
off (S0=0) or if the modem is set to answer after only one ring (S0=1), the modem will not receive
Caller ID information. Check your initialization string, and if necessary change it to set the modem to answer after the second ring (S0=2).
•
Make sure that you have Caller ID service from your telephone company.
Fax and Data Software Can’t Run at the Same Time
•
Communications devices can be accessed by only one application at a time. In Windows 98, you
can have data and fax communication applications open at the same time, but they cannot use
the same modem at the same time.

Chapter 6 - Troubleshooting
DID Troubleshooting
•
Make sure that the MT5634ZBA-DID parameters match the DID line. Refer to the *D command.
Also, verify that your fax software is configured to match the analog DID trunk line and the
MT5634ZBA-DID parameters.
•
If callers are receiving an immediate busy signal or are allowed a short connection but become
unexplectedly disconnected after a short time, try reversing the TIP and RING wires. The central
office is sensitive to the DC polarity and this will reverse the polarity.
•
If the MT5634ZBA-DID line is out of service, verify that the DC voltage is being applied by the
MT5634ZBA-DID to the DID line. This voltage should be applied to the line at all times, even
when the PC is not in use. The central office will check the line occasionally and if a voltage is
not sensed, the line may be put out of service. If this has occurred, call the phone company to get
the line back in service. Be sure to have you DID line information available.
•
Note that the DID and POTS ports on the MT5634ZBA-DID cannot operate simultaneously. You
can use only one port at a time since they share common circuitry within the modem.
•
If the MT5634ZBA-DID is totally inoperational, verify that the power supply shipped with modem
is connected properly to the modem and the wall outlet.
Important: Use the power source shipped with your modem. If you use any other power source,
you could damage the MT5634ZBA-DID and void the warranty.

Appendix D – Upgrading the Modem’s Firmware
MultiModemDID User Guide
Appendix D - Upgrading the Modem’s
Firmware
Upgrade Overview
1.
Identify your modem’s model number and firmware version.
2.
Identify the current version of the firmware at the Multi-Tech Web site. If your modem already has
current firmware, there is no need to install it.
3.
Download the upgrade file and the appropriate Flash Wizard for your modem.
4.
Install the Flash Wizard and extract the firmware .HEX file from you the file you downloaded.
4.
If the firmware version number matches the firmware version number found in “Step 1: Identify
the Modem Firmware,” you have the current firmware version and do not need to be update.
5.
Document and clear your stored parameters.
6.
Upgrade the firmware using the .HEX file and the Flash Wizard.
7.
Restore your parameters.
.
Step 1: Identify Your Modem‘s Number and Firmware
You must know the model number and firmware version of your Mult-Tech modem to know whether
or not you should update it.
1.
Run your favorite terminal program. If you are using Windows 95 or above, you can use
Windows Hyperterminal.
2.
In the program’s terminal window, type AT&F. Even if you cannot see the AT&F command on
your screen, be sure to type it completely, and then press Enter. If the modem does not respond
with OK, repeat the AT&F command.
3.
Now type ATI, press Enter. The model number and firware version should appear. Record these
results.
Step 2: Indentify the Current Firware Version
1.
Using your favorite Web browser, go to http://www.multitech.com/support/MultiModemZBA/
firmware.asp
2.
Scroll down to your modem model number.
3.
Look at the firmware version number for your modem.
4.
If the firmware version number matches the firmware version number found in Step 1, you have
the current firmware version and do not need to update.
5.
If the firmware version is greater than the one found in Step 1, your modem has an older version
of firmware. Continue with Step 6.
Warning: The first digit of the new firmware must match the first digit of the old firmware or the
modem may not work properly. If your current version is 4.16, replace it only with 4.xx, not 6.xx.
Step 3: Download the Upgrade File
1.
If you are not already at the MultiModemZBA Firmware page of the Multi-Tech Web site, follow
the procedure in “Step 2: Identify the Current Firmware.”
2.
Download the upgrade file for your modem by clicking its name, and save the file in a temporary
folder on your hard disk.
3.
In the same section of the Web page, click the Flash Wizard utility for your operating system to
download it, and save it in the same folder.
52
MultiModemDID User Guide
Appendix D – Upgrading the Modem’s Firmware
Step 4: Extract the Upgrade Files
1.
Install the Flash Wizard utility by double-clicking the file name in Windows Explorer.
2.
Extract the upgrade files by double-clicking the file name. The extracted files include a .HEX file,
which contains the upgrade data, and a Readme file.
3.
Copy the upgrade .HEX file into the Flash Wizard folder, which, in a default installation, is at
C:\Program Files\MultiTech Systems\Flash Wizard\.
Step 5: Clear Your Stored Parameters
Before you flash your modem, you should record the parameters that are currently stored in it, so you
can reprogram it after flashing. After you have recorded them, send the AT&W1Z command to the
modem to clear the stored parameters.
1.
Run your favorite terminal program. If you are using Windows 95 or above, you can use
Windows HyperTerminal.
2.
In the program’s terminal window, type AT&V and press ENTER to list your modem’s current
parameters.
3.
Record your parameters by saving the screens and sending them to your printer.
4.
Type AT&W1Z and press ENTER to clear your stored parameters and reset your modem to
factory default.
5.
Close the terminal program.
Step 6: Upgrade the Modem’s Firmware
Before you begin the following procedure, read the README.TXT file extracted from the upgrade archive
file. Note the file name for the new firmware (example: ARQG125A.HEX).
Warning: Never install an older version of firmware over a newer version. Doing this WILL DESTROY
THE FLASH PROM! If the flash PROM is destroyed, the modem must be sent in for repair.
1.
Run Flash Wizard by double-clicking its icon or file name, or by selecting it from the Start menu.
The Identifying Devices dialog box is displayed as Flash Wizard locates and identifies the
devices connected to your system.
Note: If the message ERROR: No valid devices detected is displayed, verify that the modem is
turned on and that all cables are correctly and securely attached.
2.
Click the modem to be upgraded, and then click Next to proceed.
3.
Select the port to be upgraded from the Port list, select the appropriate .HEX file from the Hex
File list, and then click Next to continue.
Note: Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.
4.
The Progress dialog box appears, showing a status bar that indicates the progress of the upgrade.
Caution: Any disruption of the program during this stage of the upgrade can cause your modem
to become inoperable. Wait for the Next button to become active before proceeding.
5.
When the flash upgrade is complete, the message Programming Complete appears. Click Next
to continue.
6.
The Results dialog box appears next. Click Finish to exit Flash Wizard.
Step 7: Restore Your Parameters
Your modem has been updated. You can now open your terminal program to reprogram your modem parameters or to confirm the update by typing ATI in the terminal window and pressing ENTER.

