integrated optical circuit (IOC)

A circuit, or group of interconnected circuits, consisting of miniature solid-state optical components on semiconductor or dielectric substrates.
Note: IOC components include light sources, optical filters, photodetectors, and thin-film optical waveguides.

Integrated Services Digital Network (ISDN)

An integrated digital network in which the same time-division switches and digital transmission paths are used to establish connections for different services.
Note 1: ISDN services include telephone, data, electronic mail, and facsimile.
Note 2: The method used to accomplish a connection is often specified: for example, switched connection, nonswitched connection, exchange connection, ISDN connection.

integrated station

A terminal device in which a telephone and one or more other devices, such as a video display unit, keyboard, or printer, are integrated and used over a single circuit.

integrated system

A telecommunication system that transfers analog and digital traffic over the same switched network.

integrating network

A network (circuit) that produces an output waveform that is the time integral of the input waveform.
Note: Integrating networks are used in signal processing, such as for producing sawtooth waves from square waves.

integrity

1. [In INFOSEC, the] quality of an information system (IS) reflecting the logical correctness and reliability of the operating system; the logical completeness of the hardware and software implementing the protection mechanisms; and the consistency of the data structures and occurrence of the stored data. Note that, in a formal security mode, integrity is interpreted more narrowly to mean protection… (Read More →)

integrity check value

[A] checksum capable of detecting modification of an information system (IS). [INFOSEC-99]

intelligent network (IN)

1. A network that allows functionality to be distributed flexibly at a variety of nodes on and off the network and allows the architecture to be modified to control the services.
2. In North America, an advanced network concept that is envisioned to offer such things as (a) distributed call-processing capabilities across multiple network modules, (b) real-time authorization code verification,… (Read More →)
