Abstract
A line card (1) in a private branch exchange (1) accommodates interfaces (1) which switch standard output frames on a system bus. These standard output frames contain control data in addition to subscriber data. As a result, the system frame of the system bus (SB) is not filled efficiently. By switching only the subscriber data from the standard output frames to the system bus by the switching means, the system frame is filled efficiently.
