Serial Protocol Conversion with Fallback Operation Diagram

In this example, the G530 provides protocol conversion between an SNA/SDLC network and a bisync network. The G530 accepts the SNA data in one port and immediately route the converted data to a second serial port for transmission to the other network. The G530 supports host and terminal emulation for all of the available protocols.

A second path is also illustrated in this diagram. The G530's Ethernet port is used when the second serial port is not available (no poll activity, etc.). When the alternate path is activated, the SNA data will be converted to TCP/IP for transmission to a second G530. This G530 will convert the data from TCP/IP to bisync for transmission to a different host. The IP connection can be through a HUB, router or other device.
