Terrasat iBUC 1:2 Redundant System

Terrasat IBUC TX 1:2 Redundant System

Intelligent Transmit 1:2 Redundancy System for C, X, Ku & Ka-Band IBUCs

The Terrasat IBUC TX 1:2 Redundant System is an integrated antenna-mount transmit redundancy platform designed to protect mission-critical SATCOM uplinks. The 1:2 configuration allows two active transmit chains with one shared spare, maximizing uptime while optimizing cost and energy efficiency.

Supporting C-Band, X-Band, Ku-Band, and Ka-Band IBUCs, this system continuously monitors all IBUCs and automatically initiates switch-over when alarms are triggered. The integrated Intelligent Switch Controller Interface manages waveguide switching, L-band routing, reference detection, and alarm handling.

The IBUC TX 1:2 Advantage

Redundant internal 10 MHz reference available
Hot Standby Mode
Eco-Mode for warm standby (reduces amplifier power consumption)
User-configurable alarm thresholds
Factory pre-assembled for easy installation
Independent from LNB switching
Higher MTBF for SATCOM systems
Weatherized RJ45 Ethernet interface
Additional RJ45 port for Rx LNB integration

Ultimate Management & Control:

RS232 serial ports
Local web interface integrating all 3 IBUCs in one browser display
Intelligent Controller Interface monitors alarms & initiates automatic switch-over

How the 1:2 Architecture Works

Two primary IBUCs operate normally
One spare IBUC remains in standby
Intelligent interface module monitors:
    IF input paths
    10 MHz reference
    Amplifier alarms
Upon alarm detection:
    Waveguide (WG) switches are actuated
    Spare IBUC is routed to failed path
    Automatic switchover occurs

Result:
A compact, integrated 1:2 redundancy platform without external rack-based controllers.

Monitor & Control

Interfaces:

     Ethernet (RJ-45 J8 & J10)
    RS232 (PT02E-14-19S connector)
    AUX Ethernet
    Circular user interface connector
Alarm Relays:

     Summary Alarm Form-C Relays (A, B, C)
LED Indicators:

     2 Power supplies
    A, B, C Alarm
    Ethernet activity (A, B, C side)
    A, B, C online status
WG Switch Control:

     Intelligent Interface Module controls all WG switching

Typical Applications

Teleport gateways
Government networks
Air Traffic Control networks
Critical infrastructure uplinks
SLA-protected telecom systems

1:2 redundancy is ideal when:

Two active carriers must remain online
One shared spare is sufficient
High availability is required with optimized CapEx
