FD182 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 FD182

failover box for BRI/PRI answers it. The FD182 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.

FD182 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 FD182 will automatically switch to the redundant

server.
