Synchronization splitter connections

The splitter connects to a timing source. Figure 3-6 shows the synchronization connections through a DSU/CSU (400A), and Figure 3-7 shows the synchronization connections through an ICSU (400A). Figure 3-8 shows the synchronization connections directly to the timing source (401A, 402A, 403A).
