BCCS provides Electronic Key Systems (EKS) and Private Branch Exchanges (PBX). They are telephone systems in which the control functions are located in a cabinet at the agency's site and are generally used in areas where Centrex service is not available. These systems permit in-system intercom calling without using telephone company central office lines. They allow for system telephones to share the use of lines from the telephone company, thus reducing the need for individual telephone lines for each telephone.
EKS and PBX systems provide an electronic switching facility for telephones on extension lines within the building as well as access to the public telephone network. EKS systems can accommodate up to 64 telephone stations and require proprietary telephones. PBX systems can accommodate several thousand telephone stations. Optional features such as automated attendant, voice mail, Interactive Voice Recognition (IVR) systems and Automated Call Distributors (ACDs) may also be available for your EKS or PBX system.
Multiple vendors are under contract to provide equipment, service, maintenance, and repair.
BCCS telecommunications services are available to all state agencies, boards, commissions, universities, offices of the Illinois House and Senate, and Constitutional Officers.
