Timing, Communication, and Control Plus Card

On the Cisco uBR10012 router, the Timing, Communication, and Control Plus (TCC+) card acts as a secondary processor that performs the following functions:

•Generates and distributes 10.24 MHz clock references to each of the cable interface line cards.

•Generates and distributes 32-bit time-stamp references to each of the cable interface line cards.

•Allows software to power off independently any or all of the cable interface line cards.

•Drives the LCD module used to display system configuration and status information.

•Monitors the supply power used by the chassis.

•Provides two redundant RJ-45 ports for external timing clock reference inputs such as a Global Positioning System (GPS) or building integrated timing supplies (BITS) clock.
