SYSTEM CHAIN ID Empty This is an identifier (in string format e.g. 2275) that is unique for a specific
multi-cell system.
The Chain ID value MUST NOT be equal to a used SIP account.
NOTE: Chain ID is used as SIP account for check Sync. Default value is 512,
which means extension 512 must not be used – unless the chain ID is
modified. When there is a Multi-cell system up and running, the Chain ID
can be modified by provisioning only.
Note: There can be several multi-cell systems in SME network. Up to 24
levels of Base stations chains are permitted in a setup.
Valid Input: The Web site allow max 5 digits in this field.
SYNCHRONIZATION
TIME (S)
60 sec This specifies the period in seconds when elements/nodes (e.g. Base units)
in a specific Multi-cell will synchronize to each other.
If no keep-alive packets are received within a period of
2*NETWORK_SYNC_TIME, the base will be indicated as lost in the multi
cell configuration. The parameter is also used with “Auto create multi
primary” feature from the next section DECT system settings.
DATA SYNC: Multicast Select between “Multicast” or “Peer to Peer” data synchronization mode.
The multicast port range and IP addresses used is calculated from the
chain id.
NOTE: Please note that if there are over 150 base stations in a multicell,
the “Multicast” data sync should be used
The multicast feature uses the port range: 49200 – 49999
The multicast feature IP range: 224.1.0.0 – 225.1.0.0
Multicast uses UDP.
For multi-cast operation make sure that Multicast/IGMP is enabled on
your switch(es), else use Peer-to-peer mode.
PRIMARY DATA
SYNC IP
Empty IP of Base station data sync source – the base handling the data
synchronization.
