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]]> http://www.dslreports.com/forum/remark,22497521 Thu, 04 Jun 2009 18:21:02 EDT Re: catv converter w/indoor antenna http://www.dslreports.com/forum/remark,22496254 The Q : I have a simple manual A/B switch hooked up to my TV set so that I can switch over to an OTA indoor antenna to watch broadcast signals if necessary.

A = Comcast converter box
B = Digital to Analog OTA converter with indoor antenna source

It's helpful if the cable ever goes out or if I want to compare PQ.

You would not get any usable signal from your cable provider from OTA. Comcast does have a backup system for providing their signal in the event of a power outage, so hooking your TV and cable box to the generator would still give you tv. Exceptions to this would be if there is a severe outage where the cable line is broke, damaged or lying in the street.]]> http://www.dslreports.com/forum/remark,22495131 Thu, 04 Jun 2009 11:07:16 EDT catv converter w/indoor antenna http://www.dslreports.com/forum/remark,22494967 anon : have a analog tv with motorola dct2224 from comcast. will this converter support a indoor antenna? during Ike I powered this tv w/generator using rabbit ears without converter as comcast was down.]]> http://www.dslreports.com/forum/remark,22494967 Thu, 04 Jun 2009 10:37:48 EDT
