Introduction

Modem

About the

This chapter summarizes the features and options of the 326X Series Modem. The series includes:

• The 326X V.32bis Series Modem, which operates in V.32bis modulation mode

• The 326XFAST Series Modem, which can operate in V.34 modulation mode

• The 326XFAST-SDC Series Modem, which can operate in V.34 modulation mode and the Synchronous Data Compression mode

In this guide, references to the modem apply to all of the above, unless stated otherwise.

IMPORTANT: When you select a modulation mode, you must ensure that the Max Rate (A T*MX) and Mi n Ra te (AT*MN) p arame te r options are within the v ali d r ange for the mode .

The modem provides reliable data communication over 2-wire dial lines and 2-wire or 4-wire leased lines, depending on the model. Dial lines are public lines to which all telephone users have access; leased lines, also called private lines, provide a dedicated connection, over lines provided by the telephone company.

Whether you use dial or leased lines, you can operate the modem as follows:

• Using the front panel: control keys and liquid-crystal display (LCD)

• Using industry-standard (AT and AT&), and Motorola-enhanced (AT commands from an attached terminal, or commands from an asynchronous communications software package running on an attached PC

•From a network management system (NMS)

• Using call establishm ent methods, such as V.25bis or LPDA2 automatic call units (ACUs)

Figure 1-1 shows desktop, or standalone, modems. The device is also available in high-density nest cards, which offer the same features, and can be installed in Motorola’s Modulus 9-slot and Modulus 21-slot rack-mounted enclosures.

Operating the Modem from the Front Panel

The front panel menus ar e or ganized f unctiona lly so t hat o peration is easy for novice and advanced users.

Refer to Chapter 3, Getting Started, to learn about front panel operation.

1-4 About the Modem

Selecting Programmed Option Sets

Option sets make it easy to use a modem with common applications, including:

• Asynchronous and synchronous answering

• Asynchronous and synchronous dialing

• Leased line with dial restoral operation

Four sets of options are stored in nonvolatile memory. If none is appropriate to an application, you can customize an option set, and save it in nonvolatile memory.

Refer to Chapter 4, Configuring the Modem, for more information on option sets.

Automatic Calling Interfaces (ACUs)

The modem supports three automatic calling interfaces (also known as Auto-Call Units). ACUs let you execute functions directly from a keyboard.

AT ACU

The asynchronous AT ACU is compatible with the industry-standard AT command set. AT Commands provide a standard modem communications interface, allowing you to configure and operate your modem from a terminal or PC keyboard.

About the

Modem

Using the AT-compatible command set (AT and AT&), you can, for example, dial and receive phone ca lls. Motorola ’s extended AT command set (AT important parameters used in configuring advanced modem features.

Refer to Chapter 3, Getting Started, and Chapter 5, Using the AT Automatic Calling Interface, to learn more about the AT ACU and AT command syntax.

) includes other

V.25bis ACU

For sync or async auto-calling, use the ITU-T V.25bis compliant ACU. With either the AT or V.25bis ACU, you can store, dial, or change up to nine phone

numbers in the modem's electronic telephone book, directly from your terminal. Refer to Chapter 3, Automatic Calling Interfaces, in the 326X Series Modem

Reference Guide, for details .

LPDA2 ACU

The LPDA2 feature lets you use IBM dial and leased line restoral applications with LPDA2 Dial and Disconnect commands. LPDA2 allows Netview and other IBM applications, like POS outbound dialing applications, to control dialing.

In dial applications, LPDA2 eliminates the need for additional ports and equipment that had been required to support external 801 auto-dialing equipment in IBM environments.

About the Modem 1-5

Modem

About the

Managing a Modem

In leased line operati on, while conn ected on the dial line, the modem can monitor for LPDA2 commands in the data stream. If the local modem detects an LPDA2 command, the frame that is being processed is aborted. This prevents the remote DTE from processing the command frame as valid data.

Refer to Chapter 3, Automatic Calling Interfaces, in the 326X Series Modem Reference Guide, for details .

Integral Network Management by Motorola’s 9110, 9000-UX, and 9000-PC

Network Management Systems (NMS) is standard. The NMS can configure, monitor, and control local and remote modem operation.

An NMS continuously polls modems to collect management information and check status. Network management traffic, including alarms, commands, events, and polling, is transp orted to re mote modems on a n in- band cha nnel t hat d oes not disr upt user data traffic nor consume user bandwidth. The modem supports a daisy-chain network management interface, reducing the hardware required for connections.

Refer to Chapter 2, Installing the Modem, for instructions on installing and cabling a modem for use with Motorola’s Network Management Systems.

