About the Modem

Introduction

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 (AT*MX) and Min Rate (AT*MN) parameter options are within the valid range 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 Telenetics-enhanced (AT*) 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 establishment methods, such as V.25bis or LPDA2 automatic call units (ACUs)

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

326X V.34, V.32bis Series, V.34-SDC specifications

Telenetics has been a key player in the field of telecommunications, offering advanced modem solutions that cater to diverse communication needs. Among their notable products are the V.34-SDC and V.32bis series, including the 326X V.34 modem. These modems have been designed to enhance data transmission reliability and speed in various applications.

The Telenetics V.34-SDC modem represents a significant leap in technology, supporting data rates of up to 28.8 Kbps. This modem utilizes the advanced V.34 modulation scheme, which optimizes the use of existing telephone lines to deliver impressive performance, especially for users requiring high-speed data transmission. The V.34-SDC model also features robust error correction and data compression techniques, ensuring that users receive accurate data even over less than ideal connections. With its extended line-conditioning capabilities, the V.34-SDC modem can efficiently handle long distances and poor line conditions.

Equally noteworthy is the V.32bis series, which provides backward compatibility with V.32 modems, enabling seamless integration into existing systems. Capable of speeds up to 14.4 Kbps, the V.32bis modems are ideal for businesses and environments where legacy systems remain in use. It features adaptive equalization and advanced echo cancellation, ensuring a clear signal is maintained throughout the data transmission process. This versatility allows users to connect with various devices across different infrastructures.

The 326X V.34 modem further exemplifies Telenetics' commitment to high performance. It combines the V.34 capabilities with enhanced security features, offering users encryption options for sensitive data. This is particularly crucial for businesses that need to safeguard their information against potential vulnerabilities during transmission. The 326X also supports various data communication protocols, making it adaptable for multiple platforms and applications.

In summary, Telenetics’ V.34-SDC, V.32bis series, and 326X V.34 modems stand out for their high-speed data transmission, compatibility, advanced error correction, and security features. These technologies make them excellent choices for both enterprise and networking applications where reliable communication is vital. Telenetics continues to innovate, delivering modem solutions that meet the evolving demands of the telecommunications landscape.
