This Docsis Root-Certificate is installed at the CMTS. If the ISP is using a "self signed" certificate for the cable modem he has to update the Manufacturer and cable modem certificate on the cable modem. This is not a easy part, besides the fact it's not standardized by the Docsis specification.
The fact that you know enough to propose this question proves that you understand more than anything ABMJR can even respond with.
I suggest you disregard his responses as they are of no benefit to anyone attempting to learn anything.
