Your conventional all-copper-wire-to-the-Central-Office phone will fail exactly in the same way. What do you think powers them during an "extended electrical outage"?? Your POTS phone doesn't need any power from your home. it is powered from the phone company. The central office has heavy duty battery backup and generators. And the neighbourhood nodes have batteries and the telco then rotates portable generators to recharge those batteries. problems occur when you have a truly widespread outage where the telco doesn't have enough portable generators to move around to recharge all neighbourhood nodes. The solution is to use the telco's copper as a power source to power the fibre link and one phone. This way you benefit from the telco's UPS systems and don't need your own. |
