DOCSIS 3.1 brings a good number of new technologies to the table which put together become the essence of this new powerful CATV standard. Here you will find these innovative developments as well as their related jargon explained below. DOCSIS 3.1 extends the Upstream band up to 192 Mhz and the Downstream band up to 1.2 Ghz (optionally up to 1.8 Ghz) with the objective of increasing network capacity.

The power of a digital channel is calculated using algorithms that evaluate the received energy through its entire bandwidth. The result of these calculations will differ from the vertical scale of the graph depending on the bandwidth of the signal that is being measured. These values will be more different as the bandwidth increases. How is this measurement calculated? How are we doing at PROMAX to guarantee and improve its accuracy?.

Coaxial wiring in new buildings (with no headend equipment installed has to be checked using a pilot carrier generator connected to the headend and a field strength meter certifying the reception levels in each outlet. For those facilities with installations in operation, each section can be checked in the same way, disconnecting and testing one section at a time.
