Timing Communication & Control Plus Card

Part # UBR10-TCC+-T1

Product Description: Cisco uBR 10000 Utility Card controls the Cisco uBR10012 universal broadband router's Timing, Communication, and Control Plus (TCC+). It acts as a secondary processor that performs the following functions: distributes 10.24 MHz clock references to each cable interface line card, distributes 32-bit time stamp references to each cable interface line card, software to independently power off any or all cable interface line cards, the LCD panel used to display system configuration and status information, the supply power usage of the chassis, and two redundant RJ-45 ports for external timing clock reference inputs such as a Global Positioning System (GPS) or BITS clock.

When two TCC+ cards are installed, they are configured as active (primary) and backup (redundant). If the TCC+ card in the first slot is working at system power-up, it automatically becomes the active card and the TCC+ card in the second slot becomes the backup card. The TCC+ cards monitor each other's priority information, so that if the active card fails, the active card role is transferred to the redundant backup card without loss of data.
