Introduction

Thank you for purchasing the Actiontec PCI Pro 56K internal modem. The PCI Pro

incorporates the latest technology in controller-less V.90 modems for the PCI bus.

This technology improves the performance and capabilities of personal computer

fax/modems. The use of the PCI Bus frees the user from having to use an ISA slot

which is most likely already being used by another peripheral. Almost every PC has

at least one free PCI slot.

Host-based or “Windows” modems utilize your computer’s internal Central Process-

ing Unit, or CPU to perform some of their functions. The modem’s onboard digital

signal processing circuitry handles the most processor-intensive functions such as

V.90 and V.34 modulation, while the CPU handles more routine communications

tasks like data compression. This allows for fewer parts and greater reliability without

taxing the overall system speed. It also allows the modem greater access to memory

and disk storage space. As personal computers advance in speed and capabilities,

controller-less modems can take advantage of these improvements. Simply download

the new driver, follow the installation instructions, and reboot your system. In this

way, the performance of your modem improves as your PC hardware improves.

Do This First

Please read the following tips carefully before attempting to install your new modem.

For Windows 95 and Windows 98 Installations

Be sure to remove all other modem drivers from your operating system. To do this,

right-click My Computer, choose Properties from the menu that appears, then click

on the Device Manager tab. Double-click the Modems icon in the list of devices to

show the modems installed. Click once on the icon next to any modems in this list to

select them. When all of the modems are selected, click Remove.

Turn off the computer and physically remove your old modem from the system. Once

you remove the old modem and its drivers from your system, you will need the old modem

driver diskette if you wish to reinstall it at a later date.

Restart the computer. On the taskbar, click Start. On the Start menu, click Settings,

then click Control Panel. Double-click on the Modems icon. Select any and all listed

modems and click Remove. Shut down (rather than restart) the computer. Wait 5

seconds before turning it back on.

If you are going to use the Telephone Answering Machine (TAM) functions of the

modem and you are running Windows 95, you need to install a software component

called Unimodem V. If you have Windows 95 OEM Service Release 2 (Version

4.00.950 B, hereafter referred to in this manual as Windows 95B) or a later version

of Windows, this component comes standard as part of the operating system.

To find out which version of Windows 95 you are using, right-click the My Com-

puter icon on the desktop, and choose Properties from the menu that appears. If the

version of Windows 95 is 4.00.950 or 4.00.950A, go to the UNIMODEM directory

of the CD-ROM that came with your modem and right-click on the UNIMODV.INF

icon, (this may be named UNIMODV) then click on Install.. Restart your computer

to enable the drivers.

In order to support older software, the modem will always be assigned to COM 4.

This port assignment is made by Windows based on instructions contained in the

.INF file supplied with the modem. Check Device Manager and verify that COM 4

is not listed.

Right-click on the My Computer icon, choose Properties, and select the Device

Manager tab. From the device tree, double-click the Ports [COM & LPT] icon to

expand the list of ports. COM 1 and COM 2 should be listed. If COM 4 is listed, it

is in use, it must be made available as the modem will be automatically assigned to

this port. Highlight COM 4 by clicking once on its listing in device manager, then

click Remove. Click Refresh. If the COM 4 listing returns, you have a hardware

device using the port. Reinstall the device on another COM port.

For Windows NT 4.0 Installation

Before installing your new modem, be sure to remove any modems and their drivers

from your operating system. On the taskbar, click Start. On the Start menu click

Settings, then click Control Panel. Double-click the Modems icon. Highlight the

modem you wish to remove and click Remove. Turn off the computer and physically

remove the old modem. Do not install your new modem at this time. Follow the

procedures below to help insure a trouble-free installation. Once you remove the old

modem and its drivers from your system, you will need the old modem driver diskette if

you wish to reinstall it at a later date.

Determine that your installation of NT 4.0 is current. Service Pack 3 (or greater),

from Microsoft, should be installed. On the Start menu, click Settings then click

Administrative Tools then click Windows NT Diagnostics. Select the Version folder.

Service Pack 3 (or greater) should be stated. If you do not have the latest service pack

upgrade installed, it must be obtained from Microsoft. The latest upgrade can be

downloaded from the Microsoft web site: www.microsoft.com.

