Abstract
This invention provides a communication apparatus, which designates, when a line designated as that used for a specific application falls into a disabled state, another line as a new line used for the specific application. To accomplish this, even when at least one of a plurality of lines falls into a disabled state, and when the line in the disabled state is designated as a line used for the specific application, the communication apparatus designates a line other than the line in the disabled state among the plurality of lines as a new line used for the specific application.
Claims11
A communication apparatus having a plurality of lines, comprising:
- a detection unit configured to detect if at least one line of the plurality of lines has fallen into a disabled state;
- a determination unit configured to determine, when the detection unit detects that the at least one line of the plurality of lines has fallen into the disabled state, whether or not the line that has fallen into the disabled state is designated as a line used for a specific application;
- and
- a designation unit configured to designate, when it is determined as a result of determination by the determination unit that the line that has fallen into the disabled state is designated as the line used for the specific application, a line other than the line that has fallen into the disabled state of the plurality of lines as a new line used for the specific application.
A method of controlling a communication apparatus having a plurality of lines, comprising:
- detecting if at least one line of the plurality of lines has fallen into a disabled state;
- determining, when it is detected in the detecting step that the at least one line of the plurality of lines has fallen into the disabled state, whether or not the line that has fallen into the disabled state is designated as a line used for a specific application;
- and
- designating, when it is determined as a result of determination in the determining step that the line that has fallen into the disabled state is designated as the line used for the specific application, a line other than the line that has fallen into the disabled state of the plurality of lines as a new line used for the specific application.
A computer-readable storage medium containing computer-executable instructions that controls a communication apparatus having a plurality of lines, the medium comprising:
- computer-executable instructions that detect if at least one line of the plurality of lines has fallen into a disabled state;
- computer-executable instructions that determine, when it is detected in the detecting step that the at least one line of the plurality of lines has fallen into the disabled state, whether or not the line that has fallen into the disabled state is designated as a line used for a specific application;
- and
- computer-executable instructions that designate, when it is determined that the line that has fallen into the disabled state is designated as the line used for the specific application, a line other than the line that has fallen into the disabled state of the plurality of lines as a new line used for the specific application.
