User Manual

MBF, Multi Band Repeater

PRODUCT DESCRIPTION AND USER'S MANUAL

4.9.3 User Access in a Network Application

An operator can login to the system from any node in the network and access all parameters in all nodes,

including those in the node master unit. This can be done using a serial cable connected to the node’s LMT-

port or by remote access over the modem (GSM or PSTN) in the master unit, or in the repeater itself.

In an OMU-repeater system with slave-type repeaters the OMU unit polls the connected repeaters / nodes

regularly and keeps control of login requests. If a user at a repeater site wants to log in to the repeater system,

the OMU Control Module is responsible for granting / denying the login request. If a user forgets to log out

from the node when a session is finished, the system will automatically log the user out after a configurable

number of minutes of inactivity.

All nodes contain a copy of all user accounts (username and password). These are updated as soon as there is

a change or at system start-up.

All configuration and changes of this information needs to be made when the node has connection with a

master. A node in standalone mode cannot change the username or password.

4.10 Integration into AEM

When the repeater has been installed at site and the remote communication has been enabled, either through

the repeater’s own modem or via an OMU, the repeater can be integrated to the Axell Element Manager. This

is done by the operator of the AEM. After entering the telephone number to the repeater, the AEM dials up

the repeater, downloads all the repeater parameters and statuses into a database. When all parameters have

been downloaded, the AEM configures the repeater with the telephone number where alarms and reports

should be sent, and optionally with a secondary telephone number where the repeater can dial in case

connection to primary number fails.

When heartbeat reports and alarms are sent from the repeater to the AEM also the latest information about the

status and RF-configuration is included. This means that the AEM operator always has information about the

current status in the AEM database (and do not need to call the repeater to find this out).

Note! Once the repeater is integrated to the AEM, all changes to the repeater should preferably be done from

the Axell Element Manager in order to ensure that the database always contains correct information.

4.11 Upgrading Firmware

The software installed in the repeater is called firmware. Using the RMC it is possible to see what firmware is

installed, install upgrades etc.

The firmware can be upgraded in the field while the repeater is operational.

The RMC is used to upload software to the Control Module. Since the Control Module contains two separate

software banks, software can be downloaded to one bank while executing from the other. Once software is

successfully uploaded, the new software is executed.

All repeater configurations remain unchanged when upgrading the software to a new version.

The Control Module contains two different program banks. The software can be executed from one bank

while new software is downloaded to the other. When new software has been completely downloaded, the

execution is moved over to the new program bank. The software download can be done at site, or remotely

via a modem.

Note! During software download no measurements will be made in the repeater. However, the RF

transmission will still be fully operational.
