A standard for modems operating full-duplex with asynchronous or synchronous data at 1200 bps over the dial network (PSTN).

A standard for modems operating full-duplex with asynchronous or synchronous data at 1200 or 2400 bps over the dial network (PSTN).

A fax communications standard for modems operating half-duplex with synchronous data at 2400 and 4800 bps.

A fax communications standard for modems operating half-duplex with synchronous data at 7200 and 9600 bps.

A standard for modems operating full-duplex with asynchronous or synchronous data at 4800 or 9600 bps on switched (dial) or leased telephone lines.

A standard for modems operating full-duplex with asynchronous or synchronous data over dial networks (PSTN) or leased lines at 14,400, 12,000, 9600, 7200, or 4800 bps.

ITU-T standard for error control protocol.

ITU-T standard for data compression.

ITU-T standard for local and remote diagnostic loopback tests.

A jack used for leased-line networks. Pins 1 and 2 are the transmit pair and Pins 7 and 8 are the receive pair.

A set of seven keys surrounding the DCP’s LCD. These keys are used to select configuration options and to maneuver through the DCP.

Liquid Crystal Display. A thin sandwich of two sealed glass plates containing liquid crystal material. When voltage is applied, the amount of light able to pass through the glass plates is altered so that messages may be ‘‘written” on the display.

A private line connection exclusively for the user. No dialing is necessary.

Light-Emitting Diode. A light or status indicator on the DCP that glows in response to the presence of a certain condition (e.g., Alrm).

The modem’s transmit VF signal is looped to its receiver.

A disconnect can occur if the modem receives an extended space from a remote modem; for example, when a remote modem is commanded to disconnect, it transmits a continuous space to the modem before disconnecting.

Any test that verifies a device’s integrity by connecting the device’s output of one direction to the device’s input of the other direction, then checking the received signal for errors.

Line Signal Detect. A signal between the DTE and modem indicating energy exists on the transmission circuit.

The structure containing the 3800 Series menu hierarchy starting at a Top-Level menu and extending down to various modem functions.
