Member Function Documentation

virtual void attach

(

ISDNLayer2 *

layer2

)

[inline, virtual]

Attach an ISDN Q.921 Layer 2

Parameters:

layer2

Pointer to the Q.921 Layer 2 to attach

Reimplemented in ISDNQ931.

virtual void dataLinkState	(	bool	cmd,
		bool	value,
		ISDNLayer2 *	layer2
	)			[inline, virtual]

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

Parameters:

	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 ISDNQ931Monitor.

virtual void idleTimeout

(

ISDNLayer2 *

layer2

)

[inline, virtual]

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

Parameters:

layer2

Pointer to the notifier

Reimplemented in ISDNQ931Monitor.

virtual void multipleFrameEstablished	(	bool	confirm,
		bool	timeout,
		ISDNLayer2 *	layer2
	)			[inline, virtual]

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

Parameters:

	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 ISDNQ931.

virtual void multipleFrameReleased	(	bool	confirm,
		bool	timeout,
		ISDNLayer2 *	layer2
	)			[inline, virtual]

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

Parameters:

	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 ISDNQ931.

virtual void receiveData	(	const DataBlock &	data,
		bool	ack,
		ISDNLayer2 *	layer2
	)			[pure virtual]

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

Parameters:

	data	Received data
	ack	True if data is an acknoledged frame, false if it is an unacknoledged one
	layer2	Pointer to the sender

Implemented in ISDNQ931, and ISDNQ931Monitor.
