2 Introduction

Motorola's SM56 Modem is a feature-rich modem at an attractive price. It provides high-speed communications between your personal computer and a remote location, such as an Internet

Service Provider (ISP), so you can:

Receive data at up to 56 Kbps in V.90 or K56flex modes

Get automatic fallback to V.34 (33.6 Kbps) rates in bad line conditions and on non-

V.90/K56flex headends

Use your computer as a telephone answering machine (TAM)

Send and receive faxes on your personal computer at rates up to 14.4 Kbps

Use your computer as a video phone to place and receive video phone calls

(Data/Fax/TAM/Speakerphone modem with video equipment)

Use your computer to conduct hands-off speakerphone voice calls

(Data/Fax/TAM/Speakerphone modem)

Important

The SM56 ISA modem runs on Windows 95, Windows 98, and it can be used by applications that run in an MS-DOS box (under Windows 95/98). Windows 95 and Windows 98 use the same

SM56 software builds.

The SM56 PCI modem also runs on Windows 95 and Windows 98. It does not directly support

Windows 95/98 DOS box applications. Refer to the Troubleshooting section for information on a third party COM port virtualizing/trapping application that allows the SM56 PCI modem to be used with DOS box applications.

Personal-computer OEMs that incorporate the SM56 can benefit from sizable cost reductions, hardware reduction, and lower power consumption. End users benefit from quick, easy and affordable software upgrades, which help them keep current with the latest communications technology.

Please check with your direct modem supplier for the latest software updates and other product information.

3 Personal Computer Requirements

Motorola performs rigorous, exhaustive testing on its modems. It developed a list of recommended personal computer features that perform well with the SM56. The information includes qualified

CPUs, Level 2 cache requirements, operating systems, RAM requirements, and third-party sound card compatibility. However, in today's dynamic technology markets, it is not possible to test all components and combinations on all systems.

This section outlines minimum system requirements for SM56 operation. On these systems, CPU loading was found to be acceptable and the modem demonstrated good performance over the entire network model.

Important: SM56 operation is not limited to the personal computer systems listed here.

Recommended CPUs

The SM56 modem has been qualified (tested for processor loading and TSB network model coverage) on the following processors:

Intel Pentium, 150MHz with MMX, 256K Level 2 (L2) cache

Intel Pentium, 200MHz, 256K L2 cache

Intel Pentium II

Intel Pentium Pro

Intel Celeron (Pentium II, 266MHz, no L2 cache)

The SM56 functions satisfactorily on the following systems. However, it has not been fully qualified (it was not tested for processor loading or TSB performance):

AMD K6, 233 MHz, 256K L2 cache

AMD K6-2, 256K L2 cache

Cyrix 6x86MX, 266MHz, 256K L2 cache

The SM56 does not function on the following CPUs, whose floating-point performance is insufficient:

Cyrix MediaGX

Cyrix MediaGXM

Cyrix 6x86

Level 2 Cache Benefits

Level 2 (L2) cache is an instruction memory (SRAM) bank that resides outside the CPU core. It holds many instructions close to the CPU, to reduce the need for the processor to use slow access cycles fetching instructions from main memory (DRAM). Eliminating most CPU accesses to main memory considerably improves overall system performance.

The SM56 Software Modem works best when a minimum of 256K L2 Cache is installed on the computer system motherboard to minimize processor loading. Intel's Celeron (266MHz PII) systems do not have L2 cache. Although the SM56 operates on those systems, host processor loading increases in the absence of L2 cache.

Compatible Operating Systems

The SM56 modem will run on the following operating systems:

Windows 95 (OEM Service Release 2.0 or later)

Windows 98

DOS Box under Windows 95/98. Note that the SM56 PCI modem does not include direct DOS box support. Refer to the Troubleshooting section for information on working around this limitation.

System RAM Requirements

The SM56 Modem operates on systems that have the minimum RAM required by the installed operating system. As with L2 cache, the more main memory, the better. The recommended RAM is twice the required minimum. This reduces slow hard-disk swapping and improves overall system

performance... especially when executing numerous concurrent processes. The minimum RAM requirements are:

Windows 95/98 16 MB

4 Preparing the Computer for SM56 Installation

To ensure problem-free installation of the SM56 modem, ensure that an IRQ is available, as follows.

