VIDEOCONFERENCING (V.80) SUPPORT

The Communicator V.90 supports IT-U V.80 recommendations. This feature ensures compatibility with host-based H.324 videoconferencing application software. The INTEL / AMBIENT MD56xx chipsets support both transparent and framed submodes of the V.80 synchronous access mode.

POWER MANAGEMENT MODES

The Cirrus/Ambient chipset provide sleep mode to reduce power consumption when the modem inactive. In operational mode, the modem chipset is fully powered and is either communicating with the host and/or another modem or is performing internal processing.

The modem is considered to be in an inactive state when:

1.No internal processing is being performed.

2.No activity occurs between the host and the modem within a specific time.

3.The modem is on-hook.

The mode exits sleep mode whenever the host writes the modem or when a ring signal is detected.

CALLER ID

Caller ID is a service that allows the called party know the caller’s telephone number before the call is answered. The information transmitted to the called party via Caller ID includes the call date, the call time, and the call number. This service is not available everywhere due to Central Office telephone equipment limitations and legal prohibition in some locations. Subscription for this service is usually available at a small monthly fee.

For more information on how to use this feature, please refer to the communication software user’s guide.

V.90 specifications

The Jaton V.90 modem is a classic example of 56K technology that revolutionized dial-up internet connections in the late 1990s. As one of the early models supporting the V.90 standard, this modem enabled users to experience faster internet speeds compared to its predecessors. The V.90 protocol allowed for a maximum download speed of 56 Kbps, offering significant improvements over the previous V.34 modem, which capped out at 33.6 Kbps.

One of the standout features of the Jaton V.90 is its ability to adapt to different line conditions, ensuring optimal performance regardless of the quality of the telephone line. The V.90 standard provided a retransmission mechanism that allowed data to be resent if errors occurred during transmission, improving reliability and reducing the likelihood of dropped connections.

The modem incorporates technologies such as error correction and data compression. With built-in error correction protocols like V.42 and MNP, the Jaton V.90 can detect and correct common transmission errors, which is vital in maintaining a stable connection. The data compression technology, which uses MNP Class 5, enhances throughput by compressing data before transmission. As a result, users could effectively increase their upload speeds and minimize latency, creating a more seamless browsing experience.

The hardware features of the Jaton V.90 modem typically include a standard RJ-11 telephone connector, which makes it easy to connect to existing phone lines. The modem may come with both internal and external configurations, allowing flexibility depending on user preferences and system requirements. The external version often features indicator LEDs that provide real-time feedback on connection status, data transfer activity, and power status.

Compatibility is another crucial aspect of the Jaton V.90 modem. Operating with a variety of systems, it was designed to work with Windows, Mac OS, and other operating environments, making it accessible for a wide range of users. Additionally, the modem generally supports various software applications for easy configuration and management.

Ultimately, the Jaton V.90 modem played a pivotal role in facilitating internet access during a transformative period, laying the groundwork for future high-speed connections. While modern broadband solutions have since eclipsed dial-up speeds, the legacy of the Jaton V.90 as a reliable and innovative piece of technology remains significant in the history of internet connectivity.
