Parameter
Default values
Description
Multi cell
system
Disabled
Enab
le this option to allow the Base unit to be set in multi
-
cell mode
(can be set either as master or slave in the multi-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
Empty
This is an identifier (in string format
e.g.
2275) that is unique for a
specific multi-cell system.
Note: There can be several multi-cell systems in EXP1240 network. Up
to 7 levels of base stations chains are permitted in a typical setup.
Please refer to accompanied document [2] for further details and
description.
Valid Input: 16 bit String length
Synchronization
time (s)
60 sec
This specifies the period in seconds when elements/nodes (
e.g.
Base
units) in a specific Multi-cell will synchronise 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.
Data Sync:
Multicast
To select between multicast or Peer to Peer data synchronisation
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.
Primary Data
Sync IP
Empty
IP of base station data sync source
–
the base handling the data
synchronisation.
Using multicast this base IP is selected automatically.
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.
Multi cel
l
debug
None
Enable this feature, if you want the system to catalogue low level multi
-
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
signalling 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
