Alias and Call Routing Configuration: Overview
7-2
Overview
AI232 uses aliases to route calls across the backplane of AIswitch. Each incoming 
call’s routing information must match an entry in the alias table, or else the call is 
rejected. When AI232 is in switch mode, the alias table is stored on AI198. When 
AI232 is in standalone mode, the alias table is stored in AI232’s local memory. For 
more information about alias translation and macros, see sections 
.
 displays a typical call processing data flow scenario where AI232 is used. 
Data flow can be upstream or downstream, depending on the direction from which the 
data originates.
Figure 7-1   Call Data Flow
, an asynchronous protocol call is coming into AI232 card A and needs to 
pass over the IRB and be sent out AI232 card B. Refer to the figure to follow the flow 
of the call.
The following events occur if the data flow is from left to right:
1. The data comes into AI232 card A as an asynchronous packet.
2. The data travels upstream and is converted into a TCP call.
3. The data starts downstream through the ASY protocol option to preserve the 
packetization. Refer to 
 for information about the ASY protocol.
4. The data is sent out AI232 card A over TCP on the IRB.
