Voice Telecommunications


Voice Telecommunications services are provided collaboratively by Connecticut State University System Office (CSUSO) and Western Information Technology & Innovation Personnel.


Voice communication and other dial tone services (fax, dial modem, etc.) are provided via a CSUSO owned and managed Avaya Definity PBX. The CSU telecommunications system consists of five telecommunications switches (PBXs), located at CCSU, ECSU, SCSU, WCSU and the CSU System Office. The switches are networked together to provide 5 digit dialing for campus to campus calls as well as cost effective in-state calling.  Some key features of the system include:

PBX nodes are located on both Western campuses.
The PBX is connected to the other CSU schools as well as our wide area service providers, by an advanced fiber optic wide area network (WAN).
The combination of local PBX and advanced WAN services provides a highly responsive and cost-effective telecommunications platform for the university.

System Management

Local provisioning and administration of voice services is managed by Information Technology & Innovation Personnel. Those services include:

How To - Request Service

All requests for telecommunications service (new service, changes to service or equipment, moves, disconnects, name changes, etc) are initiated via the Telecommunications Service Request Form (TSR).  TSRs must be reviewed and approved by your department head prior to submission. Please contact your department Secretary or designated representative for assistance in completing a TSR.
