Caution

Ensure that the electrical interfaces of the equipment you connect to the modem are compatible. Incompatible interfaces may seriously damage the modem. Telenetics makes no guarantee of the equipment’s integrity if you do not ensure that compatible interfaces are used. If your DTE has a different interface, you will need an external converter cable.

326X Series Modems have an EIA/TIA-232/EIA/TIA-562 electrical interface for connection to external equipment. For compatibility with DTEs that have a V.35 interface, the V.34-SDC Modem is also available with the optional ITU-TS V.35 Recommendation electrical interface.

The rear-panel DTE port is configured at the factory for either interface. Both interfaces are not available in a unit. Regardless of the interface, external DTEs are connected through the modem’s rear-panel DTE port.

NOTE: When operating with the V.35 interface, DIP switch S1 must be set to the off (up) position (see Figure 2-2or 2-3).

To purchase a compatible cable, consult Appendi xB.

Operating at V.34 DTE Rates

To operate V.34 or V.34-SDC modems at DTE rates greater than 19.2 kbps, you must use cables that can handle the higher data rates. Refer to Appendix B for instructions on determining the correct cables to use.

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.
