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
setting determines the clock source if this source is operational. If the
clock source fails, the
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)
