Redundancy Protection


Protection Switch

AnaCom's Protection Switch System provides a high reliability 1 for 1 Hot-Standby configuration for ANASAT® C and Ku-Band transceivers, ELSAT L-Band BUCS, and a combination of our ELSAT BUCs and an LNB. The Protection Switch System is ruggedly built for continuous outdoor duty in all types of environments. The Protection Controller is designed for simple, intuitive operation. TX and RX switches function independently.

The Protection System consists of a Protection Controller out-door box, and WR-229 and WR-137 waveguide switches for C-Band applications, or a pair of WR-75 waveguide switches for Ku-Band applications. Both switches include waveguide terminations for the off-line equipment. Only a single RS232/485 interface cable is required to interface to indoor computer/dumb terminal.


Compact, Functional Design

AnaCom's Protection System integrates all necessary functions into a small, highly integrated outdoor package which is designed to give highly reliable service in a wide range of environments.

The Protection Controller is fully contained in a single, small out door box with manual over-ride controls. Although normally intended for un-manned, automatic operation, the switch can be locally (or remotely) over-ridden to place a particular TX or RX switch (or both) on line and defeat the normal "switch-on-alarm" mode of operation. A single push-button (or remote command) returns the unit to completely automatic operation.

BITE Facility

To improve and simplify maintenance routines, an external terminal (or computer) can be connected to monitor a number of critical parameters without use of additional test equipment. These include:
  • Transceiver alarm status (TX, RX; A and B)
  • Switch alarm status
  • Switch position status
Controllable functions from the terminal include:
  • Force TX switch to the A side
  • Force TX switch to the B side
  • Force RX switch to the A side
  • Force RX switch to the B side
  • Restore Automatic operation

Comprehensive Monitor & Control

The Monitor and Control feature allows you to monitor and control the Protection Controller and both transceivers on the same RS232/RS485 M&C bus.

An MS DOS based Software provided with each Protection Switch for use in combination with a PC for monitoring and controlling both transceivers and the Protection Switch System from one computer display. Only one RS-232/RS485 cable is required from the computer to the outdoor equipment.
