Does anyone out there have experience with V.35 interfaces.  What
are the real voltages that real equipment uses?

CCITT Recommendation V.35 for a balanced line driver says:

	"When terminated by a 100-ohm resistive load the
        terminal-to-terminal voltage should be 0.55 +- 20% volts
	so that the A terminal is positive to the B terminal when
	a binary 0 is transmitted, and the conditions are
	reversed to transmit binary 1."

However AT&T uses 1.1 volts terminal-to-terminal and claims it is
V.35.  I think AT&T misread the specification years ago; thinking
it said driver outputs should be +- 0.55 volts.  It seems that
the 1.1 V terminal-to-terminal voltage has become the defacto
standard.

Just to make sure it exists somewhere, does anyone out there know
of V.35 implemented with 0.55 volts?
