Goal
- To disable, power off, shutdown, or effectively prevent communication with the CM network when a delta (change) in signal levels is detected. Signal levels can be defined as Downstream signal strength in dBmV / Downstream Signal to Noise Ratio in dB or US: upstream signal strength in dBmV.
Background
- When a cable modem is added to or removed from a local section (i.e. building, drop) of the network, there will be a fluctuation in the signal strength of currently attached devices. By detecting this fluctuation, or delta, on a currently connected modem, the Cable Modem can ideally safely disable, power off, reset itself, or severe communication with the network.
HW / SW of Interest
- Motorola SB5101 + Haxorware.
Hi, all. Does anyone have an idea on how to accomplish this goal? Simply, I want a modem to monitor it's signal levels and remove itself (by some means) from operation on the CM network, when this delta is detected. My initial thoughts are a script running through Haxorware and the webshell. However, I am unsure of how to pursue this - or if someone has attempted this previously, through these means or another configuration.
All advice is appreciated,
