It usually takes a cable company a year or longer to complete an upgrade. Most cable companies upgrade every 10-15 years. Some sooner -some later. We allow previous customers to trade in their old descramblers that they purchased from us for credit towards new equipment, providing that it is in good working condition. Back to top .
Most cable companies scramble all premium channels.
Some cable companies, usually older systems, will filter some movie channels. Filtering and scrambling are totally different methods and one has absolutely nothing to do with the other. A descrambler descrambles a scrambled signal. When filtering is used, the signal is not scrambled - it is being filtered. This requires something different.
