Pertaining to software that will run on more than one operating system (i.e., on more than one platform).

The operation of two transmitters on the same frequency, but with polarizations in the opposite sense, e.g., plane polarization with one transmitter-receiver pair being vertically polarized and the other pair horizontally polarized.

In a satellite communications system, the signal power and control connections between the components of an Earth station.
Note: Examples of cross-site links are (a) links between transmitters and antennas and (b) links between control consoles and transmitters.

A switch that has a plurality of vertical paths, a plurality of horizontal paths, and electromagnetic means, i.e., relays, for interconnecting any one of the vertical paths to any one of the horizontal paths.

1. In audio programming, recording, or mixing, to combine signals in such a manner that one channel or source fades out as another fades in, while maintaining an essentially constant program volume.
2. The result produced thereby.

A data link between two satellites.

A single element that (a) is in the array of elements that compose a switch and (b) consists of a set of physical or logical contacts that operate together to extend the speech and signaling channels in a switched network.

1. Undesired coupling of a signal from one circuit, part of a circuit, or channel, to another.
2. Any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel.
Note 1: In telephony, crosstalk is usually distinguishable as speech or signaling tones.
Note 2: In video,… (Read More →)

The ratio of the power in a disturbing circuit to the induced power in the disturbed circuit observed at specified points of the circuits under specified terminal conditions.
Note: Crosstalk coupling is usually expressed in dB. Synonym crosstalk coupling loss.
