2 Clock Cable Connections
Use the clock cascading cables to connect clock and time
interfaces between the master and slave subracks. Use the clock
cascading cables to connect clock interfaces between NEs and
use the straight-through cables to connect time interfaces. For the
cables used to connect the OptiX OSN 8800 T16 to other
equipment, see "Clock/Time Cable" in the Hardware Description.
The shielded cables without protection boot are used
for transmitting clock signals.

NOTE
The following figure
shows an example
to illustrate the
clock cable
connections
.
1. The cables are connected in a similar way in multi-
subrack configurations. The only difference lies in the
number of cascaded interfaces.
2. The cables are connected in a similar way in multi-
subrack configurations. The only difference is the board
where the clock interface is located.
