Abstract
A telephone status recognition and bypass system includes a plurality of status recognition units, and a controller. Each status recognition unit interfaces a subscriber's telecommunication line between a plurality of peripheral services and to a switch network, and includes status monitoring circuits and an SRU switch. The status monitoring circuits monitor status of calls incoming to and outgoing from the service subscriber, and produces status signals representative thereof. The SRU switch switchably interconnects the service subscriber, the switch network, and the peripheral services, for telecommunications in response to switching control signals. The controller is responsive to the status monitoring circuits, and produces switching control signals as a function of the status signals. The controller causes the SRU switch to interconnect the service subscriber to the selected peripheral service, thereby passing the switch network, when the status monitoring means produces status signals representative of an outgoing call from the service subscriber to the peripheral service.
