Rec. No. : X.5

Title :	Facsimile packet assembly/disassembly facility (FPAD) in a 
	public data network

Study Group : VII - Data Communications Networks

Version : New

Date of adoption : 1992

Notes :	


An FPAD is a facility which offers a G3 facsimile equipment the 
opportunity to use a public data network to convey facsimile control 
and image data to another G3 facsimile equipment or to an application 
DTE. The FPAD also allows an application DTE to establish a connection 
and to send control and image data to a G3 facsimile equipment.

It is an underlying principle of the FPAD environment that to the 
degree possible, the performance and quality of the service of the 
two G3 facsimile equipments as available today utilizing the general 
switched telephone network are not negatively affected.

Support for the following cases is provided in the FPAD Series of 
Recommendations:

	a) A G3 facsimile equipment to a G3 facsimile equipment - A 
	   G3 facsimile equipment establishes a call to a G3 facsimile 
	   equipment, dialling in one or two stages the number of the 
	   called G3 facsimile equipment:

	-  the calling G3 facsimile equipment transmits document(s) to 
	   the called G3 facsimile equipment;

	-  the called G3 facsimile equipment transmits document(s) to 
	   the calling G3 facsimile equipment.

	b) A G3 facsimile equipment to an application DTE - A G3 
	   facsimile equipment establishes a call to an application 
	   DTE, dialling in one or two stages the number of the called 
	   application DTE:

	-  the calling G3 facsimile equipment transmits document(s) 
	   to the called application DTE;

	-  the called application DTE transmits document(s) to the 
	   calling G3 facsimile equipment.

	c) An application DTE calling to a G3 facsimile equipment - An 
	   application DTE establishes a call to a G3 facsimile 
	   equipment:

	-  the calling application equipment transmits document(s) to 
	   the called G3 facsimile;

	-  the called G3 facsimile equipment transmits document(s) to 
	   the calling application DTE.
