Local Telephone (PBX) Services

The Division of State Information Technology (DSIT) uses several effective methods to provide our agencies with an efficient and cost-effective telephone service based on their location.

Understand the Service

• DSIT Private Branch Exchange (PBX)
  DSIT currently owns and maintains a network of PBX switches that connect multiple locations in Columbia, Charleston, Orangeburg, Greenville and Florence. These switches provide enhanced features such as:
    
  • Call Centers
  • Conference Calls
  • EC500
  • Reserved/Suspended Numbers
  • Voice Mail

• DSIT Centrex
  Contracts exist with service providers to offer Centrex services for multiple locations that are managed by DSIT.
       
• Non-DSIT Centrex
  Contracts exist with several providers for basic single line telephone service with essentially the same features to the desktop that are available with a PBX or key system. This Centrex service is provided by software in a telephone company’s local central office.     
       
• Non-Centrex Local Service
  Contracts exist for local telephone services that are provided by all local exchange companies (LEC) in South Carolina as well as several competitive local exchange companies (CLEC).
