Direct Dialling Plan (Ddi Plan) - ASCOM Ascotel 2025 System Manual

Several Direct Dialling Plans per PBX / PINX
Several direct dialling plans are available. This ensures that the same subscriber
can be reached from the outside via different network accesses and that the cor-
rect CLIP is also transmitted in outgoing traffic.

Tip:
Use a separate direct dialling plan for each individual network access to
the public network (e.g. for different network providers, point-to-point /
point-to-multipoint connections, different SLGs or different direct dial-
ling ranges).
Direct Dialling Plans in the Private Leased-line Network
Direct dialling plans can also be used in the private leased-line network. This is the
case in particular if incoming calls from the private leased-line network are to be
routed depending on the switching position (see Page 2.216).
Linking a Direct Dial Number with a Call Distribution Element
Direct dial numbers are created as blocks with 1 to several numbers. When the
number range is created each direct dial number is automatically linked with a call
distribution element. A call distribution element can also be subsequently allo-
cated to several numbers.
