Connectivity Alternatives for Remote Users of the Maintenance Processor Subsystem(MPS). Addendum-1

摘要

A significant savings in the life cycle cost of providing connectivity to remoteusers of the Maintenance Processor Subsystem (MPS) has been shown to be technically feasible. Previous studies indicated a potential savings in excess of $900,000 by using an X.25/RS-232 communications architecture to link the MPS through the Data Multiplexer Network (DMN) to Maintenance Data Terminals (MDT). This report presents the results of testing an X.25/V.35 communications architecture. This architecture is superior in terms of cost savings, maximum data rates, and reduced quantity of X.25 links required. This report also recommends a speed configuration for the different communications links involved. with this architecture. These are the results of testing conducted by the Advanced Systems Technology Branch (ACD-350) at the Federal Aviation Administration (FAA) Technical Center....