Installing The Modem

Always discharge static electricity before handling your modem. You

may discharge static electricity by touching a grounded metal structure

or by using any commercially available grounding strap.

Make sure the expansion slot type is 16-bit, which has two slots to fit

the ISA card. 8-bit slots have only one connector. If you use an 8-bit

slot, the modem will not have access to the higher interrupts (IRQ 9-

12).

The position of the expansion slots in your computer may differ from

the illustration shown but the installation procedure should be the same.

Hardware Installation

1. Turn off the computer and all peripheral devices connected to it.

2. Unplug the computer power cord from the wall receptacle.

3. Remove the computer’s cover. Refer to your computer owner’s manual for in-

structions.

4. Remove the screw securing the expansion slot cover behind one of the computer’s

available PCI expansion slots. Lift the expansion slot cover out as shown below.

Connecting Devices to the Modem

Figure 4: Connecting Devices

On the rear panel of your modem are input jacks to connect devices to the modem.

As shown in the diagram, there are jacks for connection to a “phone” and to a phone

“line.” The connector labeled Line (Telco) is meant to be connected to a standard

analog phone line. To help reduce the load on your phone line, it is recommended

that the modem be the only device connected. You should remove all other devices

from your telephone line while the modem is in use.

Installing Communications Software

If your modem came with a communications software package, it is strongly recom-

mended that you use this software for your modem. Its default installation param-

eters have been specially configured to work with this modem. The Users Guide for

this program can be found in Adobe Acrobat (PDF) format on the installation CD-

ROM.

Some configurations are packaged without communications software. Check your

packaging to see if communications software is included.

If you wish to use another software package, please be sure that it supports this mo-

dem. Most Software Manufacturers have a listing of supported modems on their

websites or BBSs. Check these sites to see if this model is supported. If you are unsure

or your brand of software supports only a few modems, try selecting “Hayes Com-

patible” or “Standard Modem”. This may work in certain cases.

Some software programs allow manual input of parameters. For the users of these

programs, here is a listing of the Data/Fax/Voice Command Standards supported.

Data:

TIA/EIA-602

Fax:

Voice:

Init String:

TIA/EIA-578 for Class 1 Fax

TIA IS-101 support for TAD (Telephone Answering Device)

AT&F&C1&D2W2

TIA IS-101 Commands not supported:

Caller ID

Full Duplex Speakerphone

VoiceView

Note: some programs must be configured to communicate with the modem on

the same COM port and or IRQ setting used by the modem. See the “In-

stalling the Modem” for instructions on how to determine your COM port

and IRQ settings.

The Modem’s Voice Features

This modem supports TIA IS-101 commands applicable to a Telephone Answering

Device. In order to take advantage of this feature, you will need a Sound Blaster^®

compatible sound card equipped with an external microphone and external speakers.

A software application which supports these TAD functions (such as the one sup-

plied with the modem) is also required.

Download from Www.Somanuals.com. All Manuals Search And Download.

A modem basedTelephone Answering Machine works by using a sound card equipped

with a microphone to record an outgoing message. This message is stored as a .wav

file which is transferred to the modem by the application program when an incoming

call is detected. The modem’s internal electronics converts the digital information

contained in the .wav file into an audio signal which is then sent over the phone line.

The person calling hears your outgoing message and responds with an incoming

message.

The sequence of recording an incoming message is the reverse of an outgoing mes-

sage. The modem converts the audio signal into a digital format and sends it to the

application program. The application program then formats and stores the incoming

message as a .wav file. When you play back your stored messages by selecting them

from within the application program, they are sent to the sound card. You then hear

your recorded messages through the sound card’s speakers.

The default parameters of the software which came with your modem have been

specially configured to identify and use your modems voice capabilities. Even if you

have decided to use another third-party application, try your included application

first. This will allow you to test the modem and its voice functions before investing in

an expensive retail software package.

Troubleshooting

This section lists some common problems and offers suggestions for a solution. It is

important to remember that this modem is a Windows-based modem and requires

32bit virtual device drivers. It therefore cannot work in Windows 3.1 which cannot

use these drivers. The modem also cannot work in DOS regardless of version. It is a

software installed device and has no provisions for manual configuration.

