Connect the Composite Clock
When required for digital services, connect the composite clock (Figure 22). You can cascade the
composite clock to other PG-Flex shelves. When cascading the composite clock to other PG-Flex
shelves, terminate only on the last shelf in the cascade.

Connect the secondary composite clock leads from the master clock source in the CO to
CC2_TIP and CC2_RING wire-wrap pins on the backplane.
Figure 22. Connecting the Composite Clock and Alarms
If the composite clock is connected, it must be terminated by connecting a jumper from CC1_TIP
to CC1_TERM wire-wrap pins, and from CC2_TIP to CC2_TERM wire-wrap pins at the last shelf
in the cascade.
