Alias and Call Routing Configuration: Overview

Overview

AI296 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 AI296 is in switch mode, the alias table is stored on AI198. When 
AI296 is in standalone mode, the alias table is stored in AI296’s local memory. For 
more information about alias translation and macros, see sections 

.

 displays a typical call processing data flow scenario where AI296 is used.

Figure 8-1   Call Data Flow

, an X.25 protocol call is coming into AI296 card A and needs to pass 

over the IRB and be sent out AI296 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 AI296 card A as an X.25 packet. Refer to 

 

for information about X.25

2. The data travels upstream and is converted into a TCP call.

3. The data starts downstream through the AEPN protocol option to preserve the 

packetization. Refer to 

 for information about the AEPN 

protocol.

4. The data is sent out AI296 card A over TCP on the IRB.
