D M S -100 CompuCALL Interface Specification (Q218) 47
47
47
TotalBytesPC - total bytes per call (byte/call),
ByteToBit - bits in one byte (= 8),
Occu - planed CompuCALL message occupancy of
X.25 link (e.g. 60%).
Formula 2:
BandWidth (bit/sec) = CallsPS * TotalBytesPC * ByteToBit * Occu
Where: CallsPS - average calls per second (call/sec).
