When I worked for Verizon on the mainland our fiber to the home service (FIOS) included a battery that kept basic phone service working for about 4 hours during a power outage (assuming, of course, that the problem wasn't a downed cable). The Hawaiian Tel offering does not include the backup battery in their regular package, but I'm pretty sure you can order it as an add-on for a higher fee. When we got our fiber service installed here, we figured our cell phone was an adequate backup during outages.
