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.

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.
