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

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
