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

•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.

•Use your computer as a telephone answering machine (TAM) -- not available on Data/Fax

modems.

•Use your computer to conduct hands-off speakerphone voice calls (Data/Fax/Speakerphone

modems only).

Important: There are three different SM56 modem types, and each supports a different feature-

set, as follows:

main window the product name of your installed modem is displayed.

Personal-computer OEMs that bundle 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.

3Personal Computer Requirements

Motorola performs rigorous, exhaustive testing on its modems. It has 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 minimum

•Intel Pentium, 200MHz, 256K L2 cache minimum

•Intel Pentium II

•Intel Pentium Pro

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

•AMD K6-2 with 3DNow!, 256K 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

•Cyrix MII, 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 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

•Windows NT

•DOS Box under Windows 95/98.

System RAM Requirements

The SM56 operates on systems that have the minimum RAM required by the installed operating

system. As with L2 cache, the more main memory, the better. This reduces slow hard-disk

swapping and improves overall system performance....especially when executing numerous

concurrent processes.

4Preparing the Computer for SM56 Installation

To ensure problem-free installation of the SM56, ensure that an Interrupt Request (IRQ) line 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/unused lines are not shown

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

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

it's IRQ.

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 SM56

modem Control Panel application.

Also, you must ensure that one of COM Port 2, 3, or 4 is available for the SM56, as follows:

1. Open the Windows Control Panel.

2. Double click the System icon.

3. Choose the Device Manager tab.

4. Expand the Ports (COM and LPT) branch to see which COM ports are already installed.

To install the SM56 so that it is accessible to older application software and DOS programs, the

modem needs to be installed on one of COM port 2, 3, or 4. If none of these ports are available,

you must disable one of them in the BIOS.

5Understanding Sound Card Compatibility and Installing the SM56

Hardware

Note: This section applies only to Data/Fax/Speakerphone modems.

Before discussing modem board installation, let's review the optional sound card connections for

the SM56. Recall that SM56 Data/Fax/TAM modems do not support the sound subsystem, even

though you can record and play back answering machine messages through your sound card

using them.

Sound Card Compatibility:

The SM56 requires a sound card to use its speakerphone capabilities. The Data/Fax/TAM modem

requires the sound card for local message playback which occurs through the host PC bus, not via

external wire connections. For this reason there are typically no TAPI connectors or

speaker/microphone jacks provided on Data/Fax/TAM and Data/Fax modems. Instead, these

modems usually have a local call progress speaker mounted on them, while speakerphone

supporting modems do not (since they can be connected to the sound board).

Typically, there are two methods for interfacing the Data/Fax/TAM/Speakerphone modem to a

sound card:

•Internal speaker/microphone TAPI connector/header

•Microphone and Speaker jacks mounted on the modem board

TAPI Connector

Using the on-board TAPI connector requires a sound card that also has a TAPI-style connector,

which has pins that provide analog microphone output and speaker input connections. Many

sound cards have one or more CD or auxiliary connectors, but these do not provide the required

microphone output for the SM56. To ensure compatibility, check the sound card specifications;

one connector must provide a microphone output as well as a speaker input.

You can make up or purchase a cable that routes SM56 microphone and speaker signals to the

sound card. Locate the 4-pin header connector on the SM56 card. The SM56 reference design

connector pin-out is as follows.

SM56 Pin Signal

1 Ground

2Microphone In

3 Ground

4Speaker Out

Important: Different modem manufacturers may vary this pinout. Consult their modem

documentation to verify. Also, different sound card connector pinouts may be different, in which

case the audio cable will need to have cross-over wires to match the pin signals. Make sure to

consult your sound card documentation for pin-signal details.

On-Board Microphone and Speaker Jacks

If the sound card does not provide a TAPI-style connector, you can connect the SM56 modem to

the sound card through optional on-board microphone and speaker jacks. Ask your modem

supplier for a board with this option. The microphone jack allows for the direct connection of a

microphone to the SM56 modem card. The sound card also has a microphone input.

•To use speakerphone applications with the modem, connect your microphone to the

microphone input jack on the SM56 modem card. You can then talk into your

microphone and hold a conversation with the remote party.

•To record audio (such as a voice mail greeting) on the personal computer, attach the

microphone to the microphone input jack on the sound card. Note that some

telephony applications may support audio recording through the modem jacks, e.g.

Bitware, in which case you do not need to switch the microphone to the sound card input

jack.

You may be able to create a special cable or use a T-splitter to connect one microphone to the

input on the modem and the sound board simultaneously.

The speaker out jack on the modem board can be used in one of two ways:

•To directly connect powered speakers to it.

•To connect it to the sound card line-in jack (this allows the speakers to remain plugged

into the sound card at all times).

