The Timing, Communication, and Control Plus (TCC+) card acts as a secondary processor that performs lots of functions you need. It generates and distributes 10.24 MHz clock references and 32-bit time stamp references to each cable interface line cards. TCC+ allows software to independently power off any or all cable interface line cards and drives the LCD panel used to display system configuration and status information. It monitors the supply power usage of the chassis and provides two redundant RJ-45 ports for external timing clock reference inputs such as a Global Positioning System (GPS) or BITS clock.
