Common Corporate Numbering Plan
In the Common Corporate Numbering Plan each
addressable entity in the private network is identified
by a unique network identity.
A network identity consists of:
• a unique location code for each node
having 1-4 digits
• an internal directory number,
having 1-4 digits
3 different types of Common Corporate Numbering
Plan are possible:
1 LOC (LOcation Code based numbering plan)
Each node or group of nodes is identified by a
unique location code. One or more nodes can form
a logical group. The grouping of nodes is
independent of geographical or public boundaries.
The dialling format is: LOCxxxx
LOC........location code
xxxx........internal directory number
2 CNP (Co-ordinated Numbering Plan)
Each node is identified by a unique internal directory
number. This numbering plan is related to the fixed
or co-ordinated numbering plan for tie-line traffic
but:
- no prefixing is necessary
- complete dialled number is sent to the network
The dialling format is: yyxx
yy.......node identity
yyxx...internal directory number
3 Mixed numbering plan
Covering the nodes within a local segment by a CNP
and covering the whole network by LOC.
I.e.: Nodes within a local segment are covered by
CNP and one or more logical segments are covered
by one LOC.
