5.16.11.1. Feature Description 
A PIN code is required for certain voice numbers configured in the
LCR dial plan for public network access or for access to tie trunk circuits
for which a consultation call was selected for the first call or a call
forward was selected during execution. A typical application case is,
for example, on a campus, where users have to identify themselves via
PIN on generally accessible phones for the purposes of call charging.
This PIN code can be dialed after the external number has been dialed
(suffix dialing), or prior to that via the COPIN digit analysis result
(preselection). A PIN is never demanded in transit systems, and a PIN
code request is never sent in the originating system.
A distinction is made between three manifestations in the case of
the PINWM feature (PIN digit pattern):
Unchecked (PCODE) In this case, the PIN code comprises a defined number
of digits. In the existing PIN; this corresponds to the project code
PCODE. The behavior in the case of Unchecked, as well as its administration,
is likewise the same as for the PCODE.
Checked (PIN Mobile) In this case, the PIN code must agree exactly.
In the existing PIN, this corresponds to the PIN Mobile. The behavior
in the case of Checked, as well as its administration, is likewise the
same as for PIN Mobile.
Restricted (PIN Mobile with IDHome) Restricted corresponds to Checked,
but the "IDHome" feature is additionally set in the COPIN. This results
in the PIN code only being accepted at the base station.
The PINWM (PIN digit pattern) feature is based on the existing PIN
concepts (PIN mobile, PCODE,...) and likewise uses existing PIN procedures.
In order to setup PINWM, the STN personal identification numbers must
first be configured. A new type of PIN (COPIN) has been added. Whether
or not a number in the network is subject to the PINWM test is administrated
in the LCR digit pattern. For this digit pattern, an LDPLN entry then
has to exist with parameter PINWM=YES (Default = No). If an incorrect
PIN is entered when the PIN is requested, the LCR is triggered.
IMPORTANT:
During administration, it must be noted that the
PINWM is only of relevance for the first outgoing connection, and that
a check of the PINWM in a transit system no longer takes place. Numbers
which are administrated as closed numbering cannot be subject to the
PINWM.
