Overview

The COMSPHERE 3800 Series modems, a new generation of full-feature, high-speed dial modems, offer reliable asynchronous and synchronous operation over dial- or leased-lines networks. The 3800 Series modems' unique software defineability allows for the addition of future enhancements, whether it is installing new features or firmware upgrades.

Through its downloading capability, any 3800 Series modem 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 data rates as high as 19,200 bps (V.32terbo) over dial lines is guaranteed by employing the latest techniques in CCITT V.42bis/MNP Class 5 data compression and CCITT V.42/MNP error correction. In addition to fast line speeds, the modem can send data to the DTE at speeds as high as 115,200 bps.

The 3800 Series modem is extremely versatile when used in modem pooling environments; it allows multiple users to temporarily customize settings in the 3800 Series modem, thereby permitting communication with the calling modem. Upon disconnection, the 3800 Series 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, EIA RS-366-A dialing for carrier-mounted modems, and the user-friendly diagnostic control panel (DCP), permits the 3800 Series modem to be used in a variety of applications and environments while also allowing control over modem configuration, dialing, and diagnostics. The 3800 Series modems offer four preset factory configurations containing the most often used modem settings. These factory presets provide quick configuration for any asynchronous/ synchronous dial, synchronous leased, or UNIXr hardware-based dial environments.

The 3800 Series family is available in three models: the Model 3810, a 4-wire/2-wire standalone modem; the Model 3811, a carrier- mounted version of the standalone unit; and the Model 3820, a 2-wire standalone unit. All three models offer a variety of modulation schemes and network enhancements while still providing reliable, high-speed data transmission using the latest in modem technology.
