etc. PRI2 cards such as the NT8D72BA are capable of supplying two
references of the same clock source. These are known as Ref1 (available
at J1) and Ref2 (available at J2) on the NT8D72BA.
The NT5D97 card is capable of supplying two references from each clock
source, for example, four references in total. NT5D97 can supply Clk0 and
Clk1 from Unit 0 and Clk0 and Clk1 from Unit 1. Either Unit 0 or Unit 1 can
originate primary source, as shown in
Figure 96 "Clock Controller - Option
1" (page 350) through Figure 99 "Clock Controller - Option 4" (page 353) .
There is one Clock Controller cable required for the DDP2 card, which
is available in four sizes; this is the NTCG03AA/AB/AC/AD. Refer to
“Reference clock cables” (page 331) for more information.
Table 147 "Clock Controller options - summary" (page 348) summarizes
the clocking options. Table 148 "Clock Controller options - description"
(page 349) explains the options in more detail.
