发明名称 Facsimile apparatus capable of preventing receipt of unauthorized facsimile transmissions
摘要 A facsimile apparatus capable of performing the closed communication with specific calling offices by the setting in a called office. The called office previously registers identification data of predetermined calling offices. When a call is received from a calling office, the called office detects the identification data of the calling office from a control signal for standardized transmission control procedures received from the calling office, and compares the detected identification data with the registered identification data. When coincidence between the both identification data is detected, the communication is enabled between these offices.
