Synonym conference call.

A series of data words specifying message type, message length, parameter message(s), and error detection information. The parameter message consists of one or more parameters. Each parameter is a series of data words specifying parameter type, parameter length, and parameter data. [T1.401-1998]

Frequency-shift keying (FSK) in which multiple codes are used in the transmission of digital signals.
Note: In MFSK, the coding schemes use multiple frequencies that are transmitted concurrently or sequentially.

1. In telephone systems, the connection of a terminal facility so that it can be served by one or several switching centers.
Note: Multiple homing may use a single directory number.
2. In telephone systems, the connection of a terminal facility to more than one switching center by separate access lines.
Note: Separate directory numbers are applicable to each switching… (Read More →)

Transmission media using more than one type of transmission path (e.g., optical fiber, radio, and copper wire) to deliver information.

A feature that enables the UPT user to simultaneously register multiple terminal addresses for incoming and/or outgoing UPT calls. [T1.701-1994]

In facsimile systems, scanning performed simultaneously by two or more scanning spots, each one analyzing its fraction of the total scanned area of the object.

See multiplexing.

In a time-division multiplexer, the bit rate that is equal to the sum of (a) the input channel data signaling rates available to the user and (b) the rate of the overhead bits required.

1. In frequency-division multiplexing, the frequency band occupied by the aggregate of the signals in the line interconnecting the multiplexing and radio or line equipment.
2. In frequency division multiplexed carrier systems, at the input to any stage of frequency translation, the frequency band occupied.
Note: For example, the output of a group multiplexer consists of a band of frequencies… (Read More →)
