[SI-LIST] : Effective terminating voltage

In Johnson and Graham's High-Speed Digital Design book in chapter 2
they
write of Vt being the desired effective terminating voltage. I assume
Vt
would equal Vcc/2 for CMOS logic, just because the math works out. What
is the
desired effective terminating voltage for TTL logic? What is the
reasoning behind
this?

Thanks,