Restoring Data Transmission

For critical leased line applications that require backup, you can use Models 3261, 3263, 3266, or 3268 in a point-to-point configuration. If the leased line fails, these modems can automaticall y reroute dat a traf fi c through the public swit ched teleph one network (PSTN) over a 2-wire dial line. This integral dial line restoral feature guarantees that data will keep flowing, minimizing network downtime.

ITU-T V.34 Compliant Modulation Mode

326XFAST and 326XFAST-SDC modems support the ITU-T V.34 compliant modulation mode. 326XFAST- SDC modems offer the same broad set of features

available in the 326XFAST modems, and let you take advantage of faster transmission speeds while providing highly reliable data transmission in full-duplex synchronous environments.

326XFAST modems have a line probing featu re tha t opt imizes perfo rmance o n ever y connection by automatically choosing the optimum bandwidth, carrier frequency, and data rate.

V.34 Modulation Mode Characteristics

V.34 modulation mode characteristics are as follows.

1-6 About the Modem

Data Rate: 2.4, 4.8, 7.2, 9.6, 12.0, 14.4, 16.8, 19.2, 21.6, 24.0, 26.4, 28.8, 31.2, and

33.6 kbps Baud Rate: 2400, 2743, 3000, 3200, and 3429. Some baud rates do not support all

data rates. Carrier Frequency: 1600, 1646, 1800, 1829, 1920, 1959, and 2000 Hz. Some baud

rates do not support all carrier frequencies. Modulation: V.34 is a four-dimensional trellis-coded modulation standard that uses

precoding and pre-emphasis equalization schemes.

Compatibility in V.34 Modulation Mode

326XFAST Series Modems (operating in V.34 Auto modulation mode), are compatible with modems that do not support the V.34 modulation mode, by automatically negotiating the highest common modulation mode (e.g., V.32bis).

V.90 Compatibility: Release 8.1 software enables 326X modems to operate with V.90 modems in dial-up connection s. With this softwar e, 326X modems can communicate with V.90 modems and negotiate V.34 rates. The release does not provide 56kbps rates for 326X modems, nor 326X rates higher than the V.34 33.6 kbps standard. An upgrade to 8.1 is not required for modems used only in leased-line applications.

About the

Modem

Synchronous Data Compression (SDC) Feature

The 326XFAST Series Modem is available in a synchronous data compression (SDC) model. 326XFAST products offer all the features of the 326XFAST family, plus synchronous DTE rates at 72.0 kbps or higher.

The 326XFAST-SDC Modem is an ideal alternative to costly digital services. Whether your application requires dedicated bandwidth, bandwidth on demand, synchronous dial-up, or dial backup, the 326X-SDC provides optimum throughput for all HDLC/SDLC-like environments, such as X.25, Systems Networking Architectu re (SNA), Statistical Multiplexer, and Router networks.

Refer to Chapter 4, Configuring the Modem, for d etails. The synchronous data compression feature in the 326XFAST-SDC Modem is

Motorola propriet ar y techn ology.

Automode/Multimode Feature

Using Automode/Multimode, the modem can automatically negotiate the highest common modulation speed (within a modulation mode) with another modem.

About the Modem 1-7

Remote Configuration

Using the local front pa nel, an NMS, or l ocal- modem AT ACU, you can configure a

Modem

About the

remote modem. You can also read the remote modem’s status snapshots and receive its configuration summary on a front panel or async terminal.

Error Correction and Data Compression

The modem provides error correction and data compression in accordance with the V.42 and V.42bis ITU-TS recommendation. With V.42, modems automatically determine whether to use Microcom Networking Protocol (MNP) Level 4 or Link Access Procedure for Modems (LAPM) for error correction. Depending on the scheme negotiated, the modem uses MNP Level 5 or V.42bis data compression. The SDC modem uses LAPM with a Motorola proprietary data compression technology.

Security

The modem provides access security at two levels:

• Front panel

• Modem access

Front panel security lets you password-protect a modem from access by other users. This prevents unaut horize d chang es fr om bein g made to a confi gurat ion. Fr ont panel security does not prevent you from using the modem.

You can also screen incoming calls so that unauthorized users cannot access a modem. This is accomplished with password and callback functions.

Appendix A explains how to configure security features.

Status Snapshots

The modem’s status snapshot feature lets you view a local or remotely controlled modem's EIA signals and Motorola circuit quality monitoring system (CQMS) parameters, and view a configuration summary.

CQMS paramete rs continuously estimate major line parameters without disrupting data traf fic. Measur ement o f such se lections as signa l-to-no ise r atio and receive level helps you to isolate causes of degraded network performance.

1-8 About the Modem

Adaptive Rate System

With the Adaptive Rate System enabled, the 326X Series Modem continuously optimizes its transmit speed within the V.34, V.32bis, V.32 (coded and uncoded), and V.22bis modulation modes. By constantly monitoring signal quality, the modem adapts to the optimum transmission rate allowed by line conditions, ensuring maximum throughput and efficiency.

