For 1:2 redundancy systems, note that the functionality described for the 1:1 cable assembly also
applies to the 1:2 cable assembly; as shown in Figure B-5 and Figure B-6, the only difference is
that there is now a third connector, labeled “SSPA#2”, daisy-chained onto the cable assembly.
When a third Comtech EF Data ISSPA is connected via this cable assembly, it automatically
configures itself as ‘PRIMARY SSPA #2.’
A second six-wire cable assembly connects the Backup Unit’s ‘J7 | RF SWITCH’ connector to the
Waveguide Switch.
