5. 5. 2 Routing Functions for Incoming Calls
Call distribution is allocated the following incoming routing functions:
• Routing a call to a destination, depending on the position of the allocated
switch group (see "Call destination", page 130).
• Routing a call to an alternative destination if the original destination is either
busy or if the call goes unanswered (see "Alternative Destinations", page 132).
• Restricting the number of calls incoming simultaneously on each call distribu-
tion element (Incoming connections setting) As soon as this limit is exceeded, any
subsequent caller will obtain busy, provided no alternative destination CDE if
busy has been defined.
• Routing a call to data service destinations:
Data service destinations can be configured for each call distribution element
(see "Data service", page 275).
• Routing a call to external remote control or modem:
This destination is normally allocated only once in every system to enable access
to external remote control via a DDI number. (See "Remote controlling features
from outside the system", page 537.)
