thank you for the info. I'll contact comcast about the power back up. Sorry there I wasnt clear about that. Since comcast provides a phone service, they have to have a way to provide service in the event of a power outage. One of the ways this is done is a battery inside the phone modem. The other way is thru a battery backup system for the equipment on the telephone poles.
In an area that has above ground service you may see large boxes about the size of a small file cabinet strapped to a pole. This is the power supply ( inserter) for the cable system . It takes power from the power company and drops it down to about 60 - 90 volts. This powers all of the amps and Nodes. There are also batteries inside here in case of a power failure. In extended power outages you may see generators attached to these boxes to continue to provide power after the batteries fail. All of my system guys carry a generaor or 2 in the back of their trucks just in case.
Hope that explained the backup system better |
