3.1 System Management
Allows the external caller to connect to an extension in the system directly. Assignable desti-
nations are: Operator, extension, or extension group. This requires a DDI number transmitted
from the ISDN network. The DDI number is converted to a specific extension number by using
a pre-programmed conversion table.
Explanation
1. An incoming call from the ISDN network reaches your DSHS (Digital Super Hybrid
System). The ISDN network informs DSHS of the DDI number.
2. DSHS converts the DDI number to an extension number and directs the call to the exten-
sion.
¥ You can store a DDI number (20 digits maximum) by System Programming.
¥ To reach an extension group, the group must have been previously stored by System
Programming.
¥ If a wrong number is entered, the call will be transferred to the operator.
¥ It is possible to use DND on a DDI call if the Class of Service permits.
