Abstract
A shaper circuit is provided in a line adapter, not in an ATM switch. A billing section is provided on the output side of the shaper circuit. The shaper circuit is configured to output M cells for N cell slots at a temporally smooth rate, where M and N are integers. This configuration serves to optimize buffer capacity for shaping, prevents charging for discarded cells, and allows a full rate setting matched to a line speed.
