Class PCCircuitManager

java.lang.Object
  hp.opencall.media.signalling.PCCircuitManager

public class PCCircuitManager

extends java.lang.Object

PCCircuitManager is the Point Code Circuit Manager.

This circuit manager update the circuit states thanks to the connection provider that calls the setState method.
Its embedded data base allows to supply an available circuit when the connection provider need to establish an outgoing call.
The circuit allocation algorithm is provisioned with the OCMP configuration tools.

Method Detail

setState

public static void setState(long dpc,
                            int cic,
                            hp.opencall.media.tdm.CircuitState aCircuitState)
                     throws hp.opencall.media.common.ResourceNotAvailableException

Set the state of circuit.

Parameters:

cic - specifies the Circuit Identifier Code

aCircuitState - specifies the new circuit state

Throws:

hp.opencall.media.common.ResourceNotAvailableException - if the circuit is unknown

getOutgoingCircuit

public static long getOutgoingCircuit(long dpc)
                               throws hp.opencall.media.common.ResourceNotAvailableException

get a free circuit to establish an outgoing call.

Parameters:

dpc - is the Destination Point Code to reach

Throws:

hp.opencall.media.common.ResourceNotAvailableException - if no circuit match for the request

getOutgoingCircuit

public static long getOutgoingCircuit(long dpc,
                                      int cic)
                               throws hp.opencall.media.common.ResourceNotAvailableException

get a specific free circuit to establish an outgoing call.

Parameters:

dpc - is the Destination Point Code to reach

cic - is the Circuit Identifier Code required

Throws:

hp.opencall.media.common.ResourceNotAvailableException - if the circuit does not match for the request