1. In Win95/98, open the Control Panel.

2. Double click the System icon.

3. Select the Device Manager tab.

4. Highlight the Computer icon.

5. Select the Properties radio button.

6. Ensure that the Interrupt Request (IRQ) radio button is selected.

This displays the IRQ lines that are in use on the computer. Available lines are not shown in the list. To install the SM56 ISA modem hardware, interrupt line 3, 4, 5, 6, 7, or 9 must be available.

The PCI SM56 software modem can use an IRQ in the range 3 through 15.

If there is no IRQ line available for the SM56 disable one of the COM ports in the BIOS.

Note: If you are using a Windows 95/98 DOS box application, the modem requires two IRQs.

Refer to the Troubleshooting section in this document, or to the on-line User's Guide for more information on DOS application support. You can access the User's Guide through the modem

Control Panel.

Important: The SM56 PCI modem does not directly support DOS box applications. Please refer to the Troubleshooting section for information on how to get around this limitation.

To ensure that COM Port 2, 3, or 4 is available, you can use the following steps:

1. Open the Control Panel.

2. Double click the System icon.

3. Choose the Device Manager tab.

4. Highlight the Ports (COM and LPT) branch.

5. Expand the branch to see which ports are installed on the computer.

To install the SM56 ISA modem so that it is accessible through older application software and

DOS programs, COM port 2, 3, or 4 should be available. If none of these ports are available, you must disable one of the COM ports in the BIOS.

5 Installing Modem Hardware

Hardware Installation:

Install the modem card as follows.

1. Power down the personal computer.

2. Locate a vacant bus connector (ISA or PCI, depending on your hardware) and insert the modem card.

3. If using the SM56 Data/Fax/TAM/Speakerphone modem, connect the sound subsystem interface cable(s) to the modem card (via the internal TAPI connector or using the audio jacks

-- refer to the information above on sound card compatibility.)

4. Connect the modem Line input to an analog phone jack using an RJ-11 phone cable. Optionally, connect a telephone handset to the Phone input on the line interface card. The external telephone cable connections are as follows.

5. Replace the personal computer cover and power the personal computer on.

6 Installing SM56 Software

6-1 Installing SM56 Software on Windows 95/98

IPCI Slots

The SM56 for PCI is PCI Plug and Play compliant. It requires one IRQ ( IRQ 3, 4,...15) and one memory mapped base address.

Windows 95/98 assigns the modem a COM port number. The SM56 installation software attempts to negotiate a COM port number in the range of 1-4 in order to support older software and DOS games. Note that the SM56 PCI modem does not include direct DOS box support. Please refer to the Troubleshooting section for information on how to get around this limitation.

Installing on Windows 95/98

(Note: The Install Wizard may vary slightly with different versions of Windows 95 and Windows

98.)

On starting Windows 95/98 for the first time after installing the SM56 (ISA or PCI) line interface card, the Windows 95/98 Configuration Manager detects the new hardware, assigns resources to it, and then displays a window requesting the modem software drivers. This indicates that the

Configuration Manager is looking for the information (INF) file, which contains information about the modem, including device type (Modem), device driver information (the name of the driver that will control the modem) and the AT command/response sets that it supports.

In response to the request window, insert the distribution CD-ROM that contains the SM56 installation software. Select Driver from Disk Provided by Hardware Manufacturer. Windows should find the information on the disk and identify the device as the SM56 Modem Line Interface

Card. It copies the files from the install disk to the computer.

Note: The SM56 install program may display a message box that reports Cannot locate file

_inst32.ex_... If this occurs, browse and re-point the path to the SM56 installation CD ROM again. Then click OK.

On boards that have voice capabilities (SM56 Data/Fax/Voice models), another device is found after the modem has been installed. Windows notifies you that it has found a Serial Wave Device for the modem and prompts for a Wave Device driver. Re-point Install Shield to the SM56 distribution disk, and click OK.

