1.3 Features
1.3.1 Physical Description
The CDM-600/600L Open Network Satellite Modem is constructed as a 1RU-high rack-mounting
chassis, which can be free-standing if desired. Rack handles at the front facilitate removal from and
placement into a rack.
1.3.2 Compatibility
The CDM-600L Open Network Satellite Modem is fully backwards-compatible with the
CDM-600 modem. In turn, the CDM-600/600L is fully backwards-compatible with the Comtech
EF Data CDM-500, CDM-550, and CDM-550T
modems.
Being an Open Network modem, the CDM-600/600L is fully compatible with modems from other
manufacturers that are compliant with the IESS-308 / -309 / -310 / -314 / -315 specifications.
The CDM-625 Open Network Satellite Modem, with its available CDM-600 Emulator Mode,
serves as an operationally transparent replacement unit for the CDM-600/600L Open Network
Satellite Modem.
