Overview
The Model 3830 modem is a member of the COMSPHEREr
3800 Series Modem product line. The Model 3830 modem is a
high-speed dial modem that offers reliable asynchronous and
synchronous operation over dial- or two-wire leased-line networks. The
Model 3830’s software definability allows you to add enhancements
and new features as they become available, with no further investment
in hardware, no on-site personnel, and minimal downtime.
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 ITU-T V.42bis/MNP Class 5 data compression and
ITU-T 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 Model 3830 modem is extremely versatile when used in modem
pooling environments; it allows multiple users to temporarily
customize settings in the Model 3830, thereby permitting
communication with the calling modem. Upon disconnection, the
Model 3830 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 and ITU-T V.25bis
dialing, permits the Model 3830 to be used in a variety of applications
and environments while also allowing control over modem
configuration, dialing, and diagnostics. The modem offers two preset
factory configurations containing the most often used modem settings.
These factory presets provide quick configuration for any
asynchronous or UNIX hardware-based dial environment.
