…."need not operate over the entire data signaling rate range specified nor be limited to 10Mbps. They
may be specified to operate at data rates to satisfy specific applications. The upper bound is application
dependent and beyond the scope of this standard. Maximum signaling rate is typically limited by the
following: ratio of signal transition time to the unit interval, maximum allowable stub length, and the
bandwidth of the interconnecting media."

PROFIBUS (Process Field Bus), developed subsequently, had several impacts on the electrical (physical)
layer including an increase in the receiver noise margin, to allow the bus to be used in an extremely noisy
(i.e., EMI-rich) environment. This was accomplished by increasing the minimum differential voltage on the
bus. The ISO1176T has been designed specifically for these types of environments. The two standards
are indeed very similar.