If you cannot find your particular symptom listed here, it is suggested that you re-

move the modem and its drivers from the system and reinstall them again. (See

“Uninstalling the Modem” later in this section.) This provides a “clean” installation

and can cure many temporary problems. See “Do This First” for before reinstalling

the modem.

Most problems encountered during the Windows 95/98/NT installation process are

a result of insufficient system preparation. Make sure to physically remove any previ-

ously installed modems from your system.

If your modem has installed but is not functioning, try the troubleshooting proce-

dure listed below.

Windows 95/95B/98

Step 1: Check System Resources

On the taskbar, click Start. On the Start menu, click Settings, then click Control

Panels, and double-click the System icon. Select the Device Manager tab. From the

device tree, double-click the Modems icon to show what modems are installed. If

there is no Modems icon, your modem did not install (See “Does Not Install”.) If

your modem is listed, check that there is no yellow exclamation mark or red “X” over

the modem’s icon (if there is, go to step 2). If any other modems are listed, highlight

the modem by clicking once on the icon next to the listed modem and then click on

the Remove button. Turn off the system. Wait 5 seconds and turn your computer

back on and repeat step 1.

Step 2: Check Modem Properties

In the Device Manager tab of System Properties, double-click the Modems icon to

show what modems are installed. Highlight your modem by clicking once on the

icon and then click the Properties button. Read the Device Status under the General

tab to see if the device is working properly. Check the Device Usage area and make

sure “Disable in this hardware profile” (Windows 95B and 98 only) or the box la-

beled “Original Configuration, Current” has a check mark (for Windows 95 or 95A.)

Download from Www.Somanuals.com. All Manuals Search And Download.

If either of these conditions are present, correct them. Make a note of the Com port

and IRQ the modem is using. If the Device Status area shows some error message, it

will generally be about a conflict. Go to the Resources tab and read the Conflicting

Device List. If a conflict is present, click to deselect “Use automatic settings” and

select a configuration that does not cause conflicts. Manually change the IRQ set-

tings if needed (see your Windows 95 or 98 on-line help file for a more detailed

discussion on changing these settings). Click the OK button. If there is no setting

free of conflicts, See “Does Not Install.”

Step 3: Modem Diagnostics

On the taskbar, click Start. On the Start menu, click Settings, then click Control

Panel and double-click the Modems icon. Your modem should be listed. If any other

modem is listed, click once on each old modem and then click the Remove button. It

is a good idea to turn off your computer, wait 5 seconds and turn the power back on.

Return to Modems and click the Diagnostics tab. Highlight the modem by clicking

once on the COM port icon next to its listing. Now click the More Info button. You

should see the panel below.

Figure 8: More Info Panel

If you receive an error message or the panel is blank, see “Does Not Install” section.

Download from Www.Somanuals.com. All Manuals Search And Download.

Step 4: Does Not Install

The most likely reason for a non-installation in Windows 95 or 98 is a lack of IRQ

resources. The modem needs one IRQ and two I/O addressees in order to function.

Modern computer systems are usually equipped with sound card, CD-ROM drive,

Hard-drive, floppy drive, video card, two COM Ports, one LPT port, keyboard, and

a mouse. Each of these devices require at least one IRQ (interrupt) in order to func-

tion.

This section deals with the process of freeing IRQ’s and configuring the system for

Plug-N-Play requiring that you know how to enter your computer system’s BIOS

Setup Routine (read your computer user’s manual for information on how to invoke

and use the BIOS setup).

Once inside the BIOS Setup, find the Plug-N-Play configuration. This can be found

within the “Advanced”, “PNP/PCI Configuration”, or “Plug and Play Configura-

tion” section depending on the BIOS Manufacturer. Next, from the information you

noted in Step 2. Find the interrupt selection for the IRQ your modem is using.

(Some BIOSs do not allow individual selection of interrupts to ISA, Plug-N-Play, or

PCI.) You want to set this so that the PCI bus has access to this interrupt. This can be

called ICU/PCI, PCI, or PNP depending on your BIOS version and manufacturer.

