Model 3196RC T-DAC User Manual 3 • Configuring the T-DAC for operation
Unless it fails or becomes disconnected, the main reference provides the system clock for the 3196RC. Should
this failure occur, the fallback reference will be the clocking source for the 3196RC's system clock.
Example 1
Your 3196RC is the only blade in the chassis and must be configured as the system clocking master. This exam-
ple assumes you will use WAN port #1 as the main reference and WAN port #2 as the fallback reference To
.
define the clocking source, do the following:
1. Connect a T1/E1 WAN line to WAN port #1 through the 3196RC's WAN port cable.
2. Connect a T1/E1 WAN line to WAN port #2 through the 3196RC's WAN port cable.
3. Click the System Clocking hyperlink on the 3196RC Configuration Menu to open the System Clocking
Configuration page (see figure 26).

5. For Main Reference select wan-1(1).
6. For Fallback Reference select wan-2(2).
7. Click on the Submit Query button.
8. Select enable(1) to enable the fallback reference clock.
9. Click the Submit Query button.
Example 2
Another card such as the Patton Model 6511 is the clocking master and your 3196RC is a slave. This example
assumes you will use the system clock as the main reference and WAN port #1 as the fallback reference. To
define the clocking source, do the following:
1. Connect a T1/E1 WAN line to WAN port #1 through the 3196RC's WAN port cable.
