Entering the Number of a PISN Subscriber in Full
A complete PISN subscriber number unequivocally identifies a subscriber at
another PINX or a virtual subscriber.
Each unequivocal number of a PISN subscriber can be allocated a name in the sub-
scriber configuration. This enables:
• these subscribers to be dialled by entering the name rather than the call
number (dialling by name)
• the name of a virtual PISN subscriber to be displayed (CNIP)
Entering Wildcards for a PISN Subscriber Group
A number with wildcards identifies a PISN subscriber group (Fig. 2.3, PINX 1). They
can be:
• Internal subscribers of one or more PINXs
• PISN subscribers of another region
The wildcard is entered as an upper case "X" (e.g. 21X).
This method of entering PISN subscribers helps to reduce the number of entries
made. Moreover, not all the changes made to the internal subscribers of a PINX
need to be updated in the other PINXs. However, neither the call numbers nor the
names of the individual subscribers in the group are stored in a phone book (it is
not possible to retrieve the number from a phone book nor is dialling by name
possible, except if the number and name are also stored locally in a private phone
book).
Tip:
It is advisable to enter PISN subscribers first with wildcards in an initial
stage so that the numbering plan is quickly and transparently available
throughout the PISN, and is also already operational.
All the PISN subscribers to be available with dialling by name can then
be entered individually at a later stage.
Entering a Regional Prefix
If an individual or group entry belongs to another PISN region, the entry for the
PISN subscriber must be preceded by the regional prefix.