Do not set this interrupt to “ISA” only or to “Legacy ISA”.

If you do not have any free interrupts available, you will have to disable some unused

function of your computer system. If you are using a PS/2 style mouse, you may be

able to spare one of your internal COM ports. To disable a COM port, find the

BIOS Setup section for “Integrated Peripherals”. Locate the Serial Port settings and

disable an unused port that has nothing connected to it This will often be serial port

2. This should free one IRQ for your modem to use. You may also have to disable the

COM Port in Windows.

Although it is possible for a PCI card to share interrupts, it is recommended that you

have one free IRQ available in your computer. The modem needs one IRQ and two

I/O Addresses to function. To check for any available interrupts in your system,

right-click on the My Computer icon, choose Properties, and select the Device Man-

ager tab. Click the Properties button to view the System Resources.

Their are 16 (0-15) interrupts available in a system. Make a note of any interrupt not

listed. To make sure that an available interrupt is assigned to the PCI bus, go to your

system BIOS Setup routine and find the Plug-N-Play settings. These are found in the

“Advanced”, “PNP/PCI Configuration”, or “Plug and Play Configuration” sections

depending on the BIOS Manufacturer.

Next, verify that one free IRQ has been set so that the PCI bus has access to it. (Some

Download from Www.Somanuals.com. All Manuals Search And Download.

BIOSs don’t allow individual selection of interrupts for ISA, Plug-N-Play, or PCI.)

The interrupt settings can be called “ICU”, “ICU/PCI”, “PCI”, or “PNP depending

on your BIOS version and manufacturer. Do not set this interrupt to “ISA” only or

to “Legacy ISA”. Be sure to Save the settings before exiting the BIOS Setup.

Under some situations, you will find that freeing an interrupt does not solve your

installation difficulties. This could be due to another peripheral device stealing the

interrupt you just provided. Certain full-featured sound cards require three IRQs to

support all their functions. When one becomes available, they take it. This situation

requires that you remove your sound card, free an interrupt, install the modem and

verify its operation, and then reinstall the sound card. This procedure may also work

for sound cards that have lost their sound after the modem has been installed or if the

modem will not install in a system with a sound card.

Proceed to “Installing the Modem”.

Windows NT 4.0

Windows NT installation problems are always due to inadequate preparation. The

following conditions must be meet before attempting to install the modem or it will

not be seen or correctly installed by the system. (See “Do This First” at the beginning

of this manual.)

•

You must have the latest Windows NT Service Pack installed.

There must be two IRQ and two I/O port Addresses available for the modem to

use.

•

The installation utility must be copied from the installation CD-ROM to the

default hard drive and extracted.

If you need help on freeing an interrupt or making a COM Port available, see the

Windows 95/98 “Does Not Install” section for a discussion of this topic. The “Spe-

cial Situations” and “Plug-N-Play BIOS” sections also apply to Windows NT 4.0.

See these areas for guidelines. If you are upgrading or removing the drivers, use the

installation utility on the Windows NT installation diskette that came with your PCI

modem. This utility has an option for removing the modem drivers.

If you are not familiar with changing the settings within your system BIOS setup,

you should skip the following system pre-installation procedure and go to “Installing

the Modem.” Refer back to this area only if you have a problem installing the mo-

dem.

Check your system BIOS IRQ assignments and make sure that at least two interrupts

have been assigned to the PCI bus. In your system’s BIOS Setup routine, find the

Download from Www.Somanuals.com. All Manuals Search And Download.

Plug-N-Play settings. These settings can be found within the “Advanced,” “PNP/

PCI Configuration,” or “Plug-and-Play Configuration” sections depending on the

BIOS Manufacturer. Next, verify that at least two IRQs have been set so that the PCI

bus has access to them (some BIOS don’t allow individual selection of interrupts to

ISA, Plug-N-Play, or PCI). These settings can be called ICU, ICU/PCI, PCI, or

PNP depending on your BIOS version and manufacturer. Do not set all the inter-

rupts to “ISA” only or to “Legacy ISA”. Pay attention to the IRQ usage of the other

peripherals in your system. Do not reassign an interrupt that is already in use by an

ISA card to the PCI bus.

