5. The Streaming Ports
The two streaming ports (
ETHERNET A
&
ETHERNET B
) conform to the following specifications.
5.1
RAVENNA Net
All RAVENNA Net interfaces provide:
·
SMPTE 2110-30/31 AES67/RAVENNA: multi-channel digital audio-over-IP.
·
Per port: up to 128 bi-directional channels at 48kHz AND 96kHz.
·
Per port: up to 128 TX and 128 RX streams.
RAVENNA Net connections
must
be made via the streaming network (i.e. to and from a RAVENNA-compatible
network switch). This ensures that the network's PTP clock signal is available to all streaming ports.
RAVENNA streaming requires proper configuration and management of the data network. The network
must
use a suitable architecture; all components must support multicast (as opposed to unicast); a proper
Quality of Service (QoS) must be configured; and so on.
Please
DO NOT
attempt to connect RAVENNA interfaces using an unqualifying IP network, as correct
streaming operation cannot be guaranteed.
You can find more details about the data network requirements in the

·
1000, 100 or 10 Base-TX LAN;
1000 Base-TX
(Gigabit Ethernet) is recommended.
·
Cable Length: up to 80m.
