CPU Bus Unit service processing time (remote node)
The processing time will be as follows, depending on the CPU processing
mode settings at the CPU Unit.

The actual operating environment can cause transmission delays larger than
those calculated with the methods given here. Among the causes of longer
delays are the following: traffic on the network, window sizes at network
