The UCCM modules came from Samsung WiMAX radio systems.  It looks like 
they OEM'd the boards from both Trimble and Symmetricom.  "UCCM = 
Universal Core Clock Module"  UCCM-P = "Universal Core Clock Module - 
Plus".  I managed to find a system description document that mentions it 
two or three times.  No details, though.
