1. In a semiconductor, the range of electron energy, higher than that of the valence band, sufficient to make the electrons free to move from atom to atom under the influence of an applied electric field and thus constitute an electric current.
2. In the atomic structure of a material, a partially filled or empty energy level in which electrons… (Read More →)

Energy transfer achieved by means of physical contact, i.e., coupling other than inductive or capacitive coupling.
Note 1: Conductive coupling may be achieved by wire, resistor, or common terminal, such as a binding post or metallic bonding.
Note 2: Conductive coupling passes the full spectrum of frequencies, including dc. Synonym direct coupling.

Synonym antenna blind cone.

Acronym for connectivity exchange.

In conference calling, the state in which conference resources have been allocated to the specified conference and at least one party has a connection to the conference. That connection could be either active or held. [T1.647-1995]

A service feature that allows a call to be established among three or more stations in such a manner that each of the stations is able to communicate with all the other stations. Synonym multiple call.

In audio and video teleconferences, the user in charge of the conference when the service is invoked and the conference reaches the active state.
Note: The conference controller may perform any or all of the following actions: drop, floating, isolate, reattach, and split. [After T1.647-1995] Synonym [loosely] moderator.

In conference calling, the state in which the conference is active but without a controller. This state is possible when two or more conferees exist on an active conference and the controller successfully disconnects himself/herself. [T1.647-1995]

In conference calling, the served user's (or controller's) reference to the conference itself. [T1.647-1995]

In conference calling, the state prior to the receipt of a "conference invocation request," or after a particular conference has ended. [T1.647-1995]
