ISDN Interface

The DASS II interface and associated equipment allows the connection of Primary Rate
ISDN to the Digital Business System (DBS). A maximum of 30 digital channels can be
connected to any of the DBS systems irrespective of the system size. Connection of the
digital circuits will reduce the number of analogue lines which can be connected to the
system. The tables in the installation manual show which combinations are valid. The
maximum number of DASS channels plus analogue lines can never exceed 48.

Category 1 & 2 Calls
All calls on the ISDN have a Service Indication Code (SIC code) to allow the network to
determine the call type. The DBS will accept incoming calls with SIC codes 00H , 10H or 12H
only other call types will be refused. Outgoing calls from the DBS use the SIC 10H.
Direct Dial In
The network can send the last digits of the number dialled by the caller to the DBS. This
string can be 1 to 6 digits long dependant upon configuration and the network services being
subscribed to by the user. The DBS will use these digits to route the call to a specific
extension or group of extensions using a look up table.
