1:1 Timing, Communication, and Control Card Redundancy

First Published: January 8, 2009

Last Updated: March 20, 2009

 

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.

Contents

Prerequisites for 1:1 Timing, Communication, and Control Card Redundancy

  • Two TCC cards must be installed in the Cisco RFGW-10 UEQAM chassis in slots 13 and 14.

Restrictions for 1:1 Timing, Communication, and Control Card Redundancy

  • Both the TCC cards should synchronize its clock with the same DTI server.

Information About 1:1 Timing, Communication, and Control Card Redundancy

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.

How to Configure 1:1 Timing, Communication, and Control Card Redundancy

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).

Initiating Timing, Communication, and Control Card Switchover

To force a switchover from the active TCC to the standby TCC, use the following command in privileged EXEC mode on the Supervisor:

Router# redundancy tcc-group switchover from slot [slot]

Displaying the Redundancy Status of a Specific Timing, Communication, and Control Card

This section describes how to display the redundancy status of a particular TCC. The commands are executed on the Supervisor.

SUMMARY STEPS

2. show redundancy tcc slot [slot]

DETAILED STEPS

Command or Action
Purpose

Step 1
enable
 

Router> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2
show redundancy tcc slot [slot]
 

Router# show redundancy tcc slot 13