When these two devices are installed, the SM56 Modem Setup program runs.

SM56 Modem Setup for PCI

The modem setup program for PCI does not prompt for user input during installation. It defaults to

USA country code and Domestic English as the language for the Help files. If you wish to change either of these settings you may do so via the SM56 PCI Control Panel application (see

Verifying

Correct SM56 Installation

section) after setup is complete. Also, for SM56

Data/Fax/TAM/Speakerphone modems the microphone and speaker gain selections are done via

the Control Panel application (under the Advanced tab). The SM56 PCI Data/Fax/TAM only modem does not have a Microphone/Speaker Gain selections.

Determining Microphone Gain Setting

If you connect the modem to the sound card through the internal TAPI connector, use the following procedure to determine the appropriate microphone gain.

Determine whether the sound card has applied any gain to the microphone signal that is presented at its TAPI connector.

Note: The SM56 PCI modem (Data/Fax/TAM/Speakerphone only) Control Panel application provides slider bars so users can fine tune speaker and microphone gains more easily.

6-2 Installing SM56 Software on Windows NT 4.0

Important -- The SM56 software for Windows NT is Data/Fax only, there is no speakerphone or TAM supported.

Windows NT 4.0 does not fully support plug and play (PnP). Therefore, after installing the modem board in the computer and booting, the operating system will not automatically recognize that new hardware is present. You must manually install the modem as follows:

Step 1 -- Install a COM port for the modem

You must install a COM port for the SM56 modem as follows:

1. Open the Windows NT Control Panel.

2. Double click the Ports icon. The Ports window opens.

Then click Open, then click OK.

6. Select the Motorola SM56 Modem (note that the product name listed will vary depending on which modem you have -- Data/Fax/, Data/Fax/TAM, etc.) from the list. Click Next.

7. Click the port number selected in Step 1 above to highlight it as the COM port for the modem.

Then click Next. The wizard will now copy all the necessary files and install the SM56 modem on your PC.

8. When complete, restart the PC to activate and start the COM port and SM56 modem devices.

You are now ready to use the modem.

7 Verifying Correct SM56 Installation

Verify that the SM56 software and hardware installation was completed correctly as follows.

Verifying SM56 Software Installation

1. Verify correct COM port selection.

You can check COM port installation through the Modems icon in the Control Panel or through the SM56 Control Panel application (see below). Normally, the SM56 will install on COM2,

COM3, or COM4. Sometimes, however, depending on your computer system setup or Windows setup, the SM56 may install on COM5 (or higher).

Although the modem functions correctly on COM5, many Internet Service Provider (ISP) software applications (such as AOL) do not work if the modem is on a COM port number higher than

COM4. If the SM56 installs on COM5 (or higher), refer to the Troubleshooting section for assistance.

2. Run simple diagnostic from the SM56 Control Panel.

The SM56 software modem provides an informative Control Panel that reports:

Modem status: in use/not in use; dialing; negotiating a connection; actual connect rate (updated in real time during a connection)

A button to access the on-line User's Guide

The SM56 Control Panel program also provides access to two Windows components:

COM port and IRQ information

A diagnostic utility that sends the modem ATI commands and displays the results: software build, modem type (DF or DFV), and more.

To access the diagnostics option from the Control Panel, click Properties; select the Diagnostics tab; select the SM56 Modem from the list; and then click More Info. If the driver is properly installed, a dialog box appears, with responses to the ATI commands as shown in the example below. Refer to the AT Commands section in the on-line User's Guide for an explanation of ATI commands.

Verifying SM56 Hardware Operation

To verify correct SM56 modem card hardware operation (up to the isolation transformer), you can use the following loop back test procedure.

1. Important: Remove the telephone line connector from the modem card.

2. Select Start.

3. Select Programs-->Accessories-->HyperTerminal.

4. Double click the Hypertrm.exe icon.

5. Optionally, select a connection name and icon.

12. Enter AT&T1 <cr> . Wait a few seconds.

13. Type some letters at the keyboard. If the hardware is functioning correctly, the letters you type appear on the HyperTerminal display.

