ABSTRACT:
In an auto dialling facsimile apparatus, data representive of telephone numbers of specified destinations are stored in a first memory and data representative of access time intervals are stored in a second memory corresponding respectively to the specified destinations. The stored data are retrieved from the first and second memory in response to the entry of a called station unique code supplied from a keyboard. Telephone switching signal is transmitted to a switched telecommunication network in accordance with data retrieved from the first memory to establish a connection through the network. The length of time elapsed from the time said dialling signal is transmitted is measured, the measured time length being reset when an answer signal is returned from the desired destination. The switched connection is released when the measured time length exceeds the access time interval represented by the data retrieved from the second memory.
