Abstract:
A connection control method for use in a switch where a fixed-length cell input from a first or second line via a first or second line response unit is transferred to the second or first line as opposed to the first or second line via the second or first line response unit as opposed to the first or second line response unit, by being self-switched in the switch, according to routing information which is set in a header and added to the fix length cell, comprising the steps of:transmitting a connection control cell where connection identification information corresponding to a specified connection is set, routing information indicating a route to the second or first line response unit as opposed to the first or second line response unit is set in the header, connection control information identifying it as the connection control cell is set in an empty area of the header, and connection information for controlling the specified connection is stored, to the switch by the first or second line response unit;extracting the connection control cell reciprocally by the first and second line response units input from the switch according to the connection control information; andstarting inflow of subscriber cells corresponding to the specified connection from the first line or the second line according to the connection information in the extracted connection control cell by the first line response unit or second line response unit.