8 Changing the Operating System

Windows 98 Upgrade Error Message

If the SM56 modem is installed on a Windows 95 PC, and then the system is upgraded to Windows

98, the following error message appears when Windows 98 starts:

Duplicated device: vcd

To remove the error, edit the SYSTEM.INI file and locate the line that reads:

Device = *vcd

Delete this line. Save the modified SYSTEM.INI file and restart Windows 98. You will no longer get the error message.

9 Using the SM56 Modem

32-Bit Windows 95/98 Applications

Because 32-bit Windows 95/98 applications use TAPI for communicating with modems, using the

SM56 is as easy as selecting the SM56 modem by name from the list of available modems.

16-Bit Windows 95/98 Applications

Because 16-bit applications cannot use the TAPI interface, there is a bit more setup needed.

1. Select Motorola SM56 modem from the list of supported modems (if the SM56 modem is

not shown, select Hayes Compatible modem).

2. Configure the application's COM port selection. Use the COM port assigned to the SM56

modem.

3. If the application requires it, enter specific AT commands for the SM56 modem. (For a

full list of AT commands, refer to the SM56 on-line User's Guide). Some typical AT

commands are listed below.

DOS-Based Applications and Games

Important: The SM56 PCI modem does not include direct DOS box support. Please refer to the

Troubleshooting sections for information on a way to get around this limitation.

The SM56 ISA modem can be used in DOS only through a Windows 95/98 DOS box.

DOS support is achieved by virtualizing the standard I/O and IRQ assigned to a COM port. This means that the SM56 drivers capture and redirect all I/O to/from the standard I/O address for the

COM port to which it assigned. In simpler terms, you tell the application the COM port of the

SM56, and then use all the standard I/O and IRQ settings. Standard I/O addresses and IRQs for

COM Ports 1-4 are as follows:

COM Port IO Address IRQ

1 3F8 4

2

3

4

2F8

3E8

2E8

3

4

3

To determine the SM56 COM port number, open the SM56 Control Panel and select the

Diagnostics tab. The COM port number to which the SM56 modem is assigned is listed here.

Configure your application to use this COM port. For example, if the SM56 modem has been assigned COM 3, configure your application to communicate through COM 3.

Enter the AT commands for the SM56 modem as required by the application. Some typical AT commands are as follows.

AT Commands Commonly Needed by Applications

Applications generally prompt for the following commands.

Initialization* AT&F

Hangup

Dialing string

Answer string

ATH0

ATDT

ATA

*Some games require that the modem refrain from performing error correction and data compression. In these cases, use the initialization string AT&F\N0.

For a full list of AT commands, refer to the on-line User's Guide.

11 Troubleshooting

If there is a problem making or receiving a call or transmitting data, and your communications application does not explain the problem, check the following list of symptoms and tips.

The modem installs at COM 5 (or higher)

Some ISP applications, such as America on-line, do not communicate with a COM port higher than COM4. If the SM56 installs on COM5 or higher, force the modem to a lower COM port as follows.

1. Open the SM56 Control Panel application.

2. Select the Advanced tab.

3. Click on the radio button for the desired COM port. Note that unavailable COM ports are grayed out and not selectable.

Note: For SM56 ISA modems Build 58 and later include this feature on the Control Panel applet.

If using earlier builds, edit the PortName data in the Windows Registry HKLM-->Enum--

>ISAPNP-->nnnn, where nnnn corresponds to the modem's plug and play ID. Change PortName data to the desired COM port. The changes take effect as soon as the Registry editor (REGEDIT) is closed. There is no need to restart the PC.

Windows 95/98 DOS box applications do not work with the modem

1. The SM56 PCI modem does not directly support Windows 95/98 DOS box applications. If you are using the SM56 PCI modem you must use a third party application that traps and virtualizes the COM ports. One such application is provided by Pacific Commware, Inc.

(Ashland, Oregon). They can be found on the Web at www.pacificcommware.com. The application is called TurboCom/95 Pro, and works on Windows 95 and Windows 98 platforms. Note that Motorola have not completely tested and qualified this product for SM56

DOS box support, but have verified basic functionality.

