virtual ISDNLayer2* attach

(

ISDNLayer2 *

layer2

)

[inline, virtual]

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.

virtual void dataLinkState	(	u_int8_t	tei,
		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:

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 ISDNQ931Monitor, and ISDNQ921Management.

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.

Mutex& l3Mutex

(

)

[inline, protected]

Retrieve the layer's mutex

Returns:

Reference to the Layer 3 mutex

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

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 ISDNQ931, and ISDNQ921Management.

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

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 ISDNQ931, and ISDNQ921Management.

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 ISDNQ931Monitor, ISDNQ931, and ISDNQ921Management.
