DISH NETWORK DishComm Modem DishCOMM allows enabled receivers to share one phone line connection. Adding a phone outlet or wireless adapter is not necessary as it works over the home's electrical wiring. It does not eliminate or replace the phone line requirement. DishCOMM may not work through power strips or some UPS boxes. Enabled on the ViP622 with L401 software and the ViP211 with L436.
