The bi-directional AIF-2S module supports the widely deployed AES3 digital audio standard which was originally developed by the European Broadcasting Union (EBU) and the Audio Engineering Society (AES). Following the AES-3id specification, the user interface (electrical) to the AIF-2S module is via a 75-ohm coax cable. Within the MD8000 network, each AES stream can have a single or multiple unique destinations. Each AES stream consumes 4.8Mb of bandwidth.
On the transmit side, the AIF-2S module accepts two channels of AES audio, encapsulates the signal into Ethernet frames with or without Forward Error Correction (FEC), and transfers them to the MD8000 SW-CNT modules. On the receive side, the AIF-2S module accepts Ethernet packets from the MD8000 Switch Controller (SW-CNT) and provides two unique audio outputs.
To improve audio transport reliability and resiliency, the AIF-2S module supports both Forward Error Correction (FEC) and Lossless/Hitless path protection switching. The front panel of the AIF-2S module features a comprehensive set of LEDs for monitoring the status and health of incoming and outgoing audio streams.
