ABSTRACT:
A facsimile machine includes an automatic calling and answering net control unit (AA-NCU) which is connected to a private automatic branch exchange (PABX). The AA-NCU has three modes of operation in accessing an outside line, typically a public telephone line. The access mode of operation is set and stored when the facsimile machine is first connected to a particular PABX having a particular outside line access mode. A call control procedure is also set and stored in the facsimile machine. When the information input by an operator agrees with the stored call control procedure, the AA-NCU is controlled to place a call to an outside line in a mode appropriate for the associated PABX automatically.
