    摘要: A conference system, in which a buffer memory is connected to the input-output of each highway for storing all its channel data for each frame. The stored data is time-divided so that a time-length obtained by dividing one frame length by an appropriate number (for example, eight) may be the operation time length of each trunk, thereby implementing real-time processing a number of trunks. Conference circuits capable of inhibiting an output for each channel are connected in parallel to the highways. During an ordinary two-party communication operation an output on the corresponding channel of the conference circuit is inhibited, and during a conference operation an output on the corresponding channel of the highway switching circuit is inhibited, by which channels allocated to telephone sets or CO lines are used for the conference without the necessity of providing channels specifically therefor.

    摘要: A synchronization system for a key telephone system, in which key information or the like information signal between a key service unit and each key telephone set is transmitted in the form of a time-division pulse signal under the control of a counter provided in the key service unit. The information signal has a format which is divided into a first signal from the key service unit to each key telephone set and a second signal from each key telephone set to the key service unit so as to make distinction between the first and second signals in terms of time. The first signal is disposed in a time slot preceding the second signal to provide a pair of signal groups. A one-pulse start signal is disposed in the foremost time slot of the signal groups and a one-pulse answer signal is disposed in a time slot between the first signal and the second signal.

    摘要: A rotary dial device for a telephone set, in which an additional function of preventing a toll dialling is provided. In accordance with this invention, a contact is further attached to an usual dial to classify dial impulses so that when a number "1," one of numbers "2" to "9," and a number "0" are dialled, one, two and three pulses are produced respectively. The dialling function subsequent to the first dialling number "0" and the first and second dialling numbers "10" is effectively stopped by counting the classified pulses.
