virtual void attach ( SS7Layer2 link) [virtual]

Attach a SS7 Layer 2 (data link) to the network transport. Attach itself to the link

Parameters:
linkPointer to data link to attach

Implements SS7L2User.

virtual bool control ( Operation  oper,
NamedList params = 0 
) [virtual]

Execute a control operation on the linkset

Parameters:
operOperation to execute
paramsOptional parameters for the operation
Returns:
True if the command completed successfully, for query operations also indicates the linkset is enabled and operational
virtual bool control ( NamedList params) [virtual]

Query or modify layer's settings or operational parameters

Parameters:
paramsThe list of parameters to query or change
Returns:
True if the control operation was executed

Reimplemented from SignallingComponent.

unsigned int countLinks ( ) [protected]

Count the total and active number of links

Returns:
Number of active links
virtual void destroyed ( ) [protected, virtual]

Detach all links and user. Destroys the object, disposes the memory

Reimplemented from SignallingComponent.

virtual void detach ( SS7Layer2 link) [virtual]

Detach a SS7 Layer 2 (data link) from the network transport. Remove the link's L2 user

Parameters:
linkPointer to data link to detach

Implements SS7L2User.

virtual bool initialize ( const NamedList config) [virtual]

Configure and initialize the MTP3 and all its links

Parameters:
configOptional configuration parameters override
Returns:
True if MTP3 and at least one link were initialized properly

Reimplemented from SignallingComponent.

unsigned int linksActive ( ) const [inline]

Get the number of links that are currently operational

Returns:
Number of operational data links
unsigned int linksTotal ( ) const [inline]

Get the total number of links attached

Returns:
Number of attached data links
virtual void notify ( SS7Layer2 link) [protected, virtual]

Process a notification generated by the attached data link

Parameters:
linkData link that generated the notification
Returns:
True if notification was processed

Implements SS7L2User.

virtual bool operational ( int  sls = -1) const [virtual]

Check if the network/linkset is fully operational

Parameters:
slsSignalling Link to check, negative to check if any is operational
Returns:
True if the linkset is enabled and operational

Implements SS7Layer3.

virtual bool receivedMSU ( const SS7MSU msu,
SS7Layer2 link,
int  sls 
) [protected, virtual]

Process a MSU received from the Layer 2 component

Parameters:
msuMessage data, starting with Service Indicator Octet
linkData link that delivered the MSU
slsSignalling Link the MSU was received from
Returns:
True if the MSU was processed

Implements SS7L2User.

virtual int transmitMSU ( const SS7MSU msu,
const SS7Label label,
int  sls = -1 
) [virtual]

Push a Message Signal Unit down the protocol stack

Parameters:
msuMessage data, starting with Service Indicator Octet
labelRouting label of the MSU used in routing
slsSignalling Link Selection, negative to choose best
Returns:
Link the message was successfully queued to, negative for error

Implements SS7Layer3.
