Overview
The COMSPHERE 3800 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 is guaranteed by employing the latest techniques in CCITT V 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 1

Series modems, a new
.32terbo) over dial lines
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 A 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 381 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.

The telephone company provides the line termination jacks for the type of service you request. Y to operate in either Permissive or Programmable mode. Advance coordination with the telephone company is suggested when connecting the modem to telephone dial lines (PSTN).
If you operate in the Permissive mode, the modem’s transmit output level is fixed at approximately –9 dBm. The telephone company assumes that the line loss is 3 dBm and no compensation is provided for additional losses. The resulting level at the telephone central of could be lower than the nominal –12 dBm provided with Programmable mode. A Permissive mode telephone line is usually terminated with a USOC RJ1
If you operate in the Programmable mode, the telephone company installs a program resistor that adjusts the modem’ telephone company’s central office is at the maximum allowable level of –12 dBm. Telephone lines for the Programmable mode are usually terminated with a USOC RJ45S jack or an RJ41S jack switched to Programmable.
