Intelligent Switching - A feature of multiplexers that enables every call to be routed through the shortest distance, and one that takes into account traffic at any given time to avoid congestion or network failures.

Intelligent Terminal - A data terminal that contains a processing element. It can perform local data processing and storage activities.

INTELSAT - International Telecommunications Satellite (Organization)

Interconnect Company - A vendor of telecommunications Customer Premise Equipment (CPE) other than a Bell Operating Company (RBOC) or AT&T. This term was originated by AT&T and was meant to be derisive towards the fledgling industry when the courts said it was OK for end users to buy equipment from someone other than the Bell System. This industry flourished, in spite of AT&T°Ã~s disdain, and ironically the RBOCs were not allowed to sell CPE under the terms of the break up of AT&T. With the current state of deregulation, the RBOCs are slowly re-entering this business.

Interdomain Call - A call that originates in one domain, possibly passes through a transit domain, and terminates in another domain.

Interdomain Call ID - See virtual call ID.

Interexchange Carrier - See IEC.

Interface - A point between two devices where electrical signals, connectors, timing, and handshaking meet.

Interface Signal - A method of physical signaling defined by various specifications such as V.24, V.35, V.36, RS-232, and RS-449.

Intermediate Rate - A subrate data rate formed by combining two or more adjacent 9.6 DS0B subrate channels to form a 19.-, 28.8-, or 38.4 kbps circuit.

Internal Timing - When the node is the clock source.

InterNIC - Internet Network Information Center

Interrupt - A means of gaining access in a CPU or network to get a desired service.

Intradomain Call - A call that originates and terminates within the same domain.

Inverse Multiplexing - A method of combining and later separating 2 data streams that does not involve the telephone network. Inverse multiplexing is the most common way of achieving this function in Codecs operating at 128kbps or less over ISDN.

IP (Internet Protocol) - The network layer for the TCP/IP protocol suite used in Ethernet networks. It provides packet routing, fragmentation, and re-assembly through the date link layer.

IP Access List - Also known as the IP Routing Table. The IP Route Server Node is the designated node that maintains the database for the IP routing table, and also advertises or floods the IP routes throughout the domain. Any Promina 800 series node can be the IP Route Server Node. There can be multiple IP Route Server Nodes within a domain providing they are configured as server nodes serving different routes. Each IP Route Server node can have 16 entries in the IP access list.

IP Gateway Node - The IP Gateway Node is the designated Promina node that is connected to the external Network Management System (NMS) or PanaVue. This node broadcasts the IP access tables to all the network nodes and routers within the domain.

IP Routing - IP packets are routed over the Promina network to enable applications running on the attached workstations to communicate with the Promina processor cards using the Internet Protocol. Designed for internal N.E.T. IP traffic only.
