To connect the router to external clocking devices, connect a cable with RJ-45 connectors
to each external clock input port:
Attach an electrostatic discharge (ESD) grounding trap on your bare wrist, and connect
1.
the strap to one of the ESD points on the chassis.
Plug one end of the RJ-45 cable into the internal clock port on the craft interface.
2.
Plug the other end of the RJ-45 cable into the T1 or E1 external clocking device.
3.
Verify that the LEDs for the external clock inputs are lit steadily green.
