10.42.18.1. Network-Wide PIN Usage 
Users in local OpenScape 4000/HiPath 4000 networks (i.e. confined
to one company building/location) are able to use the "network-wide
PIN" feature (AMO FEASU) similarly to the previous system-wide PIN function,
for manual PINs and chip cards. The following data and functions of a
user's "home" station are available and usable at "foreign" stations
in such a network:
- Individual classes-of-service for voice(COS1 / LCRCOS1)
- Internal traffic restrictions group no. (ITRGR)
- Dial plan group no. (DPLNGR)
- Mailbox LED display for voice/fax messages
The range of functions available for the network-wide PIN feature is somewhat
restricted, compared to the standard, internal PIN feature. The following
restrictions apply to PIN usage within the home node and in remote nodes
of a network with network-wide PIN functionality:
- Follow-me function not available for all authorizations of a user's home station
- DPLN and ITR groups: the group numbers of the user's home station are used to access the appropriate lists in the remote node
- No follow-me function for repertory keys and DSS keys of a user's home station
- No follow-me function for SNR (redial) destination stored in user's home station
- No follow-me function for callback in user's home station
- No follow-me function for individual speed dialing list in user's home station
- No follow-me function for central speed dialing list in user's home station
- No follow-me function for programmed timed reminder calls
- PIN/PCODE verification against PIN/PCODE tables not possible
In cases where the follow-me function is not possible for home station
data and home station memory, the data of the remote station will be
used.
The "network-wide PIN" feature is intended for use in local networks
(i.e. confined to one company building/location). In corporate networks
distributed over different sites/locations, some limitations must be
expected. The PIN types (COPIN settings) must be identically defined
in all nodes of the network. In networks with open numbering schemes,
users must use the node number of their home node when identifying themselves
in foreign nodes. The ITR, DPLN, SPD2 and SPDC groups must be set up
analogously in all nodes of the network. If the LCRCOS groups are not
set up identically in all nodes of a network, outgoing connections may
cause blocking of incoming calls to other nodes.
The network-wide PIN feature is intended to save having to set up
separate PINs for the same users in the different nodes of a corporate
network.
