10.4 COM 1 Interface

128 Digital Fault Recorder, SIMEAS R-PMU, Manual

E50417-H1076-C360-A5, Release 10.2012

10.4.4 X.25 Communication

X.25 data networks are public switched systems and are based on the internationally

standardized packet switching protocol X.25. These systems enable access to all other

national X.25 packet switching services that exist all over the world. The PADs (Packet

Assembly Disassembly) are required to disassemble the files into packets during

sending or to reassemble them to the source files upon receipt.
