(see figure 15).
Figure 15. System Clocking Configuration window
The Clocking window is where the primary and secondary clocking sources that synchronize all DS0 channels
are configured. The DACS uses a single clock source for all DS0 channels. You select the clock for the DS0
channels from the following clock sources:
•
An internal oscillator
•
Any of the WAN ports
•
An external clock (accessed via the
Ext. Clock
3-position terminal block located on the rear panel of the
DACS.”
The
Main Reference
setting determines the clock source if this source is operational. If the
Main Reference
clock source fails, the
Fallback Reference
becomes the clock source to synchronize all DS0 channels. The
clock source is the system clock for the entire DACS.
Configuring the System Clock Settings
The following sections describe configuring the clock settings.
Main Reference (daxClockMainRef)
The
Main Reference
and
Fallback Reference
parameters have the same selections for system clock. Make sure
you choose different clock sources for the Main Reference and Fallback Reference. The following settings
are available:
•
