10.6.8 CnC-APC Redundancy Support Notes
1. The initial release of the CnC-APC feature (in CDM-625 Firmware Version 2.0.2) fully
supports 1:1 redundancy. Note that, as is required with standard CnC 1:1 redundancy
operation, a PMSI cable is required to connect the two units in a 1:1 pair.
Sect. 5.2.1.8.4 CONFIG: CnC
PMSI-Control (Chapter 5. FRONT PANEL
OPERATION)
2. At this time, 1:N redundancy in the CRS-300/CRS-500 is not yet supported – a firmware
update for these switches will be available in the future. Please consult Comtech EF Data
Technical Support for updated information.
