If you haven’t watched the full 20-minute video of TIA TR-42.7 Committee members Brian Celella and Todd Harpel discussing the drafting of TSB 5073why not?! We’re not here to shame you, though; we’re here to help. While we encourage you to watch that video for its insights into the process that will result in the publication of TSB 5073, we also invite you to watch the less-than-1-minute video on this page, which is an excerpt from that conversation. In this video, Leviton Senior Director Todd Harpel, who is editor of the TSB 5073 document, explains the difference between a standard and a TSB—and why network planners must use the two document types differently. Invest 49 seconds to watch. It’s worth it.
