System feature - Number conversion
Definition
The entries in the PNR contain 1-4 digit private directory
numbers being used to convert the dialled number to the
addressed CN node ( partial private number or to the
complete private number
Partial private number
If the private network access number covers only the
required node, the node can be reached, but the user
has to continue the dialling process in order to reach the
required extension.
In case of corporate calls via the public network, the
remaining part (= directory number) of the complete
number is sent out transparently without any further
conversion. This requires a relation between the private
numbering plan (=PNP) and public (ISDN) numbering
plans. The last digits of the PNP number and the partial
DDI number of the ISDN numbering plan have to be the
same, i.e. the same directory number.
The dialling format is: LOC xxxx -> PDN xxxx
LOC = network location code
(1 - 4-digit network location)
PDN = public destination number
(1 - 16-digit public network number)
xxxx = post dialled digits ( desired directory
number)
Example: ( see PNR table on page 12)
850 is programmed as a Private Access Number
corresponding to the LOCation code number. The user
dials a private network number 850 2xxx. The call will
be routed to the public network and must therefore be
converted into the corresponding public number
00 46 8 719 2xxx. The number conversion of the
LOCation code 850 into the subscriber number 00 46
8 719
is possible, but the postdialled directory number
is sent to the network without any translation or check by
the system. In both numbering plans, private and public,
the directory number part therefore must be the same
2xxx in order to reach the same destination.
Complete private number
If the private network access number covers the
complete private number, the called destination (end
extension) can be reached without suffix dialling.
There are however, restrictions:
• The complete private number must be a
1 - 4-digit internal directory number
• The complete public number conversion is
limited to 16 digits
The dialling format is: xxxx -> PDN
xxxx = complete private number
(1-4 digit private network number)
PDN = public destination number
(1-16 digit public network number)
Example: ( see PNR table on page 12)
3102 is a complete private network number and has
been programmed as Private Network Access
number. The user dials the private number 3102
which will be routed e.g. to the public network and
must therefore be converted into the corresponding
public number
18113102. A complete number translation is
possible and by this even the least significant digits
can be converted.