Appendix E – Installng a Modem Under Linux
Appendix E - Installing a Modem Under
Linux
Introduction
This appendix explains how to install a modem on a computer operating under the Red Hat Linux 6.2 operating system. Other versions of Red Hat and other Linux operating systems should be similar. Briefly,
in Linux, you do not need drivers for most standard external modems and most internal ISA bus modems.
Programs in Linux commonly call upon the port, rather than the modem.
Standard Linux Serial Port Definitions
PC port Linux port
Com1 ttyS0
Com2 ttyS1
Com3 ttyS2
Com4 ttyS3
Installation
Connect the external modem to an available serial port.
Setup
This section describes how to make sure Linux can talk to the modem and be able to dial up to the Internet. Linux can use different programs and desktops depending on who made the Linux operating system
and what version it is. The following procedures use the most commonly installed components of Red Hat
6.2. More information can be found in your Linux OS owner’s manual.
Using the Terminal Program Minicom to Verify Operation
1.
2.
3.
4.
5.
At the command prompt, type minicom –s and press ENTER.
Select Serial port setup and press ENTER.
From Serial port setup, use the A key to access Serial Device, and then press ENTER.
Press ESC.
You are now in the Minicom terminal. Type AT and press ENTER. The screen should display OK to
verify the operation. Alternately, dial a phone number to verify line operation
6. To leave Minicom, press CTRL + A, and then press Z.
7. On the help menu, press X to exit.
Using the Modem to Call the Internet
Linux allows different graphic user interfaces (GUI). In the following steps, we’ll use the Gnome Desktop
GUI and assume that the Internet Service Provider (ISP) you are calling assigns you the Domain Name
Service (DNS) and Internet Protocol (IP) addresses. For more information on DNS or IP, see the Linux
OS owner’s manual or contact your ISP.
1.
On the Task Bar at the bottom of the screen, select the Gnome Footprint.
2.
Select Internet from the menu.
3.
Select Dialup Configuration Tool.
4.
Select Add, and then click Next.
5.
Enter the connection name and phone number, and then click Next.
6.
Enter your user name and password, and then click Next.
7.
Select Normal ISP if your ISP is not listed, and then click Next.
8.
Click Finish.
54
MultiModemDID User Guide
Appendix E – Installng a Modem Under Linux
Calling the ISP
1.

Answering Calls
To use the system for answering calls, Linux requires other programs to be installed, such as Mgetty,
Mgetty+Sendfax, and others, depending on your requirements. Each vendor of Linux has more than
adequate information on installing these programs.