Common Problems

No Dialtone Error

Make sure you have connected the phone cable into the right connector on the back

of the modem. See Figure 7.

You may have too many devices connected to the phone line. Remove all other equip-

ment.

Your modem may not recognize overseas dialtone. Use the AT command ATX0to

have the modem ignore (not look for) the dialtone before dialing. (See Appendix A

for information on how to use AT commands.)

Communications Software Does Not Work

Some communications software packages need to be configured to the same COM

port and or IRQ as the modem. See the “Installing the Modem” for information on

how you determine your COM Port and IRQ number.

Does the communications software support this modem? See the Installing and Con-

figuring Communications Software section.

If you are using a different software from the one supplied with the modem (some

models of this modem may be shipped without communications software), try in-

stalling the supplied software and verify its functionality with the modem.

Nothing Appears OnThe Screen When IType

Issue the AT command ATE1to the modem to enable command echo. This will let

you see what you type.

Can’t Connect at 56K

Note: Current FCC regulations limit your maximum connection rate to 53Kbits / s.

The number you are calling may not support V.90 or K56flex protocols. Some ISPs

(Internet Service Provider) have special numbers that you must call to connect to

56K. Contact your service provider and ask if the number you are calling supports

V.90 or K56flex connections to their service.

Check the maximum speed setting in the Modem Properties window. On the task-

bar, click Start. On the Start menu, click Settings, then click Control Panels. Double-

click the Modems icon. Highlight your modem by clicking once on the icon next to

the modem and then click the Properties button. Select the General tab and look at

the setting in the Maximum speed box. Make sure this is set to 115200.

You may have other telephone devices connected to the phone line. To help your

modem achieve the best connection possible, remove all extra devices and their cables

from the telephone line when the modem is in use. This reduces the load on your

phone line and keeps signal attenuation to a minimum.

Keep the length of your phone line cable to 10 feet or less. Don’t use an unusually

long cable to connect to the phone line socket. If necessary, move the computer

closer to the phone socket. Don’t lay your cabling close to an electrical appliance like

a refrigerator or air conditioner unit. High current devices can transmit a 60 cycle

“hum” to your modem through the phone cord. This may cause frequent renegotia-

tions or line disconnects while the appliance is running.

The telephone line conditions at the time of your call may not let you connect at

56K. The modem has a connection sequence of K56flex, then V.90, then V.34, and

so on. The modem attempts to make the highest connect rate that your telephone

line can support at the time of negotiation. If the line conditions (noise, telephone

company routing, etc.) won’t allow a high data rate connection, then the modem will

automatically connect at the most reliable rate. Try making the call again after a few

minutes. The routing of the call may improve your chances of making a 56K connec-

tion.

If you are attempting to make a call from an office, are you using a direct outside line

or are you using a PBX hookup? If you have to dial “9” to reach an outside number,

you are using a PBX. The modem cannot connect faster then V.34 if you are using a

PBX. Try using the line that is connected to a fax machine. Fax machines are usually

connected to a dedicated line and not through the PBX.

Your phone line may not support a 56K connection. Or may support a 56K connec-

tion only intermittently. There are many conditions that must be met before a 56K

connection can be established. The telephone company must have you connected to

the PSTN (Public Switched Telephone Network) in a particular way. The modem

you are calling must support the same protocol. The phone line must be free of

distortion and noise. The phone wiring in your house or building must be in good

condition and so on. Check to see if you have good voice communications while

talking to friends or relatives. Do their voices sound distorted? Do you hear a “hiss-

ing” or “humming” sound in the background? Is there “popping” or “crackling” dur-

ing your call? These are phone line problems. In the case of distortion, your phone

line is bad. Humming may be due to the cabling inside your residence coming too

close to a high current appliance or you may have a cordless phone recharger base

connected to the phone line. Popping or crackling usually indicates a loose connec-

tion to the outside line or water dripping on the hookup outside your house.

The drivers for your modem are constantly being refined to address problems with

compatibility, interoperability, and performance. Check the Actiontec website on a

regular basis for driver upgrades. A problem connecting to a particular provider might

be fixed by a simple software upgrade.

