If it were my system every customer who was not using the sub band would be filtered. However most system tech's are too lazy or stupid to deal with fixing the actual problem's they usually just drop the return pad to get that particular modem to work while they raise the entire noise floor for the whole node. As the one person said you have to roll a truck to take the filter off if the customer upgrades to me that is a small price to pay to make the system work properly. Of course if the system tech's for the most part were not lazy and worthless there would be no need for us contractors to come in to sweep and ingress the system. So for me I appreciate them being lazy and worthless.
