IDCS Key Sets
A key system or key telephone system is a multi-line telephone system typically used in small office environments.

Key systems are noted for their expandability and having individual line selection buttons for each connected phone line, however some features of a private branch exchange such as dial-able intercoms may also commonly be present.

Key systems can be built using three principal architectures:

  • Electromechanical shared-control
  • Electronic shared-control
  • Independent keysets
