Who maintains the phone modem?

Mediacom supplies and maintains the phone modem, which is called a multimedia terminal adapter ("MTA".) It is Mediacom's property. If there are issues with the MTA, Mediacom will send a technician to troubleshoot and replace it, if necessary. If you disconnect your Mediacom phone service, it is your responsibility to return the phone modem to Mediacom, or you will incur an unreturned equipment fee
