Re: Upstream noise filter Yup our boxes return on 8.096 MHz. I guess it has a small window to xmit on, because another provider in the area using Moto boxes xmit on 10 or 11 MHz IIRC.
As far as downstream our boxes read OOB data on 104.2 or 104.5 (Can't remember exactly), and the other providers reads OOB data on 75.25 MHz.
I'd rather have them reconfigure our system to read OOB on 75.25 MHz, because reading it at the 104 MHz frequency effectively knocks out channel 97 from being used for anything (Analog or Digital).
I heard that some older Moto boxes had the frequencies hard coded, so if they are out in the field I guess they cannot change the OOB and return frequencies in our system. The newer Moto boxes are more agile and have a 10 frequency channel selection that they "Hunt" for OOB for, then the OOB tells the box what freq. the return channel is on. |

Decatur, GA | I went back and read the diag menus again on my Comcast/Motorola DVR DCH3416 and it deos indeed have OOB at 75,25mhz, above the 60MHZ limit of the filter.
However, it also clearly lists under upstream status "center frequency 10.976 mhz". Why wouldn't that be blocked since its above 10 and below 60? |

The OOB is the frequency that the box gets all its data from the headend on. Whenever there are guide updates, softeare updates, etc they all get broadcasted over that 75.25 freq. 55Mhz and up is the forward so if you blocked that you would lose some analog video as well. |
