Note! For repeaters that are to be used as slaves in an OMU-Repeater system all report configurations are

done from the OMU.

5.7 Set Up Remote Communication

Note! If the repeater is fibre fed and is set up as a slave- this section is not relevant since the remote

communication is handled by the node master – in most cases an OMU.

The repeaters can be configured with a wireless modem, a PSTN modem or Ethernet for the remote

communication.

5.7.1 Communication via Modem

The Control Module is responsible for enabling the power to the modem, unlocking the SIM-card, using the

configured PIN-code and making sure the modem is logged in to the network correctly. Depending on

network configuration and modem usage, the modem might require different modem initialization strings to

work properly. This modem initialization string is set and verified during repeater setup.

5.7.1.1

Modem Initialization

After a power failure, or upon user request, the Control Module performs a full initialization of the modem.

This consists of three steps:

 If the SIM-card in the modem has the PIN code enabled, the Control Module unlocks the PIN code. In

case wrong PIN-code is configured, the Control Module will not try to unlock the SIM again until the

PIN-code is changed. This avoids the SIM card being locked by a Control Module repeatedly trying to

unlock the SIM with the wrong PIN code.

 Once the SIM is unlocked, the Control Module waits for the SIM to log in to the network. Depending on

signal quality and network configuration this might take a while. The Control Module will wait a

configurable number of seconds (default 50 seconds) for the modem to login to the network. In case no

network is found, a modem power cycle will be initiated.

When the modem is successfully logged in to the network, the Control Module configures the modem with

the modem initialization string as configured when setting up the remote configuration. The modem

initialization string is a network dependent string. The default string is suitable for most networks, but some

networks might require some tweaking of this string.
