Member Function Documentation

virtual void attach

(

SS7Layer2 *

link

)

[virtual]

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

Parameters:

link

Pointer to data link to attach

Implements SS7L2User.

virtual bool control

(

NamedList &

params

)

[virtual]

Query or modify layer's settings or operational parameters

Parameters:

params

The list of parameters to query or change

Returns:

True if the control operation was executed

Reimplemented from SignallingComponent.

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

Execute a control operation on the linkset

Parameters:

	oper	Operation to execute
	params	Optional parameters for the operation

Returns:

True if the command completed successfully, for query operations also indicates the linkset is enabled and operational

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:

link

Pointer to data link to detach

Implements SS7L2User.

virtual bool initialize

(

const NamedList *

config

)

[virtual]

Configure and initialize the MTP3 and all its links

Parameters:

config

Optional 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:

link

Data 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:

sls

Signalling 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:

	msu	Message data, starting with Service Indicator Octet
	link	Data link that delivered the MSU
	sls	Signalling 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:

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

Returns:

Link the message was successfully queued to, negative for error

Implements SS7Layer3.
