I am a bit concerned about the apparent limitations of our fiber optic phone service during a power outage. On the old copper line, the power could be out for a week or more during a major storm, but we could still make and receive calls on the corded phone. With "Digital Voice," however, we'll only have eight hours of phone service during a power outage. We are therefore considering switching back to the copper phoneline but keeping FiOS TV and internet.
Before we decide to switch back, though, I have a question. I have been told that one of the advantages of "Digital Voice" is that the fiber optic line attempts to find another source of power within that eight-hour time frame, and it usually succeeds. I cannot, however, find anything online to verify this claim. So, is it true? Does the fiber optic line normally "reconnect" with a power source to keep the phones running longer than 8 hours during an outage? If it's not getting any power from our house or the battery, how is this possible?
