Genie Distribution Backup Options
Tieline codecs feature highly advanced backup and redundancy options to maintain reliable audio
codec streaming. These include the options outlined in the following table:
Tieline Audio Codec Backup Features
Backup
Option
Transport:
IP, ISDN or POTS
Time
Required
to
Respond
How to Enable
SmartStream
PLUS
IP Only
(Note: concurrent packet
stream
sent;
codec
detects IP packet loss or
delayed packets)
No
time
delay
-
simultaneous
redundant
streaming
Enabled in dialing codec
program; configures local
decoding,
or
remote
decoding via session data
Fuse-IP
IP Only:
multiple
IP
interfaces are
bonded
and
data
is
shared
across interfaces
No time delay if interface
is
lost;
immediately
adjusts to existing network
data capacity
Configure
multiple
IP
interfaces and create a
Fuse-IP "Tunnel" prior to
dialing destination codec
On-demand
(cold) Failover
All transports
(Note:
codec
detects
loss
of
data
or
connection and redials
the backup connection)
User
configurable

during
program

is
equal to detection time
plus the time required to
dial
the
alternative
connection
Dialing codec program
monitors streaming and
manages failover
Output Audio

All transports
(Note: enabled by loss of

configuration.
Delay

equal to detection time
and

Enabled
in
a

program.
Output Audio
Source: HTTP
Connect to an Icecast
media server streaming
from a specified URL.
User
configurable

parameters
during
program
configuration.
Delay
is
equal to detection time
and

specified.
Enabled
in
a
codec
program.
Output Audio
Source: Input
Input audio is looped to
the
physical
codec
outputs.
User
configurable
detection
parameters
during
program
configuration.
Delay
is
equal to detection time
and
audio
threshold
specified.
Enabled
in
a
codec
program.
FEC
(Tieline
FEC
or
RFC
compliant
FEC)
Decoding codec detects
IP packet loss or delayed
packets.
Note:
Only
Tieline Music and Music
PLUS can be used for
Tieline FEC.
No failover time delay as
packet
replacement
occurs in real-time. Note:
RFC compliant FEC can
be configured to send
100% FEC at a specified
delay if desired.
