The capability to receive the transmission of data from remote terminals allows a DATANET-30
system to perform as a:
•
Message switching center where messages and data are going from one remote terminal to
another
•
Remote data processing where data from remote stations is processed at a central com-
puter, and as needed, reports are sent to remote stations. The DATANET-30 can be
programmed to handle data traffic for a data processing center with equal facility that
it handles the administrative traffic normally associated with telegraph switching centers
•
Remote inquiry where an answer is generated by the computer and transmitted to the
station requesting
•
Automatic data accumulation and distribution to/from a variety of points for batch pro-
cessing by a computer
•
File updating where reports from remote stations are processed by a central computer
on a batch process basis
