Dual-Cell status covers status of data synchronization. The status “Keep-alive” means normal operation, as well as
“Idle”.

DESCRIPTION
DUAL CELL
SYSTEM
Disabled
Enable this option to allow the Base unit to be set in dual-cell mode (can be
set either as master or slave in the dual-cell chain system – refer to MAC-
units in Chain section for details).
Valid Inputs: Enable, Disable
Must “save and reboot” after change from disabled to enable.
SYSTEM CHAIN ID
512
This is an identifier (in string format e.g. 2275) that is unique for a specific
dual-cell system.
The Chain ID value MUST not be equal to a used SIP account. The Chain ID
uses up a SIP account with this value.
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. Chain ID can be modified by provisioning only.
Note: There can be several dual-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.
DATA SYNC:
Multicast
To select between multicast or Peer to Peer data synchronization mode.
The multicast port range and IP addresses used is calculated from the chain
id.
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.
Using multicast this base IP is selected automatically.
The data sync feature uses the port range: 49200 – 49999
NOTE: Using Peer to Peer mode the IP of the base used for data sync. source
MUST be defined.
NOTE: Using Peer to Peer mode with version below V306 limits the system
automatic recovery feature – as there is no automatic recovery of the data
sync. source in Peer to Peer mode.
DUAL CELL
DEBUG
None
Enable this feature, if you want the system to catalogue low level dual-cell
debug information or traces.
Options:
Data Sync: Writes header information for all packets received and sent to be
used to debug any special issues. Generates LOTS of SysLog signaling and is
only recommended to enable shortly when debugging.
Auto Tree: Writes states and data related to the Auto Tree Configuration
feature.
Both: Both Data Sync and Auto Tree are enabled.
NOTE: Must only be used for debug purpose and not enabled on a normal
running system
