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.

Lightning

Warning

All Motorola devices should be used in en vir onments designed for computers and electronic equipment. In areas susceptible to lightning, take precautions to prevent damage to electronic equipment. Contact your telephone company, or an electronic accessories vendor, f or i nf o rma ti on on li ght ni ng protection equipme nt. Customers experiencing problems caused by surges from lightning have eliminated such problems by installing appropriate surge suppressors on power and data lines connected to Motorola devices.

Avertissement

Tous les dispositifs Motorola doivent être utilisés dans des environnements conçus pour des ordinateurs et du matériel électronique. Dans les zones susceptibles d’être frappées par la foudre, prenez des précautions pour éviter que le matéri el électron ique soit endommagé. Contactez votre compagnie téléphonique, ou un vendeur d’accessoires électroniques, pour obtenir des renseignements concernant les systèmes de protection contre la foudre. Certains usagers confrontés à des problèmes causés par des sautes de tension dues à la foudre ont éliminé ces problèmes en installant des régulateurs de tension appropriés sur les câbles électriques et les câbles de données reliés aux dispositifs Motorola.

Warnung

Motorola-Geräte sind grundsätzlich in für Rechner und elektronische Anlagen vorgesehenen Umgebungen zu verwenden. In unwettergefährdeten Bereichen ist jegliche Elektronik gegen Blitzeinwirkung zu schützen. Näheres über entsprechende Schutzeinrichtungen erfahren Sie von Ihrer Telefongesellschaft oder einem Elektrohändler. Probleme mit Spannungsstößen durch Blitzeinwirkung lass en sic h durch Ei nbau von Überspa nnungsab leitern in die zu Motorola-Geräten führenden Netz- und Datenleitungen beheben.

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.

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.
