Appendix C - V.90 Information

This appendix provides information on ITU V.90 support for the Multi-Tech MT5600ZDX modem. It lists some of the differences in the ITU-T V.90 code compared to the K56flex only code.

V.90 Support

V.90 is the ITU designation for what had formerly been called V.pcm. The ITU recommendation V.90 was determined at a meeting in Geneva ending February 6, 1998. The current draft revision date is 2/4/98; it is expected to be ratified later in 1998.

V.90 will replace K56flex and other proprietary solutions for PCM connections. Dual-mode client modem code will be important until all central-site digital modems are upgraded to V.90 and all interoperability problems have been resolved. Until that time, the Dual-mode client code will provide reliable connections in K56flex mode to the central- site modems currently deployed.

Your V.90 dual-mode (V.90/K56flex) modem now includes: ·New AT commands (+MS=12, AT!),

·New Result Codes in V.90 mode, and

·A-law/u-law selection (+MS parameter 5), and various changes to the AT command documentation.

These new functions are explained in documents that are readily-available on the Multi-Tech web site in Portable Document Format (PDF) files at http://www.multitech.com/support/manuals/IDCfiles/ manuals.idc . You can download the Acrobat Reader to view PDF files (you may want to bookmark http://www.adobe.com/prodindex/ acrobat/readstep.html before following the “download” link).

MT5600ZDXV, MT5600ZDX specifications

The MultiTech MT5600ZDX and MT5600ZDXV are state-of-the-art modems designed to offer reliable communication capabilities for a variety of applications. These devices are particularly favored in industrial, telecommunications, and enterprise settings due to their robust performance and versatility.

One of the standout features of the MT5600ZDX series is its ability to support both analog and digital signaling. This dual compatibility enables seamless integration with existing telecommunication infrastructure, making it an ideal choice for businesses looking to upgrade without overhauling their entire system. With ITU-T V.34 modem technology, these devices support high-speed data transmission rates of up to 56 kbps, ensuring quick and efficient data transfer.

The MT5600ZDX and MT5600ZDXV models come equipped with a comprehensive array of communication protocols, including PPP, TCP/IP, and the unique Multitech proprietary protocols. This broad compatibility allows for easy connection to various networks and devices, facilitating smooth data exchange across platforms.

Another notable feature is the built-in error correction and data compression capabilities. With technologies such as MNP, V.42, and V.42bis, users can expect enhanced data integrity and faster transmission speeds, which are particularly crucial in environments with high noise levels or signal interference. These features make the modems highly effective for remote monitoring applications, telemetry, and point-of-sale terminals.

Additionally, both models excel in terms of connectivity options. The MT5600ZDX includes a standard RS-232 interface, while the MT5600ZDXV offers an enhanced V.24 interface for those requiring additional communication flexibility. This variety in connectivity options ensures that users can integrate these devices into a wide range of systems, whether for industrial automation or remote data acquisition.

Durability and reliability are also core characteristics of the MT5600ZDX series. Designed to operate in challenging environments, they boast a wide operating temperature range and robust casing, making them suitable for deployment in harsh industrial conditions.

In conclusion, the MultiTech MT5600ZDX and MT5600ZDXV modems provide a feature-rich solution for organizations seeking high-performance communication. With advanced technologies, exceptional versatility in connections, and reliability in demanding settings, they continue to stand out as preferred choices for efficient industrial communication solutions. These devices not only enhance operational efficiency but also pave the way for future-proof connectivity in an increasingly digital world.
