Administration of Spectralink IP-DECT
Base Stations
Note:
Not relevant to the Spectralink IP-DECT Server 200.
It is necessary to connect base stations to the system and configure synchronization ways for the
Spectralink IP-DECT Base Stations.
In a multi-cell DECT system, the base station radios must be synchronized to each other to achieve
the optimum handover experience, when handsets are moving around among the base stations.
The synchronization ways of the base station can be determined using one of the following methods:
l Radio based synchronization
Base stations that synchronize with each other via radio must be within radio coverage of each
other.
l LAN based synchronization (license required)
For more information about ordering and downloading a license, see "Ordering Licenses" on
page43 and "Loading Licenses" on page43.
Note:
Synchronization via LAN and radio can be combined in the same DECT installation.
Even when a base station is configured to synchronize via LAN, the base station trans-
mits the signal required for synchronization via radio. Therefore, base stations syn-
chronizing via radio can retrieve their synchronization signal from a base station
synchronizing via LAN.
If configured as Radio/LAN Gateway, an IP-DECT Base Station will use an over- the-air
synchronization as the source of synchronization and act as a LAN sync master. With this
type it is possible to add a LAN synchronized segment of IP-DECT Base Stations to an
existing synchronization chain of base stations.
To get an overview or in case of troubleshooting, it is possible to:
l check the synchronization state of the of the base station. For more information, see "Check-
ing Sync State of Spectralink IP-DECT Base Station" on page138.
l check for loops in the synchronization chain. For more information, see "Checking for Loops"
on page138.
