Bandwidth:
o
3kbps of control data for each equipment and 1kbps additionally for each alarm.
o
Streaming audio channel according to the audio format protocol (configurable):
- Note: Control (without alarms) + number of simultaneous channel * Type of format protocol = Bandwidth
o
RAW PCM 48KHz, 4 channels, 100 equipment (3kbps * 100Eq.) + (4CH * 768kbps) = 3.4 Mbps
RAW PCM 48KHz, 4 channels, 50 equipment.  (3kbps * 50Eq.) + (4CH * 768kbps) = 3.2 Mbps
o
o
RTP G.711 A-LAW 8KHz, 4 channels, 100 equipment. (3kbps * 100Eq.) + (4CH * 64kbps) = 0.56 Mbps
RTP G.711 A-LAW 8KHz, 4 channels, 50 equipment.  (3kbps * 50Eq.) + (4CH * 64kbps) = 0.4 Mbps
