Element Manager, the AEM will automatically time synchronize repeaters, to ensure that the time is always set
correctly in the entire repeater network. Slave repeaters are synchronized from the OMU.
3.2 Network Nodes
Note! The description in this section is based on a master-slave set-up of the system, where the OMU is the
node master and the repeaters are the slaves.
An Axell Wireless OMU-Repeater system consists of an OMU and a number of remote nodes (repeaters)
connected to the OMU unit via fibre. During software setup of the system, all nodes installed in the system are
configured in the Control Module. Hence, the node master contains a list of all the repeaters in the system. Once
a node is added to the system, it is also written to all the nodes installed. This means that all nodes in the
repeater system have information about all other nodes, allowing for a very good overview of the entire repeater
system no matter what node the repeater system login is made from.
3.2.1 Node Identification
All nodes have a unique address within the system. This address is based on the serial number of the node.
When the system is installed to the Axell Element Manager, the node master unit is assigned a unique repeater
ID within the AEM database.
This number is on the form:
XX-YY-ZZZZ
where
XX is the AEM installation number within the network
YY is the region number within the AEM-system
ZZZZ is the site installation number
Within the repeater system, all slave nodes (repeaters) are given a unique ID, based on the AEM assigned ID.
The nodes share the XX-YY- part of the master ID, but the ZZZZ is replaced by the node’s serial number.
Example:
If the node master’s ID is 17-42-4711 and the serial number for a node in the system is 23BJ. The node’s ID
will be 17-42-23BJ.
3.2.2 Node Addressing Modes
When logging in to the OMU-repeater system, it is possible to view information about any of the nodes in the
system, as long as they are added to the node list. All nodes can be addressed in four different ways, all starting
with the @-sign.
Numeric Addressing
Each node in the network gets a unique ID-number in the Node List as they are added to the system. Node 0 is
always the master node.
Addressing is on the format:
@K
K from 0 to N where N is number of nodes
Reading a parameter from node 3 is entered as:
AVITEC AB> @3 GET ATD
14
Serial Number Addressing
A node can be accessed using the serial number of the node.
