Prior to this digitized communications system, all the data except for a few sites was transmitted by microwave links. In my 17 years working in Kap 100, or the old Vancouver VTS, and now Comox, Vancouver, and Tofino, I can recall probably fewer than five outages that were attributed to microwave link failures. We've had more outages based on the third party provider, and that is what the new CCS equipment is dependent on.
