There were three major components that made up the USAF communications system.  These were:

 

 

Model Number  Description  Further details 
HM510  Terminal equipment 

 

here 
HM560  Repeater equipment 
HM50  Baseband equipment  here 

 

The HM50 baseband equipment was used at the terminal equipment for modulating and demodulating the baseband for connection to the multi-channel carrier telephone circuits.

 

Examples of the promotional documentation of the HM500 series equipment at the time can be seen here.
