Windows device driver information for Sony Ericsson Master Port

Sony Ericsson Master Port has two media ports connected to it: the downstream and upstream ports. The media stream flowing to the downstream port and used for sending direction is called the 'encoding' while the media stream flowing to the upstream port and is used for receiving direction is called 'decoding'. Imagine the downstream as stream to remote endpoint and upstream as the local media port. The media flowing to the remote endpoint (downstream) needs to be encoded before it is transmitted to the remote endpoint. Sony Ericsson Master Port internally has an instance of Clock Generator, which provides the essential timing for the master port. The Clock Generator runs asynchronously and whenever a clock tick expires, a callback will be called and the master port performs the following tasks: 1) it calls get_frame from the downstream port, 2) it gives the frame to the upstream port by calling put_frame to the upstream port, and 3) it performs the same task, but on the reverse direction (i.e. get the stream from upstream port and give it to the downstream port). Because master port enables media stream to flow automatically, it is said that the master port supplies Clock/Timing to the media ports' interconnection.

Sony Ericsson Master Port has Time Division Multiple Access (TDMA) that delivers digital wireless service using time-division multiplexing (TDM). A radio frequency is divided into time slots and the slots are allocated to multiple calls. In this way, a single frequency can support multiple, simultaneous data channels. TDMA is used by the GSM Digital Cellular system. It also contains individual conversations that are encoded with a pseudo-random digital sequence. Many conversations are carried simultaneously by sending all communications in groups of bits mixed together and tagging each group that belongs to a specific communication with a different code. Each communication can therefore be reassembled in the correct order at the other end, using the unique codes attached to particular groups of bits.
