ONT: Optical Network Terminal - An ONT is a media converter that is installed by the fibre optic service provider either outside or inside your premises, during installation.
Some ONTs have a backup battery to provide service during electricity outages. It may or may not be installed by the provider. The battery may also fail. I would make sure the ONT has a battery installed and that it works. It should be tested every few months and replaced when needed.
Just to clear things up,
is posting about his experience with fibre to the home on Bell Aliant. Most Telus customers have the last mile on copper and won't have an ONT. A UPS for the Actiontec will allow the internet to keep working for brief power outages. The fibre cabinets located in the neighbourhood have battery backup which will eventually run down in an extended power outage.
Thanks everyone. that is why i asked the experts. I do not have fiber ...standard 25/5 DSL .. I am about 100ft from the corner Telus box.
Since as far as i know plain old telephone works during an outage i figured maybe DSL would as well but wasnt sure.
guess there is only one way to find out for sure. but no more wind storms from hell please
Standard DSL modem/routers work fine with a UPS. Look for one that has a long run time under low load conditions. APC has some models that are suitable. There may be others. Costco usually has a couple of APC UPS units for a good price.
I have a UPS that powers the router, VOIP, and cordless phone base station. The UPS is a cyberpower 1350AVR... the estimated run time is 87 minutes. Never been tested though as our power here is pretty stable even during the last wind storm that knocked over a lot of trees. At work, I have another UPS that is an APC 1000 that powers my computer and monitor for 60 minutes so that one could power the router for a couple of hours at least.
