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 SS7SCCP, and SS7ISUP.

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 SS7SCCP, and SS7ISUP.

static unsigned char getSIO	(	const NamedList &	params,
		unsigned char	sif,
		unsigned char	prio,
		unsigned char	ni
	)		[static]

Get a SIO value from a parameters list

Parameters:

params	Parameter list to retrieve "service", "priority" and "netindicator"
sif	Default Service Information Field to apply parameters to
prio	Default Priority Field to apply parameters to
ni	Default Network Indicator Field to apply parameters to

Returns:

Adjusted SIO value

static unsigned char getSIO	(	const NamedList &	params,
		unsigned char	sif,
		unsigned char	ssf
	)		[inline, static]

Get a SIO value from a parameters list

Parameters:

params	Parameter list to retrieve "service", "priority" and "netindicator"
sif	Default Service Information Field to apply parameters to
ssf	Default Subservice Field to apply parameters to

Returns:

Adjusted SIO value

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.

Reimplemented in SS7SCCP, SS7ISUP, and SS7Testing.

SS7Layer3* network

(

)

const [inline]

Retrieve the SS7 network or router to which this service is attached

Returns:

Pointer to the network or router this service is attached to

unsigned char ni

(

)

const [inline]

Get the default sending Network Indicator bits for this protocol

Returns:

Network Indicator bits

unsigned char prio

(

)

const [inline]

Get the default sending Priority bits for this protocol

Returns:

Priority bits

unsigned char sif

(

)

const [inline]

Get the Service Information Field (SS7 protocol number)

Returns:

SIF value used in matching and sending MSUs

unsigned char sio

(

)

const [inline]

Get the default sending Service Information Octet for this protocol

Returns:

SIO value

unsigned char ssf

(

)

const [inline]

Get the default sending Service Switching Function bits for this protocol

Returns:

Combined Priority and Network Indicator bits

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

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
