Incoming CN call
In case of incoming calls, the LPC has to be removed
and replaced by digits, available in the internal
directory number plan. The replacement is done by
using a programmed common abbreviated number
which must be equal to the LPC. The number
assigned to the common abbreviated number contains
the leading digits of the internal directory number
which will be combined with the remaining digits of the
incoming call.
Example: (same as above for outgoing calls )
virtual number plan of the PBX: 54000-54999
Internal directory number plan: 1000 - 1999
Abbreviated number: 54
with assigned number 1
Number presentation at RL0
Called CN number 54234
Abbreviated number 54
converts the leading digits
to a digit available in the internal
number plan 1
remaining digits of the dialled no. 234
Directory number 1234
Number presentation at RL1
Called CN number 87654234
LOC is detected and removed: 876
Abbreviated number 54
converts the leading digits
to a digit available in the internal
number plan 1
remaining digits of the dialled no. 234
Directory number 1234

Limitations
The implementation of the virtual numbering plan
relies on a composition of the internal 4 digit directory
number plan and the LPC, in order to simulate an up to
8 digit numbering plan for the CN.
The virtual numbering plan can be used for the internal
basic call handling (common abbreviated number
handles the number conversion also internally), but not
for the execution/programming of most of the internal
features, such as:
• Abbreviated number dialling common numbers
• Bypass Call diversion and follow me
• Call information logging
• Call metering
• Call pick up common
• Call pick up extension group
• DISA
• Diversion (direct/busy/on no reply)
• Display of the own virtual number
• Display of the called/calling virtual number
in case of internal calls
• Follow me
• Group (PBX) hunting
• Hotline
• Hotel guest room telephone
• Intercom
• Key system function
• Loudspeaker paging
• Mailbox system common
• Mailbox system individual
• Message system voice
• Message system call me
• Message system text
• Name selection
• Secretary function
• Supervision
• Telephone directory
