Quick Overview

Managing your open source telecommunication needs has never been easier than with Rhino products. The Rhino single port failover card provides a reliable method of positively managing analog or digital telephony sources (port 1) with one of two possible destinations; the normal operating destination (port 3), or the failover or redundant destination (port 4). In addition, a 2-pin header can connect directly to the PC motherboard and act as a failover reset source to restart the down PC.
Rhino 1PFAIL Failover Card Information:

Managing your open source telecommunication needs has never been easier than with Rhino products. The Rhino single port failover card provides a reliable method of positively managing analog or digital telephony sources (port 1) with one of two possible destinations; the normal operating destination (port 3), or the failover or redundant destination (port 4). In addition, a 2-pin header can connect directly to the PC motherboard and act as a failover reset source to restart the down PC.

The Rhino single port analog and digital failover is a self-contained, actively controlled, redundant switch with one input and two outputs (A-B). The failover card utilizes a powerful micro-controller that selects one of the two outputs depending on the condition of the main Asterisk server. The failover uses a loadable Asterisk module (.so) which communicates with the micro-controller by regularly sending an “OK” (watchdog) signal when Asterisk is running. When that “OK” is not received, normally when Asterisk fails, the micro-controller automatically switches ports to the failover device after a user defined duration. If the PC reset feature is enabled (it must be user enabled to operate in this mode), the PC will be reset. In addition, when power fails (USB power) the card automatically switches to the failover port.

In analog mode, the Rhino single port failover allows for the connection of one, two or three telco FXO lines (6 wires in an RJ11, or four lines in a RJ45 if specially terminated) between Rhino FXO ports and single line telephones. In the case of failure, the Rhino single port failover will connect FXO lines to the single line telephones, allowing for both incoming and outgoing calls to be handled on the single line telephones until the server can be brought back on-line.
