Modulation in which the time interval separating any two significant instants is equal to the unit interval or a multiple of the unit interval.

A signal in which the time interval separating any two significant instants is equal to the unit interval or a multiple of the unit interval.
Note 1: Variations in the time intervals are constrained within specified limits.
Note 2: "Isochronous" is a characteristic, while "synchronous" indicates a relationship.

To restrict communication in both directions with a participant of the conference. [T1.647-1995]

Synonym isolated ground plane.

A set of interconnected frames that is intentionally grounded via only one connection to a ground reference; this plane, taken as a conductive unit with all of its metallic surfaces and grounding (earthing) wires bonded together, is insulated from contact with any other grounded metalwork in the building. Synonym isolated bonding network. [T1.313-1997]

A single bit period of logical value "1" with adjacent bit periods of logical value "0". [T1.106-1988]

A pulse free from the effects of the other pulses in the same signal. (A suitable testing signal is a repetitive pattern of one "one" and seven "zeros". ) [T1.408-1990]

Any bit period of logical value "
1. " [T1.106-1988]

1. Pertaining to a material with properties, such as density, electrical conductivity, electric permittivity, magnetic permeability, or refractive index that do not vary with distance or direction.
2. Pertaining to a material with magnetic, electrical, or electromagnetic properties that do not vary with the direction of static or propagating magnetic, electrical, or electromagnetic fields within the material.
