Abstract:
A cell bandwidth control apparatus that is connected to an output highway of an ATM switch converts a transmission speed of data on the output highway to the speed of the input line side, and transmits the converted data to a line, comprising:forced empty cell inserting means for inserting a forced empty cell into the output highway to fill out the excess portion of a bandwidth of the outgoing highway over an effective bandwidth within the ATM exchange; andOAM cell inserting means for inserting an OAM cell into the other portion of the bandwidth unused by the forced empty cellsaid forced empty cell inserting means inserts a forced empty cell in an outgoing highway leading from said ATM switch to said line adapter, thereby limiting the line bandwidth of said outgoing highway to within the bandwidth of said line accommodated in said line adapter.
