ABSTRACT:
A cell assembling/disassembling system used for an ATM network system having a priority order cell discarding system which device can be operated with a reduced time delay associated with assembling/disassembling of a cell when a cell priority order control is applied. The cell assembling/disassembling system is provided with a first unit which sets a cell assembling device, when an amount of data currently being transmitted is more than a predetermined amount, to a first assembling mode where each of cells assembled by the cell assembling device has a discarding priority order. A second unit sets a cell disassembling device, when the cell assembling device performs a cell assembling operation using the first assembling mode, to a first disassembling mode where cells having the discarding priority order are disassembled. A third unit sets the cell assembling device, when the amount of data currently being transmitted through the ATM network is less than the predetermined amount, to a second assembling mode where a regular cell assembling operation by which no discarding priority order is provided to cells is performed. A fourth unit sets the cell disassembling device, when the cell assembling device performs a cell assembling operation using the second assembling mode, to a second disassembling mode where cells having no discarding priority order are disassembled.
