Configure legacy protocols
Older protocols that existed before TCP/IP became dominant are often referred to as legacy
protocols. Examples of legacy protocols are X.25, SNA and LAPB.
Digi TransPort routers can connect to legacy networks such as X.25. They can also simulate a
legacy network so that equipment that, in the past, would have connected to a legacy network,
can connect to the Digi TransPort router instead. This means old equipment can be connected to
modern networks such as HSUPA.
This section covers configuring legacy protocols from the web interface or command line. It
covers the following topics:
• Configure Systems Network Architecture over IP (SNAIP) on page 500
• Configure TPAD parameters on page 509
• Configure X.25 parameters on page 521
• Configure MODBUS Gateway parameters on page 563
• Configure Protocol Switch software on page 567
