A mutually synchronized network in which all clocks in the network are of equal status and exert equal amounts of control on the others, the network operating clock pulse repetition rate being the mean of the natural (uncontrolled) clock pulse repetition rates of the population of clocks.

A synchronized network in which a unique master clock controls all other clocks in the network. [From Weik '89]

A network, or circuit, that produces an output waveform that is the time derivative of the input waveform.
Note: Differentiating networks are used in signal processing, such as for producing short timing pulses from square waves.

See integrated digital network.

A network structure in which the network resources, such as switching equipment and processors, are distributed throughout the geographical area being served.
Note: Network control may be centralized or distributed.

A distributed multi-access network that (a) supports integrated communications using a dual bus and distributed queuing, (b) provides access to local or metropolitan area networks, and (c) supports connectionless data transfer, connection-oriented data transfer, and isochronous communications, such as voice communications.

A managed IP network that is used for emergency services communications, and that can be shared by all public safety agencies. It provides the IP transport infrastructure upon which independent application platforms and core functional processes can be deployed, including, but not restricted to, those necessary for providing NG911 services. ESInets may be constructed from a mix of dedicated and… (Read More →)

1. In a system, a network that may replace another network without altering the performance of the system.
2. A network with external characteristics that are identical to those of another network.
3. A theoretical representation of an actual network.

The body responsible for coordinating networking needs among U. S. Federal agencies.
