Detailed Description

Abstract ISDN layer 3 (Q.931) message transport.

An interface to a Layer 3 (Q.931) ISDN message transport

Constructor & Destructor Documentation

◆ ISDNLayer3()

ISDNLayer3 ( const char * name = 0 )

inlineprotected

Constructor Initialize the component

Parameters

name	Name of this component

References SignallingComponent::SignallingComponent().

Member Function Documentation

◆ attach()

virtual ISDNLayer2 * attach ( ISDNLayer2 * layer2 )

inlinevirtual

Attach an ISDN Q.921 Layer 2

Parameters

layer2 Pointer to the Q.921 Layer 2 to attach

Returns: Pointer to the detached Layer 2 or NULL

Reimplemented in ISDNQ931.

◆ dataLinkState()

virtual void dataLinkState	(	u_int8_t	tei,
		bool	cmd,
		bool	value,
		ISDNLayer2 *	layer2 )

inlinevirtual

Notification from layer 2 of data link set/release command or response Used for stateless layer 2

Parameters

tei	The TEI of the command or response
cmd	True if received a command, false if received a response
value	The value of the notification If 'cmd' is true (command), the value is true if a request to establish data link was received or false if received a request to release data link If 'cmd' is false (response), the value is the response
layer2	Pointer to the notifier

Reimplemented in ISDNQ921Management, and ISDNQ931Monitor.

◆ idleTimeout()

virtual void idleTimeout ( ISDNLayer2 * layer2 )

inlinevirtual

Notification from layer 2 of data link idle timeout Used for stateless layer 2

Parameters

layer2 Pointer to the notifier

Reimplemented in ISDNQ931Monitor.

◆ l3Mutex()

Mutex & l3Mutex ( )

inlineprotected

Retrieve the layer's mutex

Returns: Reference to the Layer 3 mutex

◆ multipleFrameEstablished()

virtual void multipleFrameEstablished	(	u_int8_t	tei,
		bool	confirm,
		bool	timeout,
		ISDNLayer2 *	layer2 )

inlinevirtual

Implements Q.921 DL-ESTABLISH indication/confirmation primitive: 'multiple frame acknowledged' mode established

Parameters

tei	The TEI of the frame
confirm	True if this is a confirmation of a previous request. False if it is an indication of state change on remote request
timeout	True if the reason is a timeout
layer2	Pointer to the notifier

Reimplemented in ISDNQ921Management, and ISDNQ931.

◆ multipleFrameReleased()

virtual void multipleFrameReleased	(	u_int8_t	tei,
		bool	confirm,
		bool	timeout,
		ISDNLayer2 *	layer2 )

inlinevirtual

Implements Q.921 DL-RELEASE indication/confirmation primitive: 'multiple frame acknowledged' mode released

Parameters

tei	The TEI of the frame
confirm	True if this is a confirmation of a previous request. False if it is an indication of state change on remote request
timeout	True if the reason is a timeout.
layer2	Pointer to the notifier

Reimplemented in ISDNQ921Management, and ISDNQ931.

◆ receiveData()

virtual void receiveData	(	const DataBlock &	data,
		u_int8_t	tei,
		ISDNLayer2 *	layer2 )

pure virtual

Implements Q.921 DL-DATA and DL-UNIT DATA indication primitives Receive data from remote peer

Parameters

data	Received data
tei	The TEI of the received frame
layer2	Pointer to the sender

Implemented in ISDNQ921Management, ISDNQ931, and ISDNQ931Monitor.
