Digital Trunk Synchronization Slots
Two synchronization sources may be defined for the Coral IPx 500 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 IPx 500 main cage and the additional
four slots are pre-wired in each of the IPx 500/800 expansion cages. Card slot # 4 in all
cages is wired to operate as the primary external clock synchronization source (marked
SYNC-PRIME). Card slot # 5 in all cages is wired as the secondary external clock
synchronization source (marked SYNC-SECOND). The expansion cage can house the
primary and/or secondary synchronization card in slot 4 and 5, respectively.
Figure
6-23 displays the jumper configuration for clock synchronization. For further
information, see page 10-15, Digital Trunk Synchronization .
The primary and secondary card slots may be housed in the same cage.
