The clock source configuration options enable you to select either the network
interface, a synchronous data port, the internal clock, the DTE Drop/Insert
(DSX-1) interface, or an external clock. If external clocking is selected, you must
use the clock rate configuration option to specify the clock rate.
Figure 3-12
shows some common clocking configurations. Two sample procedures for
configuring timing are given in the following sections,
Configuring for Network
Timing and Configuring for External Timing . For more information on
configuration options, refer to Appendix C, Configuration Options .
NOTE:
The external clock source is only available for 2-port and 4-port DSU/CSUs.
For carrier-mounted DSU/CSUs, the external clock provides timing for up to
eight slots in the carrier. Each Auxiliary Backplane must have its own external
clock input.
