24.16.6. Complex Failover Setups: The Standby Connection and
Failover Profile Relationship
A
Standby
connection can run concurrently with a main connection as a
backup program connection. Previous elements of this section of the manual
have discussed how to set up a connection. A
Standby
connection is set the
same way as other connections - the only difference is that you check the
Standby
box in
Tool
Box
to create the connection.
If you wish to use set up a
Standby
connection and utilize the
Failover profile
facility, you will need to ensure the following has been set up:
1. A
Standby
connection, i.e.,
Connection no. 2
, is programmed with a
phone number and the
Port
and
Codec channel
has been programmed
into the main program connection’s profile.
2.
Failover profile
on the main connection has been set to the profile which
will be used for the
Standby
connection.
For example, if your main program connection is via either one or two ISDN
B channels, a
Standby
POTS connection can be connected alongside the
main connection, but no audio will be sent unless the main connection fails.
Only then will the connection go active and an encoder be assigned to this
connection.
To assist in conceptualizing this, in the flow chart example below, the codecs
have been configured to have a main connection for program sound via an
ISDN B-channel and a
Failover
or
Standby
connection via a POTS
connection.
To set up this configuration, you need to set up the main ISDN Connection
no 1
as the primary connection. In
Connection no 2
set up the same
connection information as the settings in the
Failover profile
, in this case the
POTS connection. You need to ensure that the same phone number and
Port
is set up in
Connection No 2
of the ISDN main profile as the POTS
failover profile that you have set, and check it as the
Standby connection
.
