COMSPHERE 3800 Series Modems
3810-A1-001, 3811-B1-001, 3820-A1-001
Software-Defined (SD) V.32bis Modem Family
Overview
The COMSPHERE 3800 Series Software-Defined (SD) modem family consists of a number of full-featured V.32bis modems that support a wide variety of modulation schemes and functionality in both dial and 2/4-wire leased-line applications. By employing the latest techniques in ITU-T V.42bis/MNP Class 5 data compression and V.42/MNP 4 error correction, these modems offer error-free, high-speed data transfer and reliable throughput at data rates as high as 19,200 bps (V.32terbo) over dial/leased lines and can send data to the DTE at speeds as high as 115,200 bps.
The modem’s compatibility with a number of dialing methods and protocols, such as asynchronous AT commands, ITU-T V.25bis dialing, EIA RS-366-A dialing for carrier-mounted modems, and the user-friendly diagnostic control panel (DCP), permits the 3800 Series modems 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 UNIX hardware-based dial environments.
The COMSPHERE 3800 Series Software-Defined (SD) modem family is based on Zhone’s award winning architecture that allows new features and enhancements to be downloaded over the public telephone lines. Through its software 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.
The COMSPHERE 3800 Series modems are available in several models.
• Model 3810: Standalone unit capable of operation on either 2-wire dial or 2/4-wire leased lines.
• Model 3811: Carrier-mounted modem for installation into a COMSPHERE 3000 Series Carrier; it is capable of operation on either 2-wire dial or 2/4-wire leased lines.
• Model 3820: Standalone unit capable of operation on either 2-wire dial or 2-wire leased lines.
COMSPHERE 3800 Software-Defined (SD) modems offer an innovative solution to reliable, high-speed network requirements by ensuring optimal error-free communications for your business’ critical data. The COMSPHERE 3800 SD modems incorporate a flexible, state-of-the-art architecture that meets a wide variety of data communications requirements including both high-speed dial and two- or four-wire leased-line applications. With a unique software-defined architecture, the COMSPHERE 3800 SD family provides the high performance and unmatched reliability that users have come to expect from Zhone.
