8. Click on the T1/E1 Assignment subsystem in the DACS Configuration Menu. You will see the appropri-
ate three time slots statically mapped between WAN port 2 and WAN port 3.
Setting the clocking source
This section configures the Main Reference and Fallback Reference Clock for the Model 2604 DACS. You can
choose any of the WAN ports, an internal oscillator or an externally provided clock for the system clock in the
DACS. The Main Reference provides the DACS’s system clock unless it fails or is disconnected. Should this
occur, the Fallback Reference will be the clocking source for the DACS’s system clock.
Do the following to set the clocking source:
1. Click on
Clocking
on the
Configuration Menu
.
2. Connect your T1/E1 WAN connection to WAN Port #1 on the rear panel of the DACS. Assuming this is
the WAN link you wish to use as the Main Reference, set
Main Reference
to
wan-1(1)
(see figure 23).
Figure 23. System Clocking Configuration window
3. Set the Fallback Reference to none(0) if you have no other T1/E1 WAN links for connection to the
DACS. Otherwise, select the appropriate WAN port under Fallback Reference.