Uninstalling the Modem

If you are uninstalling the modem in Windows 95 or 98 in order to upgrade your

drivers or obtain a clean reinstallation, it is important to follow these directions care-

fully.

When removing the drivers from a system running Windows NT, use the installation

utility. The utility has an option to remove your modem drivers.

Uninstalling in Windows 95 and 98

Step 1 On the desktop, right-click the My Computer icon and choose Properties

from the menu that appears. Select the Device Manager tab. Double-click

the Modems icon to expand the Modems section of the list. Highlight your

modem by clicking once on its icon, then click Remove.

Step 2 On the taskbar, click Start. On the Start menu, click Settings, then click

Control Panel and double-click the Modems icon. If your modem is listed,

highlight the modem by clicking once on the icon next to the modem and

then click the Remove button. Or, if the New Hardware dialog box comes

up, click Cancel.

Your modem should not be listed in the Modems section after you have

deleted it from the Device Manager. This could be a sign that your Plug-N-

Play settings are not correct. See “Does Not Install” for more information

about Plug-N-Play.

Step 3 Close all open windows and return to the desktop. On the taskbar, click

Start. On the Start menu, click Find, then click Files or Folders. Search for

the files listed below. Type in the name and extension (e.g. ltwave.inf) and

click the Find button. Once you find each of the files listed, highlight the

file by clicking once on the file name and then, in the Find All Files dialog

box, click to show the File menu and choose Delete. Delete all occurrences

of these files in your system.

ltcom.vxd

ltmodem.vxd

ltvcd.vxd

ltwave.inf

ltdfv.inf

ltdt.inf

ltmodem.sys

ltdsvd.dll

ltports.inf

If you cannot find a particular file, it usually means it was not installed. After all

instances of these files have been deleted, restart your system.

Note to users of Windows 95 and 98

If you are using Windows 95B (see “Do This First” for instructions on how to deter-

mine your Windows 95 version), you need only delete the files listed. In the case of

Windows 95 or Windows 95A, there are two additional files which Windows 95 or

Windows 95A generates when installing a third-party hardware peripheral. The file

is called oem#.inf. The number (#) used is generated by Windows 95 each time

an additional piece of hardware is installed. In the case of the modem, these files

could have any number between 1 and 99--oem8.inf, for example.

Close all open windows and return to the desktop. On the taskbar, click Start. On

the Start menu, click Find, then click Files or Folders. Type in *.infin the Named

box. Make sure your entire drive is selected and not just one subdirectory. Place a

check mark in the Include subfolders box. Be sure all the information is typed in as

shown below. Before beginning the search, click the Advanced tab.

Download from Www.Somanuals.com. All Manuals Search And Download.

At the Advanced settings window, type the following in the Containing text field:

V.90 PCI Windows Modem.Click Find Now.

When a file is found, it will have the name oem#.inf.To delete a file, highlight

the file name by clicking once and then choose Delete from the File menu.

Next, go to the Advanced tab and type the following in the Containing text field:

V.90_PCI_Windows_Modemas shown below.

After Windows finds the other file, delete it as before. Restart your system and follow

the installation procedures outlined in the “Installing the Modem.”

AT Command Set

AT Commands

AT commands are issued to the modem to control the modem’s operation and soft-

ware configuration. AT commands are commonly entered from a terminal program

such as HyperTerminal, and can only be entered while the modem is in command

mode. To enter an AT command, type:

ATXn

where X is the AT command, and n is the specific value for that command. Press

ENTER.

Commands are acknowledged with either text or numeric value response known as a

result code. In the case of multiple AT commands on the same command line, the

commands are executed in the order they are received. Should execution of a com-

mand result in an error, or a character not be recognized as a valid command, execu-

tion is terminated, the remainder of the command line is ignored, and the ERROR

result code is issued. If all commands execute correctly, only the result code associ-

ated with the last command shall be issued, even though all have been executed.

In the following listing all commands and command values accepted by the modem

are shown. Any entries other than those shown cause the ERROR result code.

