TraffiControl
See the ingress that is present "underneath" an upstream cable modem channel.
As cable system upstream spectrum becomes more crowded with newer and better services, it becomes more challenging to troubleshoot the ingress and transient impulse noise that commonly interferes with upstream signal transmission. Up to this point analyzing this interference has been difficult at best, because the spectrum display shows the highest signal at any given frequency, and if things are working according to design, this will be the service signal. Using a "min hold" feature to eliminate the time division multiplexed signal and reveal the spectrum below doesn’t work well because the interference will be minimized as well, possibly even removing the transient interfering signal from the display by showing only the minimum measured levels at each scan resolution point.
The 860 DSPi TraffiControl option can be used to see the ingress that is present "underneath" an upstream cable modem channel, or any bursty signal. The optional feature uses DSP to sort out the traffic from the rest of the spectrum, with the display showing both the traffic and the noise and peak noise. (see figure above) The simple and comprehensive display enables a user to see what is currently happening, as well as capture peak interference levels of transient signals during the time that the measurement is being made.
The TraffiControl option is now available, option 0930081014. 860 owners with the latest firmware may activate the option in the field by purchasing a key code.
