Subject: Comments to Jeffs AP proposal

Jeff asked me to formulate a proposal for the required changes in
appendix D.

The following comments refer to the CPI-C 2.0 revised 3rd draft (Dec 15).

It was my proposal to identify the absence of a map name with the
UDT U-ASE. If this proposal is accepted we can change appendix D
in the following manner:

Page 404 (table 34):

	Change
		(TP-DATA request) UD-TRANSFER request
	to
		TP-DATA request

Pages 411 to 415 (table 46):

	Change
		(TP-DATA request) UD-TRANSFER request
	to
		TP-DATA request

	Change
		(See note at end of table.)
	to
		(See notes at end of table.)

Page 415: Suffix the following text at the end of table 46:

		TP-DATA request is only a template.
		If the map_name characteristic is Null, then TP-DATA request
		has to be interpreted as UD-TRANSFER request.
		If the map_name characteristic is not Null, then
		TP-DATA request has to be interpreted as a U-ASE service
		request. The valid U-ASE is derived from the map_name.

Page 416 (table 48):

	Change
		(TP-DATA indication) UD-TRANSFER indication
	to
		TP-DATA indication
		  (See table 49 on page xxx for details.)

Pabe 417: Add a new table 49 behind table 48. Relabel the following tables.

	Table 49. TP-DATA indication mapping
	----------------------------------------------------------------------
	OSI TP Service            CPI-C Calls, Parameters, and Characteristics
	  Parameters
	----------------------------------------------------------------------
	TP-DATA indication        Completes an outstanding
	  User-Data                 CMRCV - Receive 
				  and maps to the buffer parameter and
				  (after some conversion) to the map_name
				  parameter of
				    CMEMPN - Extract Map Name.
	----------------------------------------------------------------------
	TP-DATA indication is only a template. In a real environment it
	is replaced by a matching U-ASE service.
	UD-TRANSFER indication maps to a null map_name.
	Any other U-ASE indication maps to a non-null map_name defined
	by the local system.

Make the same changes in chapter D.3.
