faces, environmental noise and other parameters) are controlled to
be better than minimally required, it may be possible to extend the
path length and device count.

meter).

[3] Values specified by data rate shall apply even if a slower data rate is

negotiated.

[4] Loads spaced at least eight inches (20.3 cm) apart (cables). (Refer
