Configure Synchronization to Another DECT System
An IPBS that is configured as a sync master can be configured to synchronize to another
DECT system. If the site contains multiple DECT systems disturbance between the systems
can be avoided if the systems are synchronized. Synchronization between the systems is
done by configure an alien RFPI in the sync master.
The synchronization using alien RFPI is done on a "best effort" basis. If the alien system is
powered down during operation of the IP-DECT system the IP-DECT system will still
continue to operate. Also if the alien system is not found during startup of the sync master
it will start to operate anyway. When configure an alien RFPI at least all carriers that are
enabled in the alien RFPI must be enabled in the IP-DECT system.
When configure an alien RFPI and an alternative alien RFPI this must be different RFPIs on
the same alien system, not different RFPIs on different alien DECT systems.
Note: If an alien RFPI is configured on an existing IP-DECT system it may take several hours
before the system is synchronized to the alien system.
Configure an alien RFPI in the air sync master:
1 In the air sync master IPBS, select DECT > Air Sync.
2 Enter the alien RFPI in the Alien RFPI text field.
3 Enter an alternative alien RFPI in the Alt. Alien RFPI text field (optional).
4 Click "OK".
Configure Air Sync Backup Master
An backup air sync master may be configured to take over the air sync master role in case
of failure or power down of the original air sync master. The backup master must be
placed close to the original sync master. The backup master will start to operate as a sync
master in case the sync master has not been heard within 5 minutes. As soon as the sync
master is heard again the backup master will start to operate as a sync slave.
Note: If the IP-DECT system is configured to synchronize to another DECT system this
synchronization will be lost during the time the original air sync master is not operating.
A backup master is normally not needed for short interruptions on the sync master
(restart, software upload, etc.).
Normally no RFPI needs to be configured when using an backup master but if it is
configured this must be the RFPI of the sync master.
Configure Air Sync Slave
Normally no configuration is needed for the air sync slaves.The air sync slaves can be
configured to synchronize to a specific IPBS (a specific sync RFPI) in the IP-DECT system.
This is normally not needed, but if a sync RFPI is configured care must be taken not to
create sync rings.
Configure RFPI in the air sync slaves (optional):
1 In the air sync slave, select DECT > Air Sync.
2 Enter the sync RFPI in the Sync RFPI text field.
3 Enter an alternative sync RFPI in the Alt. Sync RFPI text field (optional).
4 Click "OK".
