Data Communication and Terminal Controllers (DTC)
Data communication and terminal controllers (DTCs) are stand-alone
boxes that connect to the LAN to provide additional serial connections
for local or remote devices. Unlike serial interface cards, which
communicate directly with the core operating system, DTCs use
Telnet-TCP/IP protocols to communicate with the peripheral devices.
Therefore DTCs provide most, but not all, the same functionality. Two
types of DTCs are available:
• DTC 16MX telnet terminal server (J2063A), providing direct
connection for LAN, diagnostics, and up to 16 serial-connected
peripherals.
• DTC 16RX telnet terminal server (J2064A), providing routable
management in addition to direct connection for LAN, diagnostics,
and up to 16 serial-connected peripherals.
• DTC 72MX communications server (J2070A), providing LAN,
telnet access, X.25 access, and connection for up to 72
serial-connected peripherals via an asynchronous processor board.
DTCs must be configured by one of two DTC software products, HP
