OverviewThis module converts between standard Audio HiFi formats\(analogue and SP-DIF digital\) and ATM 25. The device has two modes: local loop and duplex. In local loop, the audio output is the same as the input and in duplex the audio out is the ATM received data. Mode selection is via a control cell on VCI=49 or by IR. IR is sent and received on a separate ATM VC. |
