User Manual

MBF, Multi Band Repeater

PRODUCT DESCRIPTION AND USER'S MANUAL

The Control Module contains a battery backed-up real time clock, which will stay active even during a power

failure. The real time clock is used for instance to keep track of when an alarm occurred, when to retransmit

an alarm and at what time of the day to send traffic report to the AEM.

If the repeater is controlled by the Axell 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.

4.2 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 unit and a number of remote nodes (repeaters)

connected to the OMU unit via fibre optic cables. 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.

4.2.1 Node Identification

All nodes have a unique address within the repeater system. This address is based on the serial number of the

node. When the system is installed to the Axell Element Manager, the 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 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.

4.2.2 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 from 0 to N where N is number of nodes

Reading a parameter from node 3 is entered as:

AVITEC AB> @3 GET ATD

AVITEC AB>
