sales field training TN3270 & TN5250 RF Universal Gateway solution

sales field training TN3270 & TN5250 Segmented RF solution Segmented could be through a router within a building or campus environment, or over a WAN

sales field training Required TN Config. Information Host IP address/addresses Subnet mask Terminal IP addresses Universal Gateway IP address/addresses –If used Router (gateway) IP address –If used Access Point IP addresses –If using IP on Access Points

sales field training TN 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 connected
