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
).

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.
