Description
Centrex is a central office-based telecommunications system owned by an outside service provider. It typically provides an agency direct dial numbers per user and does not require on-site common control equipment such as an Electronic Key System (EKS) or Public Branch Exchange (PBX). Centrex allows for easy unification of multiple sites in a centralized area by providing a common abbreviated dialing plan that can be used to dial between any two telephones that are in Centrex. Centrex provides a basic feature set and is usually delivered via analog access lines with digital lines available for larger sites. It also includes access to local and long distance calling as well as voice messaging.
Centrex system allows incoming calls to be dialed direct without the assistance of an operator. Centrex equipment is located at the local telephone company's central office premises and every telephone served by the Centrex system is directly connected to the telephone company switching center. A Centrex system offers many different features for telephone users.
The telecommunications services of the Department of Innovation and Technology (DoIT) are available to all State of Illinois agencies, boards, commissions, universities, Offices of the Illinois House and Senate, and Constitutional Officers.
