This document outlines UEN’s guidelines for implementing a VoIP communication link through its network. The implementation process is defined separately by UEN Technical Services and will be modified as needed. UEN was established to provide Utah students and educators with electronic access to educational services that improve student achievement through high-quality, cost-effective networking through existing public telecommunication services.
Voice Over Internet Protocol (VoIP): a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet rather than the public switched telephone system (PSTN).
VoIP Network: a Public Telecommunication Network over which VoIP Services are provided.
VoIP Service(s): all of the services and technologies that allow the transmitting, receiving, delivering and routing of voice telecommunications by means of internet protocol (IP); i.e., commercial VoIP, PBX VoIP, hosted PBX or any like service regardless of branded terminologies.
Public Switched Telephone Network (PSTM): also referred to as the Plain Old Telephone Service (POTS), is the network of the world’s public circuit-switched telephone networks.
Internet Service Provider (ISP): a company that offers its customers access to the Internet. The ISP connects to its customers using a data transmission technology appropriate for delivering IP such as dial-up, DSL, cable modem, wireless or dedicated high-speed interconnects.
Firewall: a technological barrier designed to prevent unauthorized or unwanted communications between computer networks or hosts.
Enhanced 911, E-911 or E911: a North American telecommunications-based system that automatically associates a physical address with the calling party’s telephone number and routes the call to the most appropriate Public Safety Answering Point (PSAP) for that address. The caller’s address and information is displayed to the call taker immediately upon call arrival. This provides emergency responders with the location of the emergency without the person calling for help having to provide it.
Assisted Global Positioning System (GPS): a system which can improve the startup performance of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones, making the location of a cell phone available to emergency call dispatchers.
Border Gateway Protocol (BGP): the protocol that backs the core routing decisions on the Internet. It maintains a table of IP networks, or prefixes, which designate network reachability among autonomous systems (AS). It is described as a path vector protocol. BGP does not use traditional Interior Gateway Protocol (IGP) metrics, but makes routing decisions based on path, network policies and/or rule sets. For this reason, it is more appropriately termed a reachability protocol rather than routing protocol.
Abstract Syntax Notification (ASN): a standard and flexible notation that describes data structures for representing, encoding, transmitting and decoding data. It provides a set of formal rules for describing the structure of objects that are independent of machine-specific encoding techniques and is a precise, formal notation that removes ambiguities.
Synchronous Optical Networking (SONET) Protocols: standardized multiplexing protocols that transfer multiple digital bit streams over optical fiber using lasers or lightemitting diodes (LEDs).
Time-Division Multiplexing (TDM): a type of digital or (rarely) analog multiplexing in which two or more signals or bit streams are transferred apparently simultaneously as sub-channels in one communication channels, but are physically taking turns on the channel.
