multimedia communication system

A system that handles more than one media stream in a synchronized way from the user's point of view. The system may allow interconnection of multiple parties, multiple connections, and the addition or deletion of resources and users within a single communication session. [T1.80

multimode distortion

A distortion mechanism, occurring in multimode fibers, in which the signal is spread in time because the velocity of propagation of the optical signal is not the same for all modes.
Note 1:
In the ray-optics analogy, multimode distortion in a step-index optical fiber may be compared to multipath propagation of a radio signal. The direct signal is distorted by… (Read More →)

multimode optical fiber

An optical fiber that supports the propagation of more than one bound mode.
Note: A multimode optical fiber may be either a graded-index (GI) fiber or a step-index (SI) fiber.

multipath

The propagation phenomenon that results in radio signals' reaching the receiving antenna by two or more paths.
Note 1: Causes of multipath include atmospheric ducting, ionospheric reflection and refraction, and reflection from terrestrial objects, such as mountains and buildings.
Note 2: The effects of multipath include constructive and destructive interference, and phase shifting of the signal.
Note 3: In facsimile… (Read More →)

multiple

A system of wiring so arranged that a circuit, a line, or a group of lines is accessible at a number of points. Synonym multipoint.

multiple access

1. The connection of a user to two or more switching centers by separate access lines using a single message routing indicator or telephone number.
2. In satellite communications, the capability of a communications satellite to function as a portion of a communications link between more than one pair of satellite terminals concurrently.
Note: The three types of multiple access… (Read More →)
