The codec
Home
screen indicates failover to a USB device has occurred by displaying
(F)
in the
Cxns
display. The audio file will play continuously in loop mode until a new connection is created.
Backup USB failover will continue as you attempt to dial a new connection and only ceases when a
successful reconnection is made.
Important Note:
·
USB backup audio is only sent to the outputs of the local codec to which a USB drive is
attached. USB file audio is not sent to encoders and cannot be transmitted via an audio
stream to another codec.
·
The USB drive can be inserted or removed at any time as long as the codec is not
already playing audio in failover mode. Removing the USB drive while audio is playing
from it will result in poor audio quality and should be avoided. If it is removed
accidentally you must reboot the codec to ensure USB failover will work in future.
Caution:
Do not attach a bootable USB drive to the
USB HOST PORT
or the codec will
attempt to reboot using the USB drive instead of the codec if the codec is repowered. To
ensure a drive is non-bootable, remove all system partitions and format the device without
system startup files.
Forward Error Correction (FEC)
FEC transmits a secondary stream of audio data packets over a single connection. If packets are
lost or corrupted over the connection then replacement FEC data packets can be substituted to
replace them.
Note: FEC should not be confused with SmartStream PLUS. FEC packets are sent over a single
data stream connection, whereas SmartStream PLUS dual redundant streaming transmits two
completely redundant audio data streams. FEC is also a subset of features within SmartStream
PLUS, which means you can configure SmartStream PLUS dual redundant data streams and also
configure FEC on each of these data streams. For more info on FEC see
Configuring Forward Error
Correction
.
Auto Reconnect
Auto Reconnect is the simplest form of connection backup whereby the codec will redial a lost
connection continuously until it is either:
·
Re-established, or
·
Dialing is manually stopped.
Auto reconnect can be enabled when configuring a codec program designed to dial another codec or
codecs. See the procedures for configuring different programs
using the web-GUI
for more
configuration details.
