Generally, in a PABX system all of the extensions are not authorized to place a call on the public switch network without the assistance of the operator. When requesting the assistance of the operator, it may happen that the requested connection may not be established immediately, and some waiting call data recording means should be provided to the operator. This article describes a system in which the operator console unit is provided with a screen device, a cathode ray tube or the like, to display information on the waiting calls.
