    • PURPOSE:To obtain a highly economical and flexible device by sending the signal tone by the indication given from the common control unit and through the intermittent operation of the realy of the trunk. CONSTITUTION:The signal tone is sent to the telephone set through operation of the relay by trunk driving unit TC and based on the command given from common control CC plus the signal tone output from signal tone generator SG and via the teritary winding of relay A. First dial tone DT is given by the comman given to TC from CC ordering to give relay S the intermittent operation with the cycle of 120 times per minute, and as a result signal tone output 400Hz is continued via the make contact and then transmitted to the telephone set. In case busy tone BT is transmitted from originating register ORT, the intermittent operation is given to relay S with the cycle of 60 times per minute through CC and the signal tone output of SG is transmitted to the telephone via the make contact s. And in case call signal RBT is transmitted to the caller, the intermittent operation command is given to relay T from CC in the cycle of 20 times per minute. And when holding tone HT is transmitted, the command is given to actuate relay S and T.

    • PURPOSE:To make the trunk having a transfer control function needless by performing an order service by the connection switching of service pathes in the channel and a normal mutual service trunk. CONSTITUTION:When telephone sets 1 and 2 are in service through trunk 12 and service path 13, a service path is switched from path 13 to path 14 by the transfer request of telephone set 1, and selection number information to transfer destination telephone set 3 is received from number receiving trunk 9, and telephone set 3 is called on a basis of this information to perform the connection switching to mutual service trunk 15, thereby performing the order service between telephone sets 1 and 3. Further, the service path is switched to path 18 by the transfer request from telephone set 1, thereby performing the service between telephone sets 2 and 3.
    • 目的:通过通道中的服务模板的连接切换和正常的相互业务中继线,使得具有传送控制功能的中继线不需要执行订单服务。 构成:当电话机1和2通过中继线12和业务路径13服务时,通过电话机1的传送请求将路径13从路径13切换到路径14,传送目的地电话机3的选择号码信息为 从号码接收中继线9接收到电话机3,并且根据该信息来呼叫电话机3,以进行到相互业务中继线15的连接切换,从而执行电话机1和3之间的订单业务。此外,业务路径切换到 路径18通过来自电话机1的传送请求,从而在电话机2和3之间执行服务。
