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) managed by the
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.

The SARI (Secondary ARI) is a secondary ARI number that enhances the PARI. The SARI,
when it exists, is generated by the base station.
