Whenever possible, determine the different service requirements first. It is often convenient to group similar services together in categories (e.g., voice systems, LAN, and other digital connections). Then, identify the individual media types and projected quantities required within each group. When requirements are uncertain, use worst-case estimates to evaluate backbone cabling alternatives.
