X.25 to TCP/IP Application
illustrates a common X.25 to TCP/IP application. X.25 network elements
are connected to a router network using a TCP/IP LAN.
Figure 1-8 X.25 to TCP/IP Application
illustrates the following events:
z
The OSS sends X.25 calls to AIswitch.
z
AIswitch converts X.25 calls to TCP/IP calls and sends them over the router
network.
network.
z
The router network carries the TCP/IP calls to AIfocus
TM
.
z
AIfocus sends the TCP/IP calls over the IRB to AI296.
z
Based on the AI198 routing alias, AI296 converts the TCP/IP calls to X.25 calls.
z
AI296 sends X.25 calls to the attached X.25 NEs.
Like other AIswitch line cards, AI296 terminates X.25 connections and extracts the
data from them. Unlike other line cards, AI296 can convert the X.25 connections to
TCP/IP connections across the IRB. The ultimate destination for these TCP/IP
connections may be one of the following:

When AI296 establishes a TCP/IP connection to an external device, the IP packets
are exported from AIswitch by AIfocus or by an AI router.