Troubleshooting (V.54 and V.22bis Tests)

The modem supports a full range of ITU-TS V.54 and V.22bis compatible tests to help isolate and correct problems.

Refer to Chapter 6 for typica l problems and ways to correct them. Cha pter 6 also lists the supported diagnostic tests, and instructions for initiating and terminating tests using either the front panel control keys or AT commands.

For details on tests, refer to Chapter 4 of the 326X Series Modem Reference Guide.

Introduction

This chapter has three parts:

• System Requirements for Software Upgrades

• Configuring and Operating the Modem

• Other Call Establishment Methods

System Requirements for Software Upgrades

This section explains the prerequisites for an upgrade to 7.9 software. This section does not apply to new units with 7.8 or higher software installed.

Getting Started

A modem can be upgraded to Release 7.9 software only if it has Releas e 7.0, 7.5, 7.6, or 7.7 software.

Configuring and Operating the Modem

You can configure and operate the modem in several ways:

•From the modem front panel

•From a Network Management System (NMS)

•From the modem AT Automatic Calling Unit (ACU), if it is attached to an

asynchronous “dumb” terminal—a terminal without software—or to a PC

running an asynchronous communications software package

Each of these is described in the sections that follow.

If You Are Unsure of Your DTE’s Data Format...

The DTE manual should tell you what data f ormat—a synchr onous or synchro nous — it uses. Most PC applications use an asynchronous data format.

Using the Front Panel

You can configure and operate all modem functions using the front panel’s:

3-2 Getting Started

• Light-emitting diodes (LEDs)

• Liquid crystal display (LCD)

• Configuration menus

• Control keys

Figures 3-1 and 3-2 show the stand-alone modem front panel. Figure 3-3 shows the enclosure card front panel. Note the LCD, LEDs, and control keys.

NOTE: Information specifi c to enclos ure card modems is covered in the addendum, 326X Series Modem Cards, shipped with the modem backplane.

IMPORTANT: To use the front panel keys, the modem must be connected to an AC power source, the rear panel power switch must be turned on, and rear panel DIP Switches #3 and #6 must be set to the Off (up) position. See Chapter 2 for details.

Front Panel Display

The front panel has a 16-character alphanumeric LCD display (see Figure 3-2 or 3-3). You access the configuration menu tree through this display, to:

• Configure the modem

• Store and view telephone numbers

• Initiate and answer calls

• View status information

• Run online tests

• Enter passwords and network addresses

3-4 Getting Started

Navigating the Configuration Menu Tree

This section describes the modem menu tree structure. It explains how to access parameters using the front panel control keys.

Menu Structure

The menu structure consists of fifteen categories, which appear in capital letters.

Example: CONFIGURATION OPT’S. Each category has parameters (example: Mode). Some parameters are

configurable; others indicate modem and call status. Most parameters have selectable options. Options affect the modem’s operating characteristics.

You can view parameters and options in the front panel LCD display. If options can be set, the following indicators display:

• An equals sign (=) indicates the currently selected option of the parameter

• A colon (:) indicates that the displayed option is available but is not selected

Each parameter has a default option:

• Some defaults are determined by the assigned factory-preset option sets (preconfigured option sets). These defaults are exclusive to an option set.

• Other factory options are not exclusive to an option set and they always have the same default setting, regardless of which factory-preset option set you use.

Refer to Appendix A, Figure A-1, or to the Refer ence Card to see the complete menu tree structure, including the available and default options.

Setting Configuration Options from the Front Panel

The four contr ol keys (Figures 3-2 and 3-3) let you access parameters and options. Table 3-2 describes control key functions.

or after the modem has “timed-out” (i.e., the front panel control keys have not been used for at least five minutes). The data rate (9600, in the display Data 9600 T/D?) is the current DCE (modem-to-modem) data rate. It varies with the speed at which the modems connect. The Data 9600 T/D? category serves three primary functions:

• Talk/Data” Switch

• Operating Status Displays

• Option Sets/Dialing Options

Talk/Data Switch

Pressing when Data 9600 T/D? is displayed toggles the modem between using:

• An external telephone to manually dial a telephone call

• The modem to dial a stored or unstored telephone number

3-6 Getting Started

Operating Status Displays

The DTE19.2 RELIABL and Phase Jitter subcategories let you view modem operating status. Example: in the DTE 19.2 RELIABL subcategory, pressing displays:

• Operating status messages

• DTE/DCE rat e/status

• Error correction/data compression status

• EIA/TIA signal status

• Disconnect reasons

• The modem’s software revision level

• Circuit Quality Monitoring System (CQMS) paramete r status

For details, refer to Appendix A. For details on status displays, refer to Chapter 1, AT Commands, of the 326X Series Modem Reference Guide.

