# Operation Once the RDDRONE T1ADAPT and peripherals have been connected and powered up, the pre-programmed firmware make a connection by alternates which adapter device is the dominant controller on the T1 bus until a stable connection is established. In the absence of a signal, or the T1 connection is broken, the firmware resets the T1 PHYs and tries again to establish a link. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
