Communication apparatus and control method thereof

摘要

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.

主权项

1. A communication apparatus having a plurality of lines, comprising:
a setting unit configured to set, for a line based on a user instruction, whether to permit transmission of data using the line; a selecting unit configured to select, automatically, a line from among lines which are set to permit transmission of data; a transmission unit configured to transmit data by the line selected by the selecting unit; and a changing unit configured to automatically change, for a line, a setting not to permit transmission of data using the line to a setting to permit transmission of data using the line, wherein when a predetermined line enters a disabled state and settings not to permit transmission of data are set for all lines other than the predetermined line, the changing unit automatically changes, for one line of the lines other than the predetermined line, the setting not to permit transmission of data using the one line to the setting to permit transmission of data using the one line.
