  1. IntroductiontoTerminal Emulation

  2. Agenda • TNVT100/220 • TN3270 & TN5250 • SNA SDLC 3270 & 5250

  3. All TN Host Connections • TNVT100/220, TN3270, TN5250 • TN = Telnet • Protocol = TCP/IP • Transmission Control Protocol / Internet Protocol • Network Architecture = Ethernet • IEEE 802.3 Standards

  4. Unix Hosts IBM: RS6000 HP: HP9000 DEC: VAX PC: SCO PC: Linux Windows NT Requires Telnet Demon Georgia Soft Ataman TNVT100/220 DEC LAT: NOT SUPPORTED! LAT not compatible with TCP/IP on same Ethernet

  5. TNVT100/220 • HHP solutions supported • TN Client (direct connect) • Universal Gateway (controller)

  6. TNVT100/220 • Typical wired environment

  7. TNVT100/220 • RF TN Client (direct connect solution)

  8. TNVT100/220 • RF Universal Gateway solution

  9. TNVT100/220 • Segmented RF System Segmented could be through a router within a building or campus environment, or over a WAN

  10. IBM 3270 Hosts ES9000 S370 S390 AS/400 IBM 5250 Host AS/400 TN3270 & TN5250

  11. TN3270 & TN5250 • Solutions supported • TN Client (direct connect) • Universal Gateway (controller)

  12. TN3270 & TN5250 • Typical wired connection

  13. TN3270 & TN5250 • RF TN Client (direct connect solution)

  14. TN3270 & TN5250 • RF Universal Gateway solution

  15. TN3270 & TN5250 • Segmented RF solution Segmented could be through a router within a building or campus environment, or over a WAN

  16. 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

  17. 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 TN Client or Universal Gateway?

  18. IBM 3270 Hosts ES9000 S370 S390 AS/400 IBM 5250 Host AS/400 IBM SNA SDLC 3270 / 5250

  19. IBM SNA SDLC 3270 & 5250 • Host Protocol = SNA • SNA: Synchronous Network Architecture • *** Synchronous *** (requires external clocking) • Host Network Architecture = SDLC • SDLC: Synchronous Data Link Control • V.24 connection, RS232 38400 BPS • V.35 connection, 57600 BPS • Star topology from controller to terminals • Token Ring • Not currently supported!

  20. IBM SNA SDLA 3270 & 5250 • Controller based solution • 3270 Controller • 3274-51C cluster controller • 16 terminals per controller • Multiple controllers definable • 5250 Controller • 5294-1 cluster controller • 8 terminals per controller • Multiple controllers definable • 3270 Terminal • 3278 Model 2 emulation • 5250 Terminal • 5251 Model 11 emulation