+++

Escape sequence

The escape sequence allows the modem to exit data mode and enter on-line com-

mand mode. While in on-line command mode, you may communicate directly to

your modem using AT commands. Once you are finished, you may return to data

mode using the ATO command. A pause, the length of which is set by the Escape

Guard Time S-Register (S12--See the “S-Registers Reference” section of this manual

for details), must be used after an escape sequence is issued. This pause prevents the

modem from interpreting the escape sequence as data. The value of the escape se-

quence character may be changed using Register S2.

Repeat Last Command

This command repeats the last command string entered. Do not precede this com-

mand with an AT prefix or conclude it by pressing Enter.

Answer Command

This command instructs the modem to go off-hook and answer an incoming call.

Dial

This command instructs the modem to begin the dialing sequence. The dial string

(n, including modifiers and the telephone number) is entered after the ATD com-

mand.

A dial string can be up to 40 characters long. Any digit or symbol (0-9, *, #, A, B, C,

D) may be dialed as touch-tone digits. Characters such as spaces, hyphens, and pa-

rentheses do not count, they are ignored by the modem and may be included in the

dial string to enhance readability.

The following characters may be used as dial string modifiers:

Redials last number. Should be the first character following

ATD, ignored otherwise. The modem displays the dialing string

in the following format: “Dialingꢀxxxxxxx” where “xxxxxxx” is the

last number dialed.

Pulse dialing. (e.g. ATDPxxx. Dialing set to pulse as default.)

Touch-tone dialing (default). (e.g. ATDTxxx. Dialing set to tone

as default.)

Pause during dialing. Pause for time specified in Register S8

before processing the next character in the dial string.

Wait for dial tone. Modem waits for a second dial tone before

processing the dial string.

Wait for quiet answer. Wait for five seconds of silence after

dialing the number. If silence is not detected, the modem sends

a NO ANSWER result code back to the user.

Hook flash. Causes the modem to go on-hook for 0.5 seconds

and then return to off-hook.

Return to command mode. Causes the modem to return to

command mode after dialing the number, without disconnecting

the call.

memory for later dialing. The format for the command is &Zn = ”stored number”

where n is the location 0?3 to which the number should be written. The dial string

may contain up to 40 characters. The ATDS = n command dials using the string

stored in location n.

S-Registers Reference

S-registers generally affect how the AT commands perform. Contents of the registers

can be displayed or modified when the modem is in command mode.

To display the value of an S-register:

TYPE:

ATSn?

where n is the register number. Press ENTER.

To modify the value of an S-register:

TYPE:

ATSn = r

where n is the register number, and r is the new register value. Press ENTER.

Auto Answer Ring Number

Range:

Default:

Units:

0−255

rings

This register determines the number of rings the modem will count before automati-

cally answering a call. Enter 0 (zero) if you do not want the modem to automatically

answer at all. When disabled, the modem can only answer with an ATA command.

Ring Counter

Range:

Default:

Units:

0−255

rings

This register, Ring Counter, is read only. The value of S1 is incremented with each

ring. If no rings occur over a six second interval, this register is cleared.

AT Escape Character (user defined)

Range:

Default:

Units:

0−255

ASCII

This register determines the ASCII valued used for an escape sequence. The default is

the + character. The escape sequence allows the modem to exit data mode and enter

command mode when on-line. Values greater than 127 disable the escape sequence.

Command Line Termination Character (user defined)

Range:

Default:

Units:

0−127, ASCII decimal

13 (carriage return)

ASCII

This register determines the ASCII values as the carriage return character. This char-

acter is used to end command lines and result codes.

Response Formatting Character (user defined)

Range:

Default:

Units:

0−127, ASCII decimal

10 (line feed)

ASCII

This register determines the ASCII value used as the line feed character. The modem

uses a line feed character in command mode when it responds to the computer.

Command Line Editing Character (user defined)

Range:

Default:

Units:

0−32, 127

8 (backspace)

ASCII

This register sets the character recognized as a backspace and pertains to asynchro-

nous only. The modem will not recognize the backspace character if it is set to a value

that is greater than 32 ASCII. This character can be used to edit a command line.

