PSTN

This protocol (Microcom Networking Protocol) detects and corrects data errors caused by telephone line noise and signal distortion. MNP5 includes data compression.

(Modulator/DEModulator). A device that transforms signals from digital to analog form and vice versa.

The process of varying some characteristics (usually amplitude, frequency, and/or phase) of a carrier wave to form data transmissions.

A communications circuit.

The customer-assigned diagnostic address of a tributary modem.

Network Interface Module. The interface provided, up to two per carrier, for the public switched telephone network (PSTN) used by Model 3811 dial modems.

Network Management System. A set of diagnostic and configuration management tools for a data communication network, consisting of software programs and dedicated computer hardware.

A telephone or modem is being used.

A telephone or modem is not being used.

The modem is in a state where it is ready to transmit a call. In a dial network, it is the modem that makes the call. In a leased-line network, it is one of two sides of the network that is selected to be the originating modem.

A way of checking data accuracy by counting the number of bits that have a value of one.

Telephone switching equipment (Private Branch Exchange) dedicated to one customer. A PBX connects private telephones to each other and to the public dial network.

A dial modem operating mode characterized by a fixed output power level of –9 dBm. It is one of two possible modes of operation for modems connected to dial lines (see programmable interface).

The diagnostic address of a control modem derived from its location in the carrier: its carrier and slot number.

A test that checks most hardware components when the modem is powered-on.

A three-digit code indicating the modem’s highest VF data rate.

A dial modem operating mode characterized by an output power level (–12 to 0 dBm) set by a programming resistor in the jack. It is one of two possible modes of operation for modems connected to dial lines (see permissive interface).

The rules for timing, format, error control, and flow control during data transmission.

Public Switched Telephone Network. A network shared among many users who can use telephones to establish connections between two points. Also known as dial network.
