Detailed Description

SIGTRAN ISDN Q.921 User Adaptation Layer.

RFC4233 ISDN Layer 2 implementation over SCTP/IP IUA is intended to be used as a Provider-User where Q.921 runs on a Signalling Gateway and the user (Q.931) runs on an Application Server.

Constructor & Destructor Documentation

◆ ISDNIUA()

ISDNIUA	(	const NamedList &	params,
		const char *	name = `0`,
		u_int8_t	tei = `0`
	)

Constructor Initialize this object and the layer 2

Parameters

params	Object and Layer 2 parameters
name	Optional name for Layer 2
tei	Value of TEI for this component

◆ ~ISDNIUA()

virtual ~ISDNIUA ( )

virtual

Destructor

Member Function Documentation

◆ activeChange()

virtual void activeChange ( bool active )

virtual

Traffic activity state change notification

Parameters

active True if the ASP is active and traffic is allowed

Implements SIGAdaptUser.

◆ cleanup()

virtual void cleanup ( )

virtual

Emergency release.

Implements ISDNLayer2.

◆ iid()

int32_t iid ( ) const

inline

Retrieve the numeric Interface Identifier (if any)

Returns: IID value, -1 if not set

◆ initialize()

virtual bool initialize ( const NamedList * config )

virtual

Configure and initialize IUA and its transport

Parameters

config Optional configuration parameters override

Returns: True if IUA and the transport were initialized properly

Reimplemented from SignallingComponent.

◆ multipleFrame()

virtual bool multipleFrame	(	u_int8_t	tei,
		bool	establish,
		bool	force
	)

virtual

Implements Q.921 DL-ESTABLISH and DL-RELEASE request primitives

Parameters

tei	This layer's TEI
establish	True to establish. False to release
force	True to establish even if we already are in this mode. This parameter is ignored if establish is false

Returns: True if the request was accepted

Reimplemented from ISDNLayer2.

◆ sendData()

virtual bool sendData	(	const DataBlock &	data,
		u_int8_t	tei,
		bool	ack
	)

virtual

Implements Q.921 DL-DATA and DL-UNIT DATA request primitives

Parameters

data	Data to send
tei	The TEI to send with the data frane
ack	True to send an acknowledged frame, false to send an unacknowledged one

Returns: False if the request was not accepted or send operation failed

Reimplemented from ISDNLayer2.
