Communication apparatus which can connect a plurality of communication lines

A communication apparatus having a plurality of ports to connect a plurality of communication lines, comprising:

• memory means for storing first information which includes information representing whether the communication line connected to each of the plurality of ports is at least an external line or an extension, and second information which represents a kind of the communication line to be connected to each of the plurality of ports, the second information including information representing whether the connected line is a first communication line or a second communication line;
• designating means for designating whether an outgoing call to be subsequently executed is executed to the external line or the extension;
• and
• selecting means for selecting, according to the designation by said designating means and the first and second information stored in said memory means, to which communication line of the port the outgoing call is to be executed.

A communicating apparatus having a plurality of ports to connect a plurality of communication lines, comprising:

• memory means for storing first information which includes information representing whether the communication line connected to each of the plurality of ports is at least an external line or an extension, and second information which represents a kind of the communication line to be connected to each of the plurality of ports, the second information including information representing whether the connected line is an analog communication line or a digital communication line;
• display means for displaying a classification of the lines being connected to the parts in accordance with the first information stored in said memory means;
• designating means for designating whether an outgoing call to be subsequently executed is executed to the external line or the extension;
• and
• selecting means for selecting, according to the designation by said designating means and the first and second information stored in said memory means, to which communication line of the port the outgoing call is to be executed.

A line selection method in a communication apparatus which has a plurality of ports to connect a plurality of communication lines, said method comprising the steps of:

• previously registering first information which includes information representing whether the communication line connected to each of the plurality of ports is at least an external line or an extension, and second information which represents a kind of the communication line to be connected to each of the plurality of ports, the second information including information representing whether the connected line is a first communication line or a second communication line;
• designating whether an outgoing call to be subsequently executed is executed to the external line or the extension;
• and
• selecting, according to the designation in said designating step and the first and second information, to which communication line of the port the outgoing call is to be executed.
