The IBUC redefines 1:1 protection switching. Instead of using a separate switching logic unit with its expense and complexity, Terrasat incorporates the switching logic and drivers into the IBUC itself.

Protected units monitor each other’s alarm condition and, through a simple switching junction box, make the decision to switch. The IBUC 1:1 package includes a cloning feature to simplify 1:1 setup. Terrasat’s 1:1 solution is a complete package with a dual-IBUC mounting bracket for convenient installation.

A 1:1 junction box mounts on the 1:1 mounting plate. Practically a passive unit, the junction box manages the functions of dividing the IF signal and routing signals through an Ethernet switch. It supports interface connectors and includes a bank of LEDs for visual indication of alarm conditions. The user interface is via web browser to embedded web pages, handheld terminal, RS232 or RS485.


  • FSK through TX IFL cable.
  • TCP/IP with embedded web pages.
  • SNMP agent
  • RS485/232 serial port.
