We are proud that Rhino is part of the Asterisk community.

Each Rhino is fully compatible with Asterisk; our channel banks feature the Rhino-only automatic setup option called "Auto T1" making installation a breeze.

Reduce the cost of your Asterisk system with the Rhino Channel Bank.

With the Rhino you can use your current analog phones and wiring in conjunction with leading edge Asterisk technology-- without upgrading to new expensive internet capable phones. This way, internet phone calls can still be made with the equipment you are already using.

Single Port (1-Port) Failover Card - Digital or Analog

Failover Pictorials

Standard Features

Providing reliable, flexible, and leading-edge solutions for a demanding industry.

 

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).

 

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 microcontroller 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 microcontroller by regularly sending an “OK” (watchdog) signal when Asterisk is running. When that “OK” is not received, normally when Asterisk fails, the microcontroller automatically switches ports to the failover device after a user defined duration. 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.

 

In digital mode, either an Ethernet or a T1/E1/J1 line can be switched, since all eight wires are routed straight through on the failover card to either the A or B port. In addition, in T1/E1/J1 mode, port 2 of the failover card is designed to be used with digital monitoring systems, with wires 1-2 and 4-5 connected from port 1 to port 2 through four 470 ohm resistors.

 

Rhino designed products are tough. In case of trouble, our technical support staff is ready to give you the support you need. Our 5-year, limited warranty means that you can be confident that Rhino will always work hard in your Open Source Telephony application.
