Chapter 1. INTRODUCTION
The CRS-100 1:1 Redundancy Switch (Figure 1-1) is a companion product for use with
Comtech EF Data CDM-500, CDM-550 or CDM-550T Modems. Its purpose is to
continuously monitor a pair of modems (in a redundant configuration) so that, in the
event of an equipment failure (or an undesired traffic condition), the unit will
automatically switch data and IF signals from the failed unit to the Standby unit. 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.
