COMSPHERE 3800 Series Models
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 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 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, 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
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.
