FD140 User Manual

 

 

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.

FD140 provides a reliable and flexible solution to Asterisk PBX.

FD140 Features

  • FD140 contains 4 E1 / T1 / BRI ports.
  • Easy installation; uses USB to connect computer or server. In order to provide more stable power supply, a USB interface for two connected hosts.
  •  Industry standard USB type B connector.
  • USB 2.0 and 1.1 compliant.
  • FD140 supports all OpenVox D series and B series cards, Digium and other compatible digital cards.
  • Two indicator lights, red and green. Two lights, said an Asterisk work normal, FD140 work. Only when green light said Asterisk hangs, FD140 switch to the backup phone.
  • Supports multiple FD140 devices in one system. Support the BRI or PRI circuit connection.
  •   Each network interface is divided into four mouth end, A, B, C, D, respectively, the interface of A and B are connected. Digital card.net client any end of the connection of A and B, redundant one interface can according to your needs, our TAP the card, to record, so as to meet your requirement for functional diversification. C and D connected to digital card of CPE, D is one end of the primary server, C is the standby server. For cable connection, LAN received any end of the A or B, D connected to the main network,C connect backup network.
