X.25 to TCP/IP Application
Figure 1-8 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
Figure 1-8 illustrates the following events:
zThe OSS sends X.25 calls to AIswitch.
zAIswitch converts X.25 calls to TCP/IP calls and sends them over the router
network.
zThe router network carries the TCP/IP calls to AIfocusTM.
zAIfocus sends the TCP/IP calls over the IRB to AI296.
zBased on the AI198 routing alias, AI296 converts the TCP/IP calls to X.25 calls.
zAI296 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:
zAn IRB-connected line card in the same chassis, such as another AI296 or an
AI193-TXTM
zA locally connected TCP/IP host
zA remote TCP/IP host, indirectly connected to AIswitch using a router network.
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.
