Installing Printed Circuit Cards
8BSI CARD
The 8BSI(Base Station Interface) card must be inserted in slots 1,2 or 3 of same cabinet. If multiple 8BSI
cards are installed in an iDCS 500 L system then the 8BSI cards must be installed in the same cabinet.
Push firmly in the middle of the card to ensure that it is fully inserted into the back plane connector.
The Samsung iDCS 500 system receives it clock information from ISDN services connected so a PRI or
BRI card, where installed, must be installed in a lower slot number (e.g. C1-S1) than the 8BSI card.
However if ISDN circuits are not installed, the 8BSI card would normally be installed in slot 1 of the
iDCS 500 cabinet. The PRI supports ISDN PRI service. Push firmly in the middle of both card
ejectors on each card to ensure that it is fully inserted into the back plane connector. ISDN cards like
PRI and BRI use the external clock from the public network. So, when a SAMSUNG DECT system
use PRI or BRI, the system must align with the external clock as a slave. Also installed 8BSI card uses
the same clock as ISDN cards. So, the SAMSUNG DECT system determined the clock priority
according to the card type and the position of slot. At first, according to the second clock priority
and the 8BSI card has the lowest priority. In the next priority.