2. If using the SM56 ISA modem, open the Control Panel.

3. Double click the System icon.

4. Expand the Modem branch.

5. Double click the Motorola SM56 modem.

6. Select the Modem tab. Make a note of the COM port number.

7. Select the Resources tab. Make a note of the IRQ number listed.

8. For DOS support to operate correctly, the SM56 modem cannot occupy the standard IRQ for the COM port number.

9. Uncheck the Use Automatic Resources check box.

Double click on the Interrupt Request label and change the IRQ to a different level that is not in conflict with another device. (If there is no free IRQ: free one, or change other device IRQ levels to free a non-standard IRQ).

There is no dial tone

1. Ensure that the telephone cable is securely connected at both ends.

2. Unplug the telephone line cable from the computer, and connect it directly to a telephone from the wall outlet. Check for a dial tone. If there is none, the problem is in the telephone line or system. Call the service provider.

The modem cannot complete a connection to another modem

1. Ensure that your modem is dialing the correct number. Ensure that you've specified the correct area code, if one is required.

2. Determine whether the remote modem is correctly configured to communicate with yours.

The modem does not answer incoming calls

1. Ensure that the automatic answer parameter is set to one of the enabled options, using the

ATS0 command (ATS0=1 to answer after one ring, and so on).

2. Ensure that no other devices, such as fax or answering machines, are answering calls before the modem does.

The modem disconnects while transmission is in progress

1. Ensure that the telephone cable is securely connected at both ends.

2. Ensure that call-waiting is disabled. In most areas, the command *70 or #70 disables callwaiting. Check with your telephone company for the correct key sequence. (With call-waiting, the incoming call's click sound may be disrupting your call.)

Data is not transmitted or received for unusually long periods of time

Re-dial the call. (The telephone line connection may be poor.)

The computer runs slower than usual

1. Close any open applications that you are not using.

2. For the SM56 for ISA only: try adjusting the modem's CPU Usage option from High to

Medium; or Medium to Low. This is in the SM56 Control Panel application. This option is not available for the PCI modem.

You cannot enter tone selections successfully when calling tone-driven applications

When dialing a remote system that requires you to enter selections using the telephone keys, such as a voice-mail depot or bank-account information provider, you can lengthen the duration of the tones your modem sends, so that the remote system can detect them better. To adjust DTMF tone length, use the AT+VTDn command, where n specifies the tone duration.

The modem does not respond to AT commands

1. Ensure that your communications software is configured to use the same COM port as the modem's COM port.

2. Reset modem parameters to default options by entering AT&F; then re-enter custom options.

3. SM56 builds after Build 50 require setting the S46 register to 23 before AT&T1 will perform the Local Analog Loop(LAL) back hardware test.

The modem responds to commands, but they do not appear on the screen

Ensure that the Echo option is enabled by entering ATE1.

13 Understanding SM56 Windows Logo Certification

After rigorous testing at a Microsoft Windows Hardware Quality Lab (WHQL), the ISA busbased SM56 software modem met the stringent qualifications to receive the Designed for

Microsoft Windows logo. The PCI modem will be qualified later. The logo is targeted at commercially marketed desktop applications that run on the latest released versions of Windows

95, Windows 98, and Windows NT Workstation. It is not intended for client/server or Windows

NT Server applications. The goals of the logo certification program are to improve Windows hardware and software quality, increase end-user satisfaction, and reduce support costs.

To receive the logo, a product must show proof of compatibility with Windows 95/98 and NT. The

SM56 Software Modem passed the stringent tests to show that, among other capabilities, it:

Installs and registers itself properly with the operating system

Is reliably functional and stable

Removes itself (minus its core components) using an automated uninstaller

Supports Universal Naming Conventions (UNC) and Long File Names (LFN)

The modem also passed a host of other performance and feature-set tests of its data, fax, and voice modes.

