(DPL)
The DPL interface is composed of two ports—a full duplex asynchronous serial link for control
messages and a PCM digital audio link for audio traffic. The protocol used on these ports is
made available to application developers only on a case-by-case basis and after appropriate
non-disclosure agreements and/or license agreements are executed.
