The TTC (or TT&C) is the communication module of the CubeSats from SpaceLab. It is responsible to make the communication between the earth (a ground station) and a satellite, and is divided in two sub-modules: Beacon and telemetry.
The beacon is a independent sub-module who transmits a periodic signal containing an identification data (ID) of the satellite and some basic telemetry data. The telemetry sub-module is the main communication device. It has a bidirectional data link to receive telecommands from the earth and transmit all the requested data. The telemetry sub-module is controlled by an external device (as example, an OBDH module).

The TTC software and hardware releases are synchronized in order to garantee compatibility. Then, using diferent versions might lead to unpredictable behavior. Refer to the documentation for compatibility notes.
