FD140 Description
In most of the time, users need to reconnect the BRI/PRI line to a
redundant server maintained by UPS when main PBX Server is power off.
It may cause a little extra work for people who use simple and small PBX
servers. But for those who run complex PBXs in server rooms, it becomes
real problems.
How to eliminate this problem? The release of OpenVox FD140
failover box for BRI/PRI answers it. The FD140 can automatically switch
the BRI/PRI line to the redundant server when the power of the main
PBX server has been cut off and will automatically switch back to normal
when the power is on again. In this way, no more worries about getting
the BRI/PRI line connected to the redundant server when the main
server is down.
FD140 is controlled through an Asterisk loadable module
res_failover.so. This module keeps sending “running” signal to redundant
server when Asterisk is running. Once Asterisk is down or system power
is cut off, the module will not be able to send out the “running” signal to
FB40/FD40 and thus FD140 will automatically switch to the redundant
server.
