OVERVIEW
Four Wire Audio Box
The Four Wire Audio (FWA) interface is a full duplex audio solution with optional E & M
signalling intended for connectivity to equipment requiring an analogue audio interface e.g.
Voice Frequency (VF) modems, or radio systems such as analogue base stations.
Additionally a single EIA232 (UART) interface is provided for end-to-end site communications
at 9600 baud.
The MiMOMax Four Wire Audio interface is provided for by an add-on Network Interface Box
(NIB) which communicates directly with a MiMOMax Radio Unit. The Four Wire Audio
interface is able to be co-located with the Radio Unit in the standard rack mount tray.
Four Wire Audio Solution Overview
The MiMOMax Radio Units plus Four Wire Audio interfaces provide a complete point to point
audio solution where low latency high quality audio is required. When paired with Radio Units
utilizing 16 QAM in a 25 kHz channel, 12 ms latency or better is achievable (A detailed
latency discussion is available in section 2.6)