When the echo command is enabled, the modem echoes back to the local DTE the

backspace character, an ASCII space character, and a second backspace character.

This means a total of three characters are transmitted each time the modem processes

the backspace character.

Wait Before Dialing

Range:

Default:

Units:

2-65

seconds

This register sets the length of time, in seconds, that the modem must wait (pause)

after going off-hook before dialing the first digit of the telephone number. The mo-

dem always pauses for a minimum of two seconds, even if the value of S6 is less than

two seconds. The wait for dial tone call progress feature (W dial modifier in the dial

string) will override the value in register S6. This operation, however, may be affected

by some ATX options according to country restrictions.

Connection Completion Time-Out

Range:

Default:

Units:

1-255

seconds

This register sets the time, in seconds, that the modem must wait before hanging up

because carrier is not detected. The timer is started when the modem finishes dialing

(originate), or goes off-hook (answer). In originate mode, the timer is reset upon

detection of an answer tone if allowed by country restriction. The timer also specifies

the wait for silence time for the @ dial modifier in seconds. S7 is not associated with

the W dial modifier.

Comma Dial Modifier Time

Range:

Default:

Units:

0-65

seconds

This register sets the time, in seconds, that the modem must pause when it encoun-

ters a comma (“,”) in the dial command string.

S10

Automatic Disconnect Delay

Range:

Default:

Units:

1-254

0.1 seconds

This register sets the length of time, in tenths of a second, that the modem waits

before hanging up after a loss of carrier. This allows for a temporary carrier loss

without causing the local modem to disconnect. The actual interval the modem waits

before disconnecting is the value in register S10.

S11

DTMF Dialing Speed

Range:

Default:

Units:

50-150

0.001 seconds

This register determines the dialing speed which is prefixed for each country.

S12

Notices

FCC Regulations

The following statements are provided in accordance with the Federal Communica-

tions Commission (FCC) regulations. Please read these statements carefully before

installing your modem.

FCC Part 68 Requirements

This equipment complies with Part 68 of the FCC Rules. On the bottom of this

equipment is a label that contains, among other information, the FCC Registration

Number and Ringer Equivalence Number (REN) for this equipment. If requested,

this information must be given to the telephone company.

The REN is used to determine the maximum number of devices connected to your

telephone line that will ring in response to an incoming call. In most, but not all,

areas, the total REN of devices connected to a line should not exceed five (5.0). To

find out the total permitted in your area, contact your local telephone company.

If your telephone equipment causes harm to the telephone network, the telephone

company can discontinue your service temporarily. If possible, the company 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 your right to file a complaint with the FCC.

Your telephone company can make changes in its facilities, equipment, operations,

or procedures that could affect the operation of your equipment. If so, you will be

notified in advance so you can make the changes needed to maintain uninterrupted

service.

If you experience trouble with this equipment, please contact the manufacturer at the

address given in this manual. The telephone company may ask that you disconnect

this equipment from the network until the problem has been corrected or until you

are sure that the equipment in is not malfunctioning.

This equipment may not be used on public coin service provided by the telephone

company. Connection to party lines is subject to state tariffs.

ference 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 and television reception, the user is encouraged to try to correct

the interference by one or more of the following measures:

•

Reorient the receiving antenna.

Increase the separation between the equipment and receiver.

CAUTION: CHANGES OR MODIFICATIONS NOT EX-

PRESSLY APPROVED BY THE PARTY RESPONSIBLE FOR

COMPLIANCE COULD VOID THE USER’S AUTHORITY TO

OPERATE THE EQUIPMENT.

Canadian Department Of Communications (CDOC)

Requirements for End Users:

Notice: The Canadian Department of Communications label identifies certified equip-

ment. This certification means the equipment meets certain telecommunications

network requirements. The Department does not guarantee the equipment will op-

erate to the user’s satisfaction.

Before installing this equipment users should ensure that connection to the line is

allowed by the local telecommunications company. The equipment must also be in-

stalled using an acceptable method of connection. In some cases, the company’s in-

side wiring associated with a single line individual service may be extended by means

of a telephone extension cord. Compliance with the above conditions may not pre-

vent degradation of service in certain 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.

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.
