Accessing Parental controls on cox internet

Accessing Parental controls on cox internet - I have just been given a replacement  Tel modem Wifi router box which is the Arris Tg1682 G "panoramic" Modem for tel & Internet but cannot find any parental controls.  Cox has the McAfee cox security suite plus download However the site says the parental controls were discontinued in Sept 2015 I have spent sever hrs n days with cox,Arris & Motorola and each say the other is responsible support but both Arris and Motorola tech have no info on this router as COX is responsible to provide support -HELP!!!
