Digital Trunk Synchronization Slots (J37)
Two synchronization sources may be defined for the Coral IPx 800 system. One serves
as the primary source, and the other serves as a secondary synchronization signal
source. A total of six slots are factory set to accept digital trunk cards to operate in
slave clock mode. Two slots are located in the Coral IPx 800 main cage and the
additional two slots are pre-wired in each of the IPx 800 expansion cages. Card slot #4
in all cages is wired to operate as the primary external clock synchronization source
(marked PRM SYNC). Card slot #5 in all cages is wired as the secondary external clock
synchronization source (marked SEC SYNC). The expansion cage can house the
primary and/or secondary synchronization card in slots 4 and 5, respectively.
Figure 6-45 displays the jumper configuration for clock synchronization. For further
information, see
