Overview

The COMSPHERE 392xPlus modems are full-feature, high-speed leased modems, providing

reliable asynchronous and synchronous operation over leased- or dial-line networks with data rates

as high as 33,600 bps.

Through downloading capability, any 392xPlus modem is upgradable to the latest firmware,

requiring no new hardware investment or on-site personnel, with little or no downtime (refer to

Chapter 3, DCP Operation, for more information regarding downloading options). The 392xPlus

modems support a wide range of modulation schemes and offer control using either AT commands,

the diagnostic control panel (DCP), or the optional COMSPHERE 6700 and 6800 Series Network

Management Systems (NMS). The NMS performs extensive monitoring, testing, reporting, and

restoral functions to assist in managing your network.

The 392xPlus modems are compatible with a number of dialing methods and protocols, such as

asynchronous AT commands, ITU-T V.25bis dialing, and the DCP. The DCP allows you to use the

392xPlus modem in a variety of applications and environments while also providing control over

modem configuration, dialing, and diagnostics. The 392xPlus modems come with preset factory

configurations that are the most often used modem settings.
