Step Action Command Description
1. Disable
synchronization
switch
disable
synchronization
-switch
Prevent the system from switching synchronization
sources.
2. Busyout DS1
circuit pack
busyout board
UUCSS
Busyout the designated DS1circuit pack.
3. Remove cable
from DS1 circuit
pack
Remove the existing H600-307 cable from the backplane
slot corresponding to the designated DS1 circuit pack.
4. Remove ICSU Remove the ICSU from the designated DS1 circuit pack’s
amphenol connector.
Re-use the existing cable attached to the ICSU.
5. Attach splitter Plug the splitter into the same connector just vacated by
the ICSU.
6. Attach ICSU Plug the ICSU into the connector on the splitter.

Check that all Amphenol connections are good.
9. Secure splitter Secure the splitter to the carrier using the 4C retainer from
the ICSU.
10. Secure ICSU Secure the ICSU to the splitter with a long cable tie.
11. Terminate the
splitter ports J1
and J2
Insert a modular RJ45 plug in both ports J1 and J2. Do not
connect port J1 to port J2, but leave the other end of both
cords free. The modular RJ45 plug acts as an opening
plug and removes the 100-Ω termination from port J1 and
J2 on the splitter.
