6.4 Connecting the time receivers
Time receivers can be connected via point-to-point connections (OUTPUT 1 to 3)
or via Ethernet.
Four Ethernet ports are available for the Ethernet connection and can be param-
eterized accordingly.
A redundant point-to-point connection can be implemented via OUTPUTs 1 and
2 when two SICLOCK TC 400s are used.

Point-to-point connections via an active current interface can be connected to
OUTPUTs 1 and 2 as shown in Fig. 6-6.
