Is there an adapter that will allow me to use my Netgear CM1000 with my cox Internet and Telephone? The CM1000 does not have a phone jack and I cannot swap itt out for another modem. I am paying for Cox telephone and cannot use it. I am willing to purchase the equipment. There has to be a way.
Cox will freely issue you a telephone modem (eMTA). Either go to a Solution Store or call them.
I don't believe Cox has a standalone eMTA, so it'll mostly likely be a combo DOCSIS-eMTA device.
Just to expand on your solution, there is two ways to do this. Either use a splitter, one for your CM1000 and one for your telephone modem. Or use a telephone modem for both internet and telephone. If you do it this way I would suggest the Arris TM3402.
