<p>PURPOSE: To shorten the conversion processing time and gathering processing time, and to reduce the circuit scale with respective to the cell relay service control system for physical address conversion and statistical data gathering at a node device of cell relay service. CONSTITUTION: The cell relay service controller of a cell relay switching system is provided with a VCC table 11 consisting of tables of plural planes where physical address numbers of VC service connections are registered by VPI values by using VCI values as offset addresses, a 1st selector 12 which selects the table of a specific plane of the VCC table 11 according to a VPI value, and a 2nd selector 12 which refers to the selected table according to a VCI value. Both selectors are controlled to convert the VPI value plus BCI value of a VC service connection into a physical address number.</p> |
