Abstract: A telecommunication and development system for the switching of voice and data under computer control in a customer programmable environment that allows real-time modification of communication services. The computer program controlling the system is written in a nonprocedural language that allows for the direct control of the telecommunication system on the basis of state definition, event definition, and action definition. Program scripts define a particular feature, and each script consists of a plurality of triples that automatically respond to the system state and signal information to execute the necessary actions to provide part of a feature to the telecommunication system. During provision of telecommunication services, a customer can add new features that not only add new operations to the system, but modify existing operations without interfering with the present operation of the system.

Abstract: A facsimile device with an automatic dialing signal transmission system, which includes a first memory circuit storing the phone numbers of the primary receiving station, and a second memory circuit storing the phone numbers of the secondary receiving stations which act as substitutes for the primary stations. A device is provided for detecting non-connection to the primary station that transmitted dialing signals in accordance with the phone numbers stored in the first memory circuit, and a device is also provided for automatically transmitting dialing signals by reading the phone numbers stored in the second memory circuit in response to the non-connection detector device mentioned above.
