Select Add a SmartStream PLUS Connection to configure redundant IP streaming.
Alternatively, click Next to configure Auto Reconnect or a failover connection, whereby the
alternative connection is dialed if the primary connection fails.
By default, primary IP streaming is via LAN1. To achieve the maximum level of redundancy
select Secondary to configure redundant streaming from the secondary IP port LAN2. The
redundant stream uses Remote Audio Port 9001 by default and the Local Audio Port
allocated is Automatic. Note: Automatic indicates that the codec will arbitrarily allocate the

delay the sending of FEC packets for a predetermined period after the primary audio
stream's packets are sent. This will increase the likelihood that the FEC packets will
take an alternate route to the primary stream's packets. This means that if primary
audio stream packets are not received at the remote codec, there is a good chance
that FEC packets taking an alternate route will be received and replace them. When
a FEC percentage lower than 100% is configured, FEC packets are automatically
delayed based on the ratio of primary packets to FEC packets sent at the selected
setting.
