Why do the telecom transport equipments (like SDH) use only -48v or -24v dc?

two signals that have the same frequency.whn the amplitude of first is at its maximum the amplitude of the second signal is at half its maximum from the zero level. what is the phase shift between these two signals....
is it zero or 45 degree?