SM56 Hardware Installation Procedure:

1. Power down the personal computer.

2. Locate a vacant PCI bus connector.

3. If using the SM56 Data/Fax/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.

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

6Installing SM56 Software on Windows 95/98

Note: Windows 95/98 assigns the modem a COM port number. To support older software

applications and DOS games the SM56 installation software attempts to negotiate a COM port

number in the range of 1-4. If the install picks a higher COM port, you can force the COM port

selection via the Control Panel application after install is complete.

Installing on Windows 95/98

(Note: The Install Wizard may vary slightly with different versions of the OS and different

service packs)

On starting Windows for the first time after installing the SM56 line interface card, the Windows

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. Select Driver from Disk Provided by Hardware

Manufacturer (or Have Disk depending on the OS version) and browse to where the SM56

drivers are located. Windows should find the information on the disk and identify the device as a

SM56 Modem. It then copies the files from the install disk to the computer.

Important: The install program may display a message box that reports Cannot locate file.... If

this occurs, browse and re-point to where the SM56 driver files are located. Then click OK.

Installation will now complete.

On Data/Fax/TAM and Data/Fax/Speakerphone modems, 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 to the SM56 driver location and click

OK.

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

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 online Help file. If you wish

to change these settings, and/or the COM port selection, you may do so via the SM56 Control

Panel application (Start->Settings->Control Panel, then double-click the SM56 Modem icon)

after setup is complete. Also, for SM56 Data/Fax/Speakerphone modems the microphone and

speaker gain selections may be done via the Control Panel application (under the Advanced tab).

Also, DOS box support is disabled after the SM56 is installed. After install is complete, you

must enable it via the Advanced tab in the SM56 Control Panel application. Make sure the DOS

box check box is checked. If not, click it to check it, exit the SM56 Control Panel application and

restart the computer. You must restart the computer to complete DOS box enabling.

7Installing 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.

3. Select Add.

4. Select a COM port number (in the range 1-4 preferably) that is not already installed, and

allocate to it the standard resources as follows:

COM Port IO Address IRQ

13F8 4

22F8 3

33E8 4

42E8 3

5. When your selections are complete click OK.

6. You will be prompted to restart the computer, do not do so yet. Select Don't Restart Now.

7. Close the Ports window.

Step 2 -- Install the SM56 modem software

1. Open the Windows NT Control Panel.

2. Double click the Modems icon....the Install New Modem dialog appears.

3. Click the "Don't detect my modem; I will select it from a list" check box. Then click Next.

4. Click the Have Disk button.

5. Browse to the Windows NT SM56 modem install software. Click misgmodm.inf to highlight

it. 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.

8Verifying Proper Modem Installation

Verify that the SM56 software and hardware installation has 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

any COM port, many software applications do not work if the modem is on a COM port number

higher than 4. If the SM56 installs on COM5 (or higher), you can force it to a lower COM port

via the SM56 Control Panel applet.

2. Run modem diagnostic from the SM56 Control Panel.

The SM56 software modem provides an informative Control Panel application 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.

•COM port selections.

•Country and language selections.

•Data/Fax/Speakerphone modems only -- microphone and speaker gain selections.

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

•COM port and IRQ information

•A diagnostic utility that issues various ATI commands to the modem and displays the

responses: software build, modem type, and more.

To open the SM56 Control Panel application, selection Start, Settings, Control Panel, and then

double click the SM56 Modem icon. To access the diagnostics option from the Control Panel

applet, click Properties; select the Diagnostics tab; select the COM port corresponding to the

SM56 Modem from the list; and then click More Info. If the driver is properly installed, within

a few seconds a dialog box appears, with responses to the ATI commands. Refer to the AT

Commands section in the on-line User's Guide for an explanation of these commands and

responses.

Verifying SM56 Hardware Operation

To verify correct SM56 modem card hardware operation (up to the isolation transformer), you

can use the following local analog loopback (LAL) 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.

6. In the Connect Using window, select Motorola SM56...... modem. Click OK.

7. Enter a number in the Phone Number box...any number since we will not be dialing it. Click

OK.

8.On the next screen select Cancel.

9. Enter AT and hit <Enter>.

The response OK should appear.

10. Enter ATS46 = 23 and hit <Enter>.

11. Enter AT&T1 and hit <Enter>. Wait a few seconds.

12. Type some letters at the keyboard. If the hardware is functioning correctly, the letters you

type appear on the HyperTerminal display.

13. To exit this test mode, type +++ in quick succession (note no carriage return) to escape to

command mode, then type ATH <Enter>.

9Changing the Operating System

The SM56 Modem software is the same for Windows 9 and Windows 98. If the modem is

installed on Windows 95 and you upgrade to Windows 98, the SM56 will continue to function as

before. No new drivers are required.
