ngTN Client or Universal Gateway?
• TN Client– 15 terminals or less– Lower hardware cost– Less hardware to fail– Less network traffic– Load configuration to
each terminal– Debug logs stored in
terminal
• Universal Gateway– Large or complex
systems– Holds all terminal
configurations– Dial in support
• trouble shooting• access to logs
– IBM SNA SDLC• Host not Ethernet
