The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Timing, Communication, and Control (TCC) card operates in 1:1 redundancy configuration where each TCC card has its own dedicated backup card in case of failure (hot standby mode). Only the active TCC card provides functionality in the RF Gateway 10 (RFGW-10) Universal Edge Quadrature Amplitude Modulation (UEQAM) chassis. The standby TCC card is accessible from other line cards, but does not provide any functionality.
Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the “Feature Information for 1:1 Timing, communication, and Control Card Redundancy” section.

The Timing, Communication, and Control (TCC) card is part of the Cisco RF Gateway 10 chassis. The TCC is 1:1 redundant and the standby will be a hot standby.
There is no TCC redundancy configuration command. The system automatically configures slots 13 and 14 in a 1:1 protection scheme (no user provisioning is needed for TCC redundancy).
To force a switchover from the active TCC to the standby TCC, use the following command in privileged EXEC mode on the Supervisor:
