Overview

The COMSPHEREr 3810Plus, 3820Plus, and

3811Plus modems, extensions of the award-winning COMSPHERE 3800 Series, are a new generation of full-feature, high-speed dial modems that offer reliable asynchronous and synchronous operation over dial- or leased-lines networks. The 3800Plus modems' software defineability allows for the addition of future enhancements and features.

Through their downloading capability, 3800Plus modems can be upgraded to the latest firmware, requiring no new hardware investment or on-site personnel, and little or no downtime. These modems support a wide range of modulation schemes and offer control using either AT commands, the user-friendly diagnostic control panel (DCP) or the optional COMSPHERE 6700 Series Network Management System (NMS). The NMS performs extensive monitoring, testing, reporting, and restoral functions to assist in managing your network.

High-speed data transfer and reliable throughput at line rates as high as 33,600 bps over dial lines is achieved by employing the latest techniques in CCITT V.42bis/MNP Class 5 data compression and CCITT V.42/MNP error correction. The modems can send data to the DTE at speeds as high as 115,200 bps.

The 3800Plus modem is extremely versatile when used in modem pooling environments; it allows multiple users to temporarily customize modem settings, thereby permitting communication with the calling modem. Upon disconnection, the 3800Plus modem falls back to its original configuration settings and resumes normal operation.

The modem's compatibility with a number of dialing methods and protocols, such as asynchronous AT commands, CCITT V.25bis dialing, and the user-friendly diagnostic control panel (DCP), permits the 3800Plus

modem to be used in a variety of applications and environments while also allowing control over modem configuration, dialing, and diagnostics. The 3800Plus modems offer preset factory configurations containing the most often used modem settings. These factory presets provide quick configuration for any asynchronous or synchronous dial, synchronous leased, UNIXr hardware-based dial, or cellular environments.

The 3810Plus is a 4-wire/2-wire standalone modem; the 3820Plus is a 2-wire standalone modem; the 3811Plus is a carrier-mounted version of the 3810Plus.
