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.

Member Function Documentation

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.

virtual void cleanup

(

)

[virtual]

Emergency release.

Implements ISDNLayer2.

int32_t iid

(

)

const [inline]

Retrieve the numeric Interface Identifier (if any)

Returns:

IID value, -1 if not set

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.

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.

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.
