Comtech Redundancy Switches
are a companion product for use with Comtech EFData CDM-500, CDM-550 or
CDM-550T modems. Its purpose is to continuously monitor a pair of modems
in a redundant configuration, so that the unit automatically switches data
and IF signals from the failed unit to the standby unit if an equipment
failure or undesired traffic condition occur. In this manner, traffic
paths are fully protected, and the system operator can have increased
confidence that equipment failures will not adversely affect system
availability.
Cross Technologies Protection
Switches provide Auto, Manual, or Remote relay switching between CH1 and
CH2 clock signals (RS232C or RS422). Powered by redundant 90 - 260 VAC
power supplies, and housed in a 1RU chassis.
AnaCom's Protection Switch
System provides a high reliability 1 for 1 Hot-Standby configuration for
the ANASAT C and Ku-Band transceivers. 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 RS232/1485
interface cable is required to interface to indoor computer/dumb terminal.
