System Specifications
Terminal Services
Terminal services provide terminal-to-host connectivity with virtual terminal protocols
including Telnet, local-area transport (LAT), TN3270, and rlogin. Terminal services can be
used to connect to a modem in a modem pool for outbound connectivity.
Asynchronous Routing Services
Routing services enable the access server to route packets over LANs and WANs using
asynchronous interfaces to a remote LAN or WAN.
Protocol Translation Services
Protocol translation allows terminal services running over one protocol to be translated to
terminal services running over another protocol such as an X.25 packet
assembler/disassembler (PAD) to Telnet (using Transmission Control Protocol/Internet
Protocol [TCP/IP]). Protocol translation on the access server supports Telnet, TN3270,
LAT, X.25, and PAD.
