Abstract

PURPOSE:To ensure the automatic recalling service for the calling subscriber when no answer is given from the called subscriber, by installing the automatic transmitter. CONSTITUTION:Subscriber A's call of PB telephone is detected through sutomatic transmitter COE, and subscriber A is connected to PBOR by the relay action within LLF. With reception of the called subscriber number, MKR operates to select IOT or OGT. Thus, a channel is completed, and at the same time the start information is sent to COE. The COE releases the channel to IOT or OGT in case no answer signal is given from the called subscriber in a fixed time after the start. Thus, a connection is given to automatic transmission register sender CORS, and a special tone is sent to subscriber A. Then subscriber A transmits the called number again to have on-hooking. As a result, CORS gives calling with every fixed time, and COE completes the channel to subscriber A when the called subscriber gives an answer.
