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 Coral IPx 500 main cage and the
additional two slots are pre-wired in each of the IPx 500 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 cage is shipped from the
manufacturer with the primary and secondary synchronization cards assembled in
slots 4 and 5 of the main cage. The expansion cage can house the primary and/or
secondary synchronization card in slot 4 and 5, respectively.
Figure 6-32 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.