• Appendix A for brief descriptions of parameter options and features

•The 326X Series Modem Reference Guide for detailed descriptions of parameter options and features

Getting Started 3-7

Using the AT Automatic Calling Unit (ACU)

ATZ4

To connect the modem to an asynchronous terminal—a terminal without software—or a PC running an asynchr onous communicati ons softwar e package, you use the modem’s AT Automatic Calling Unit (ACU) interface.

The AT ACU is compatible with:

•The industry-standard AT command set (AT and AT& commands)

• The Motorola enhanced AT command set (AT

AT commands define how the modem is configured, how it makes calls, and what test operations it performs. The AT command set lets you configure and operate modem options and features from the PC or asynchronous terminal keyboard.

Getting Started

Using the Modem with an Async Terminal

If you are connecting the modem to an asynchronous terminal, you can use the AT ACU to configure parameter options from the keyboard. Learn the AT command syntax in order to generate the appropriate AT commands.

Where Do I Go from Here?

To continue configuring the modem from an asynchronous terminal, refer to:

• Chapter 4 for configuration instructions.

• Chapter 5 to learn AT command syntax.

• Chapter 6 for a discussion of common problems and how to correct them.

• Appendix A to change configuration options. The Reference Card shows the complete menu structure.

commands)

3-8 Getting Started

Using the Modem with a PC and Async Communications

Software

When using the modem with a PC, you need communications or terminal emulation

software. Communications software acts as an interface—with pull-down menus or graphics—between your PC and modem, allowing you to perform modem operations from your PC.

It is unlikely that you will use AT commands directly to configure and test the modem. Some communications software, however, may not support all of the modem’ s configu ration optio ns or may requi re you to iss ue commands to th e modem directly.

Communications software packages that directly support the modem (where Codex 3260 Modem or Motorola 3260 Modem is a selection within the package) support the industry standard commands (AT, AT&) and the Motorola-enhanced commands

), making more knowledge of AT command syntax unnecessary.

Getting Started 3-9

Other Call Establishment Methods

In addition to the configuration and operation methods in this chapter, the modem supports other methods to establish and manage telephone connections:

• V.25bis ACU (for synchronous or asynchronous applications)

• NetView LPDA-2 ACU (for synchronous applications)

• IBM AS 400 (for synchronous dialing)

• External Auto-Call Units such as the Bell 801C

These methods are described in the sections that follow.

V.25bis ACU for Sync or Async Applications

Getting Started

The modem supports an ITU-TS V.25bis ACU for initiating calls fr om an int el li gen t terminal, in synchronous or asynchronous formats, which supports:

• Addressed mode, to perform call-related tasks, such as storing phone numbers in memory, dialing calls from memory, connecting/disregarding incoming calls

• Manual and direct call establishment methods. Direct mode lets you use DTR transitions from the DTE to establish calls. Manual mode lets you manually initiate and answer calls with a telephone and then transfer the call to the modem.

Where Do I Go from Here?

For more information on the V.25bis ACU, refer to Chapter 3, Automatic Calling Interfaces, in the 326X Series Modem Reference Guide. Programmers and System Developers should also refer to Chapter 3 for a programming guide describing asynchronous and synchronous data formats using the ASCII/EBCDIC character sets.

NetView LPDA-2 ACU for Sync Applications

The modem supports Link Problem Determination Aid (LPDA-2). LPDA-2 is the communications protocol between IBM host software and transmission devices for exchanging diagnosti c and control information. LPDA-2 commands provide a means for an attached terminal to command the modem to dial a telephone number and report back if the call is successful or not successful.

Where Do I Go from Here?

For more information on using the LPDA-2 ACU, refer to Chapter 3, Automatic Calling Inte rfaces, in the 326X Series Modem Reference Guide for configuration information and for information on NetView’s LPDA-2 dialing commands.

3-10 Getting Started

Sync Dialing from an IBM AS 400

The modem can be configured to operate as a synchronous originate modem with the IBM AS 400. The AS 400 supports switched operation with call origination via a V.25bis-compliant call establishment driver. In this type of application, the modem is driven by the APPC/APPN bit-synchronous protocol.

Where Do I Go from Here?

For more information on using the modem with an IBM AS 400, refer to:

• Chapter 4 for configuration instructions.

• Chapter 3, Automatic Calling Interfaces, in the 326X Series Modem Reference Guide for details on bit-synchronous protocol frame formats and the V.25bis protocol.

External Auto-Call Units

The modem can be used with applications that support external dialers, such as the Bell 801C. Once an external dialer establishes a call, it passes control of the dial line to the mo dem by the MI/MIC cont rol leads on the DIAL LIN E connector. NOTE: This type of application is supported in Canada and the U.S.A. only.
