ASP Active

I had a question related to ASP Active message and the definition of AS:

The section 3.7.1 says:

   The ASP Active message is sent by an ASP to indicate to a remote M3UA
   peer that it is ready to process signalling traffic for a particular
   Application Server.  


And I read from the specs, that an Application Server can be a a virtual
switch element handling all call processing for a unique range of PSTN
trunks, identified by an SS7 SIO/DPC/OPC/CIC_range.  Another example is a
virtual database element, handling all HLR transactions for a particular SS7
DPC/OPC/SCCP_SSN combination.

In this context, here is the question:
Let's assume that we have the following stacks at the both the ends.


         ********    IP    ********
         *IPSP-A*          *IPSP-B*
         ********          ********

         +------+          +------+
         |SCCP- |          |SCCP- |
         | User |          | User |
         +------+          +------+
         | SCCP |          | SCCP |
         +------+          +------+
         | M3UA |          | M3UA |
         +------+          +------+
         | SCTP |          | SCTP |
         +------+          +------+
         |  IP  |          |  IP  |
         +------+          +------+
             |________________|



When the IPSP-A sends an ASP Active to IPSP-B, does it mean that the SCCP
ONLY (at Node A) is ready for receiving signaling traffic or even the
SCCP-User/Application (at Node A) is ready for Signaling traffic.

I believe that ASP Active was sent to receive the SCCP (at Node A) traffic
from NodeB. However, there can be a scenario wherein, at the same time, the
SCCP-User (at Node A) is NOT ready to send and receive traffic from NodeB.

Let me know if this interpretation is fine.
