PURPOSE:To realize an automatic answering telephone system of the central office concentrated installation type which is capable of hearing the message even at the place outside the residence or office, by giving the proper secret number to every subscriber. CONSTITUTION:In case subscriber 1 wants to know the telephone message received during this absence within the residence of subscriber 7 or at a public telephone, the specified number is dialed through 7. Thus secret number reception unit 10 urges 7 to dial the secret number of 1 through trunk line unit 8 for the automatic answering telephone and link 9, and then receives and stores the number dialed. When the coincidence is obtained between the dialed secret number and the secret number of 1 which is stored previously in secret number memory device 11, comparison/collation circuit 12 gives the control to unit 8 via unit 10 and link 9 to secure the hearing of the recorded section which is allotted to 1 in automatic answering telephone recording unit 5 for the connection from 7. |