What does the logo mean for the SM56 ISA modem? It means that Motorola and its OEMs, system integrators, and VARs can now use the Windows logo on their products and packaging, and on advertising, collateral, and marketing materials. This signals end users that the SM56 software modem is tested and fully functional on Windows 95/98 and Windows NT 4.0; that it is designed to provide optimum usability and compatibility; and that it takes advantage of the latest technologies provided by these operating systems. It makes users feel more comfortable about purchasing the product, and it assures them of more complete satisfaction while using it.

The Windows logo also means that the SM56 software modem is included on Microsoft's Windows

Hardware Compatibility List (HCL) under "Logo," reinforcing to customers and end-users alike that it meets Microsoft's strict requirements and operates properly with Windows operating systems.

In summary, Windows Logo certification increases recognition and adoption of SM56 Software

Modem technology worldwide. It demonstrates Motorola's long-term commitment to providing high performance, quality products.

14 An Overview of the V.90 Standard Protocol

In February 1998, the International Telecommunications Union (ITU) formulated the V.90

industry-standard protocol for 56K modems. Before the adoption of the V.90 standard, 56K modems complied with one of two pre-standard implementations: K56flex or X2 technology.

Unfortunately for ISPs and end-users, these technologies were not compatible. ISPs had to worry about which standard to employ. End users had to be sure to purchase modems compatible with their ISP's equipment.

Upgrading Motorola's SM56 K56flex modems to V.90 is a software-only upgrade. There is no change to the line interface hardware. This makes it easy for pre-V.90 users to upgrade their system to V.90 compliance.

Note: sometimes V.90 is referred to as V.PCM. PCM is an acronym for Pulse Code Modulation.

With V.90, high-speed downstream (from Internet to personal computer) data transmission is accomplished using PCM techniques. Before the ITU formulated its standard V.90 protocol, the industry typically referred to it as V.PCM. This name is fading from use.

V.90 technology allows users to connect to the Internet at rates up to twice as fast as those of V.34

(33.6Kbps) modems. The maximum receive (downstream) rate is 56Kbps, while the return path

(upstream) connects at V.34 rates up to 33.6 Kbps. This is perfect for Internet connections, where most data is transferred downstream.

The SM56 begins connections by attempting a V.90 connection to the headend. If the headend is not V.90, the SM56 automatically switches to K56flex mode. If K56flex mode fails (when, for example, the headend uses X2 technology, or there is a noisy phone line condition), the SM56 drops to V.34 rates. This auto-mode switching mechanism ensures maximum compatibility with all remote headends.

Note: First row of this table represents the code displayed when call progress is set to 0.

When call progress is 0, no rate is displayed in the connect message, only the word

"CONNECT", which is represented by the numeric code "1". For all other call progress settings, the rate information is displayed and reflected in the numeric code displayed.

Appendix D - Connect Message Examples

The following table shows a few examples of how the long-form connect message will look, based upon the settings of the /V (connect message) and X (call progress) strap settings.

Appendix E - Homologation Testing Command

Homologation Automated Test Options

This command is a special test hook that causes the modem to go off-hook and generate a continuous signal. In order to enable this command you must first type the command ATS46=0.

The signal that is specified by the AT*HO options is sent over the modem line interface as long as AT*HO is set to a non-0 option. This capability is necessary for measuring the inband and outband noise condition for each signal.

Spectrums

Spectrums are affected by the transmit level and other options.

DTMF

When DTMF is selected, the modem goes off-hook and generates the digit specified as option 2.

This is a continuous DTMF signal (no off time). It is necessary to characterize the inband and outband noise.

The AT*HO command takes between 1 and 4 option parameters.

This command has the format:

AT*HOa,b,c,d where: a = a parameter 1 option b = a parameter 2 option c = a parameter 3 option d = a parameter 4 option

Examples:

AT*HO1,15,0,1 represents V.21, -15dB, Answer Band, Space

AT*HO12,4 represents DTMF, digit 4

"This equipment has been approved to [Council Decision 98/482/EC - "CTR 21"] for pan-

European single terminal connection to the Public Switched telephone Network (PSTN).

However, due to differences between the individual PSTNs provided in different countries, the approval does not, of itself, give an unconditional assurance of successful operation on every

PSTN termination point.

In the event of problems, you sholud contact your equipment supplier in the first instance"
