Composite source signals

Hi:

I am trying to make a composite source signal for test a echo
canceler, but i can understand a some thinks.
In the G.168 are defined the expresion for pseudo noise signal (G.168
Page 53 C.3-1), but I don't know

what are the values for W(k)? Thanks in advance
Jeronimo

What is unclear about:

"Each value W(k) (before filtering) is 152 680. It is calculated such that levels within a bandwidth of 20 kHz are the same for the voiced signal and the
PN sequence."

What is "152 680"? Is it 152680? or is it 152.680? (both don't seem reasonable). Could someone please clarify this issue?
