Cisco RFGW-10 Components
In terms of the overall system high availability, the TCC cards work autonomously from the centralized
control mechanisms. Redundant TCC cards monitor each other's priority information so that when the
active card fails, the active card role is transferred to the redundant backup card without loss of data.
The following is a summary of the TCC card's functions and features:
•
Generates and distributes 10.24 MHz clock references and 32-bit timestamp references to every
cable interface line card
•
Drives the LCD module used to display the system configuration and status information
•
Proxy control mechanism (via supervisor cards) for the RF Switch Cards
•
Front Panel LEDs providing Status and Alarm Indicators
•
Provides two RJ-45 ports supporting redundant DTI server sources
