Member Function Documentation

◆ attach()

virtual void attach ( SS7Layer3 * network )

virtual

Attach a SS7 network or router to this service. Detach itself from the old one if valid

Parameters

network Pointer to network or router to attach

Implements SS7L3User.

Reimplemented in SS7ISUP, and SS7SCCP.

References network().

◆ destroyed()

virtual void destroyed ( )

virtual

This method is called to clean up and destroy the object after the reference counter becomes zero

Reimplemented from SignallingComponent.

Reimplemented in SS7ISUP, and SS7SCCP.

◆ getSIO() [1/4]

unsigned char getSIO ( const NamedList & params ) const

inline

Get a SIO value from a parameters list

Parameters

params Parameter list to retrieve "service", "priority" and "netindicator"

Returns: Adjusted SIO value

◆ initialize()

virtual bool initialize ( const NamedList * config )

virtual

Initialize the application layer, connect it to the SS7 router

Parameters

config Optional configuration parameters override

Returns: True if the application was initialized properly

Reimplemented from SignallingComponent.

		int	sls = -1 )

inlineprotected

Ask the Layer 3 to push a Message Signal Unit down the protocol stack

Parameters

msu	Message data, starting with Service Indicator Octet
label	Routing label of the MSU to use in routing
sls	Signalling Link Selection, negative to choose best

Returns: Link the message was successfully queued to, negative for error
