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.
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 local port value and send this information to the codec to which you
are dialing.
Important Notes:
· SmartStream PLUS redundant streaming over multiple IP interfaces mitigates lost
packets and provides IP network backup if an IP link is lost.
· Only one SmartStream PLUS connection per audio stream is supported with
uncompressed PCM, or when encoding with aptX Enhanced, G.711 or G.722 algorithms.
· Two SmartStream PLUS connections are supported per audio stream with Music PLUS
encoding.
· Up to three SmartStream PLUS connections are supported per audio stream when
encoding using Tieline Music, AAC algorithms, MP2, MP3 and Opus.
· TieLink only supports one SmartStream PLUS redundant connection for each audio
stream. TieLink also does not support uncompressed PCM connections, or encoding
using aptX Enhanced, G.711 or G.722.
