CRS-300 1:10 Redundancy Switch
Introduction

CRS-300 Compatibility
Table 1-1 shows the Comtech EF Data modems that are compatible for use with the CRS-300
1:10 Redundancy Switch.

Compatibility Notes:
1) The CDM-625 and CDM-625A Advanced Satellite Modems, with available CDM-600
Emulator Mode, serve as operationally transparent replacement units for the CDM-600/L
Open Network Satellite Modems.
2) The CDM-570A and CDM-570AL Satellite Modems can operate either in legacy CDM-570
Compatibility Mode or in the normal CDM-570A Mode. If the CDM-570A/AL is in a network
of CDM-570/Ls, then it will need to be configured for CDM 570 Compatibility mode.
3) The CiM-25, Comtech EF Data's low-cost Internet Protocol (IP) Monitor & Control (M&C)
interface for existing CEFD modems, is not compatible for use on modems operating within
a CRS-300 redundancy system. Taking this prohibition of use under further consideration,
the CiM-25 should not, under any circumstances, be connected to the Remote port on the
CRS-300's CRS-230 Controller card for control of the Switch and modems.
