Glossary
Terminals can either be directly
connected to the DTC, or they can
be remotely connected through a
Packet Assembler Disassembler
(PAD). The DTC can be
configured with DTC/X.25
Network Access cards and
DTC/X.25 Network Access
software. A DTC/X.25 iX Network
Link consists of two software
modules: the X.25 iX System
Access software (running on the
host) and the DTC/X.25 Network
Access software (running on the
DTC).
