Abstract

PURPOSE:To reduce a man-house for forming program of the exchange main body and to relieve traffic by performing the forced-releasing of a trunk through a timer circuit whose time-setting is optionally modified. CONSTITUTION:In an inteligent-type trunk 5, the timer circuit of which time- setting is optionally be modified from a CPU2 is provided. The time-up signal outputted by this timer is supplied as a restoration signal to the CPU2 by starting a normal trunk-restoring program in order to forced-release the trunk. Accordingly, because the program on the exchange main body side hardly performs all of the controlings, the man-hour for forming program on the said side is reduced, hence the traffic is relieved.

手段が設定される。First, when a call is made from the trunk 5 to the central control device 2, if a trunk disconnection service exists when the call time/minute warning sound is sent out, the central control device 2 will provide a timer means that can change the set time for the purpose of monitoring the call. Send the command to trunk 5. The trunk 5 is provided with a memory circuit (TIM) 6 (FIG. 2) for storing timer information, and the timer means is set for a predetermined set time by an instruction from the central control device 2.

Ｋ。As shown in FIG. 2, the memory circuit (TIM) 6 of the trunk 5 includes a timer type section (TCA) 6a that determines the timer setting time based on a command from the central control device 2, and a timer that displays the remaining amount of time during time measurement. It is composed of a chain part (TCB) sb. For example, if the timer type section 6a is "01", the cycle is 2 seconds, and if the timer type section 6a is "01", the cycle is 30 seconds. Further, the timer chain section 6b is incremented by Kl for each period indicated by the timer type section 6a. For example, the timer type section 6a is “
