5. 6 Switch Groups
With the aid of the switch groups the routing configuration for the system can be con-
veniently adapted to the time and situation-related requirements of the customer. This
means for example that calls during the day can be routed differently to calls at night,
or differently at times with a high call volume to times with a low call volume (e.g. at ra-
dio stations or in telemarketing.
Certain destinations and functions are selected depending on the switching position of
a switch group. Each switch group has three switching positions. The switch positions
can be used for example for day, night and weekend. The switch groups have change-
over switches for
• Routing incoming calls to internal destinations in a CDE.
• Routing incoming calls to a welcome announcement of the announcement service
• Routing outgoing emergency calls
Switch group 1 also has changeover switches for
• allocating an external digit barring for each internal user
• Allocating an internal digit barring for each internal user
• Allocation of an internal destination for the door bell if another switch group is not
assigned to the control input of the option card.
