See spectral width.

The ratio of the signal power, at a given point in a transmission system, to a reference signal power.
Note: The ratio is usually determined by applying a standard test tone at zero transmission level point (or applying adjusted test tone power at any other point) and measuring the gain or loss to the location of interest. A distinction should… (Read More →)

1. To retransmit a received message from one station to another station.
2. An electromechanical or semiconductor switch (i.e., solid-state relay) in which a current or voltage applied across one port or terminal controls electrical currents or voltages that appear across another terminal or terminals.

An operating configuration in which a circuit is established between two stations via an intermediate relay station. Two links are used simultaneously and the channel connections at the relay station are accomplished completely within the station.

1. An intermediate station that passes information between terminals or other relay stations.
2. A fixed station used for the reception and retransmission of the signals of another station or stations. [47CFR]

The initial destination of a call from a pivot node.
Note: A service or network capability provided at the release node, after determining the call should be connected to a destination node other than itself, may invoke RTP (registration request protocol) to have the new connection established from a pivot node earlier in the call path. After releasing the call… (Read More →)

[A] prefix appended to the short title of U. S. -produced keying material to indicate its foreign releasability. "A" designates material that is releasable to specific allied nations and "U. S. " designates material intended exclusively for U. S. use. [INFOSEC-99]

1. The time interval between (a) the instant that an enabling signal (as in a vogad or echo suppressor) is discontinued, and (b) the instant at which suppression ceases.
2. The time interval between (a) the instant a relay coil is de-energized, and (b) the instant that contact closure ceases (or, depending on the nature of the relay, is established).

A timer that specifies the period of time the network will wait for a release from the user after informing the user of a failure condition such as busy. This timer is on the order of 30 seconds. [T1.620-1991]

Synonym switched loop.
