2 Select a number between 1 and 292. If this is not done, the IPBS/IPBL will randomly
select a number.
NOTE: The number of system IDs will affect how many IPBSs/IPBLs that can be used
per PARI Master in an installation, as shown below:
System ID = 1 to 36: Max. 1023 IPBS / Pari Master
Max. 240 IPBL / Pari Master
System ID = 37 to 292: Max. 127 IPBS / Pari Master
Max. 127 IPBL / Pari Master
3 Click "OK".
4 Reset in order to make the changes take effect, see 8.22 Reset on page 138.
Note: The RFPI, which the PARI is a part of, can be used for localization of a handset
making a personal alarm. To ensure that RFPIs are system unique, use different System ID’s
for each PARI Master.
8.5.26 SARI
The SARI is the broadcast identity, which uniquely identifies an IP-DECT system. The SARI is
added in the PARI Master. It is possible to add more than one SARI (guest SARIs). This is
necessary if you want to join two separate IP-DECT systems and allow handsets to roam
into each other’s system. The advantage is that the handsets in the two different IP-DECT
systems need not be re-registered to a common SARI.
Note: Several guest SARIs have an impact on the system performance, so it is
recommended to use the same SARI across all PARI Masters in the system. If this is not
feasible, you can add up to 10 SARIs.
1 Select DECT > SARI.
Note: To access the SARI tab, the PARI function has to be enabled, see 8.5.15
Enable PARI Function on page 94.
2 Enter the SARI number in the SARI text field.
3 Click “OK”.
4 You can add optional guest SARI numbers in the empty field.
5 Click “OK”. All RFPs are reinitialized to broadcast also the added guest SARI.
8.5.27 Configure Air Synchronization
This section only applies to the IPBS.
IPBS System
The IPBSs use the DECT air interface to synchronize to each other. For an individual IPBS it
is not needed to configure which IPBS to synchronize to. It is needed to manually select
one or several IPBS as synchronization master candidate. The PARI Master assigns one of
these IPBS as an active sync master. The remaining candidates will act as sync slaves and
can be new sync masters in case the active sync master will fail/break. When using one
sync region it is recommended to configure at least two base stations in the middle of the
building as synchronization masters.
All IPBSs in sync slave mode sends its list over received sync candidates to the PARI Master.
The PARI Master informs the IPBS sync slaves which sync candidate it shall synchronize to.
