AS

Application Server. A logical entity serving a specific Routing Key. An example of an

 

AS is 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. The AS contains a set of one or more unique Application

 

Server Processes (ASPs), of which one or more is normally actively processing traffic.

 

Note that there is a 1:1 relationship between an AS and a Routing Key.

ASP

Application Server Process. A process instance of an Application Server (AS). An ASP

 

serves as an active or backup process of an Application Server (for example, part of

 

a distributed virtual switch or database). Examples of ASPs are processes (or process

 

instances) of MGCs, IP SCPs or IP HLRs. An ASP contains an SCTP endpoint and may

 

be configured to process signaling traffic within more than one Application Server.
