Example 2
Another card such as the Patton Model 6511 is the clocking master and your 2616RC is a secondary or slave.
This example assumes you will use the system clock as the main reference and WAN port #1 as the fallback ref-
erence. To define the clocking source, do the following:
Note
If there are two or more ForeFront TDM cards (6511RC, 3096RC,
2616RC, 3196RC) installed in the chassis (or chassis segment in the
6U chassis), only
one
card can be set as the master clock. Another
may be set as a secondary clock, although it is not necessary. All
remaining cards must be set as slaves.
1.
Connect a T1/E1 WAN line to WAN port #1 through the 2616RC’s WAN port cable.
