SARPs Date: ICAO Version 1.1 (ATNP/WGW1), March 1997

SARPs Language: english

Summary of Defect: The text on starting an association is deficient, 
especially in respect of its relation to the ULCS.

There is no specification of how to construct the calling end-system 
AP-title, and there is no reference to the table of 
A-Associate-request parameters.


Assigned SME: Sub-Volume 3 SME

Proposed SARPs amendment:

Add a new item (a) cross-referring to ULCS text on AP-title and change 
the existing text to call up Table 3.2.5-1; add a note for 
clarification, as follows:

"3.2.5.3.1.1.3     Upon the receipt of an Info-transfer request 
primitive, a Notify request primitive or Coordinate-start request 
primitive, the CF shall:
a) construct the Calling AP Title from the local ICAO Facility 
Designation according to the specification in 4.3.2;
b) invoke an A-ASSOCIATE Request primitive with the parameters 
specified in Table 3.2.5-1; and
c) enter the ASSOCIATION PENDING state.
Note.- To construct the Calling AP Title, the CF is assumed to have 
local knowledge of the ICAO Facility Designation of the AIDC-AE which 
it defines."
