1.5.3 PARI/SARI management (mobile access rights)
The ARI (Access Right Identity) is a 31-bit sequence, unique for each DECT network. ARI is
used for access rights management for all DECT terminals using the network via the base
stations.
The PARI (Primary ARI) is an ARI number assigned to a user. It consists of 3 elements:
• ARC. Access Right Class. Radio communication standard used by the PBX (e.g. B class
multi-cellular PBX).
• EIC, Equipment Installation Code: distributor reference (example: Aastra France) managed
by ETSI.
• FPN + FPS. Fixed Part Number and Fixed Part Sub-number. Network user reference (Aastra
customer) or PBX reference (see below), managed by Aastra.
The PARI is transmitted to the mobiles in encoded format by the base station.
Figure 1-3: PARI/SARI management
The SARI (Secondary ARI) is a secondary ARI number that enhances the PARI. The SARI,
when it exists, is generated by the base station.
The PARK (Portable Access Right Key) is the number associated with a PARI or SARI registered
in the cordless handset during initial identification on the DECT network. To avoid locking onto a
base station on which it is not authorised, the mobile possesses the PARK{y} information item,
containing the first y significant bits of the ARI (PARI or SARI) used to encode the right of access.
This information is loaded onto a cordless handset at the time of its registration.
FOR A SINGLE-SITE PBX MANAGING LESS THAN 32 CELLS:
A single PARI assigned to all the base stations is provided by Aastra. Authorisation access is
performed by testing the PARK registered in the cordless handsets which must correspond to the
PARI.
FOR A MULTI-SITE PBX WITH GLOBAL ACCESS (each mobile has access to the entire
multi-site network):
Each PBX has the same PARI(s). Multi-site base station access is by a common SARI. Access
authorisation is performed by testing the PARK registered in the cordless handsets. The PARK
must correspond to the SARI.
FOR OTHER MULTI-SITE CONFIGURATIONS:
Please contact Aastra (ask for the "pre-sales" engineer).
