The Comtech 550 and 570 modems are being replaced by Teledyne Q-Flex modems in 2015. They are being shipped out now to vessels, largely preconfigured for drop in replacement use initially. At some point, they will need to have some more considerable changes made to their configuration so as to make use of their IP interfaces for data. However, that change will need to be coordinated across an individual beam. For now, initial installation will involve the serial interface between the modem and Cisco router.
