Question related with DAUD Message

Sigtran Experts

	I was looking for some help related with how to set the DAUD
message, I was reading some message from HS Jang related when the ASP need
to use the DAUD message, explain as follow

Let me summarize about DAUD in SUA ASP with your postings and my
understanding. first of all,
 1) ASP does not need to send DAUD in normal situation. because SCCP in SG
cares it with its mechanism and inform the ASP of the changes in DPC/SSN
with SSNM message. i.e. the state information about destinations are
synchronized all the time.
 2) the only time ASP needs to send DAUD is when the ASP is recovered from
isolation because ASP has no state information about destinations now. ( but
this is also not necessary for normal operation of data transfer. it is only
necessary when ASP really wants to know the state information of
destinations for example, in the respect of OAM or something ) 
3) there are mentions about sending DAUD periodically in RFC but it is
somewhat wrong. 
	
	Now base on these explanation and related with point 2, send DAUD
message when the ASP is recovered from isolation, my question is there is
any rules in other to how to send these point codes?? do we have or must
send multiple messages with one point code information per message, or send
just one message with all the point codes information???

	The main idea here is understand if I have a system with multiple
point codes, for example 25 point codes, how the standard said we need to
send the DAUD message, just one message with all the point codes inside or
25 single messages with just one point code per message.

I really appreciate your help on this question

Best regards
