FA100 Description

Most of the time, users need to reconnect PSTN line to analog

telephone to make it work when the PBX Sever faces a power failure. It

may cause only 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 FA100

failover box solves it. The FA100 can automatically switch the PSTN line

to analog telephone when the power of the PBX server has been cut off

and will automatically switch back to normal when the power is on again.

In this way, you will no more need to worry whether the power is cut off.

FA100 is controlled through an Asterisk loadable module

res_failover.so. This module keeps sending “running” signal to FA100

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, thus

FA100 will automatically switch to the standby telephone.

FA100 provides a reliable and flexible solution to Asterisk PBX.

The picture below shows FA100 network ports connection, such as the

connection between Network cable, PRI, BRI and port A or B.

When Asterisk normally works, the PSTN signal goes:

1->LAN (red) 2->main network (green)

When Asterisk works abnormally，the PSTN signal goes:

1->LAN (red) 2-> Redundant network (purple)

If FA100 doesn’t receive the "running" signal from the Main Server, then

the internal circuits will be switched to Redundant Server automatically.
