If the all the preceding settings are done correctly and the codec detects a lost
main connection, it will automatically switch to the selected
Standby
connection and the POTS
Failover profile
will become the active profile on
the codec
LCD
and within the connected codecs.
Important Connection Note:
If you don’t put the same phone number (etc) in both
Connection no 2
of the
ISDN profile and the POTS
Failover profile
, then if the failover connection is
initiated, it will not automatically change over to the second connection
running concurrently. Instead, it will dial the POTS
Failover profile
connection (this may cause up to 30 seconds delay to your program signal).
22.16.7.
Non-Concurrent Connections
If you do not want your failover connection to be concurrently connected (i.e.
connected while the main program connection is in use), then you wouldn’t
set
Connection no 2
as a
Standby
connection in your main program ISDN
profile. Just set the POTS
Failover profile
as per your dialing configuration
etc, and if the main ISDN program feed is lost, the POTS
Failover profile
will
dial the connection to connect.
22.16.7.1.
Another Reconnection Option
If you are using a single POTS connection, you could protect against a
loss of signal by setting the
Failover profile
to the same profile you are
using as your main POTS connection. Remember, if you decide not to
use
Failover profile
and you want the codec to reconnect after the loss of
a connection, you will need to either program
Automatic redial
or ‘check’
the
Auto reconnect
function which is within the
Unit Options
menu.
Please note:
The
Failover profile
facility is ‘grayed’ out and inactive until the
Standby
box is checked to enable the setting up of a standby connection.
Important Failover Footnote:
If you are using
Failover profile
we recommend that you should failover to a
different connection type than your main connection. For example if your
main connection is via an ISDN line, we recommend you failover to IP,
POTS or GSM etc. This will safeguard you in case your incoming lines have
been damaged or unplugged.
In addition, we recommend that you only use the
Music
or
Voice G3
algorithms for failover connections. This is because if you use other
algorithms to connect, you will need to manually change the profile setting at
the remote codec (
Remote profile
) in the event of a failover connection being
initiated. The remote profile can change automatically if you use the
Music
or
Voice G3
algorithms.
