DBSAP 
 
A prerequisite for expanding HiPath 3800 to a two-cabinet system is that the DBSAP (Driver Board for Synergy Access Platform) board is mounted on the backplane of the expansion cabinet.
DBSAP ensures that the expansion cabinet receives HDLC, PCM and clock signals from the basic cabinet. In addition, an ID signal is created which indicates the availability of an expansion cabinet to the CBSAP.

The cable (C39195-Z7611-A10) is used as the connection cable between basic cabinet (X201 jack) and expansion cabinet (DBSAP board). To ensure smooth operation, use only shielded cables with a maximum length of 1 m.
