302 Matrix ETERNITY NE System Manual
The Mobile Port is configured to automatically locate and register with the Network that supports the
SIM Card installed on it. Also, at each power ON, the Mobile Port (i.e. SIM) will automatically register
with the Network that supports the SIM on it.
However, if the Mobile Port fails to register, it will restart the process of network registration on the
expiry of the Network Registration Retry Timer
68
. On the expiry of this timer, the system will retry
registration for the Count (i.e. number of times) configured and with each re-try attempt, the count will
be decremented by one.
• Select the Frequency Band supported by the service provider network whose SIM Card is installed in
the Mobile Port. Default: All Band.
• Frequency Band selection is not required, if the Mobile Port has SIMCOM 3G or Quectel 3G/4G
modules.
• When you change the Frequency Band, the change will be effected after the next system restart or the
next Mobile Port restart.
• Set the Network Selection Mode for the Mobile Port as Automatic or Manual. Default: Automatic.
At each power on, the Mobile Port will automatically locate and register with the Network that supports
the SIM Card present in it. If the Mobile port fails to register, it will restart the process of network
selection on the expiry of the Network Registration Retry Timer and will make as many attempts to
register as configured in the Network Registration Retry Count.
Enable the Manual Network Selection mode, when there is more than one network operator available
in the area
69
, so as to prevent the SIM Card from registering with another available network and
resulting in 'Roaming' charges.
• Select the Network Preferred Mode for the Mobile Port as Any (LTE/UMTS/GSM), GSM only, UMTS
only or LTE only. Default: Any (LTE/UMTS/GSM).
If you select the Network Preferred Mode as LTE only, calling functionality will be possible only if the
Service provider supports calling through VoLTE.
• If you have enabled Manual network selection mode, configure the table Priority for Manual Network
Selection.
In this table, enter the Network Operator Codes (MCC-MNC)
70
in the order of priority for the Mobile
Port. The codes must not exceed 8 digits. You can store up to 9 Network Operator Codes in the order
of priority.
So, whenever you register with the network manually, the system will select the Network Operator that
matches in order of priority. If the Mobile Port fails to register, it will restart the process of network
selection on the expiry of the Network Registration Retry Timer.
68. The Network Registration Retry Timer defines the time for which the Mobile port, which has failed to register with the network,
should wait before attempting to re-register with the network. Network registration retry timer is 2 minutes and is non-configurable.
69. This may be the case in border areas.
70. The Network Operator Code comprises of the Mobile Country Code (MCC) appended by the Mobile Network Code (MNC). The
MCC is usually a 3-digit code that identifies a country. A single country may be assigned more than one MCC. For example the
MCC assigned to India is 404, but same code applies to all network operators in the country.
The MNC is usually a 2/3-digit code. The MCC-MNC combination uniquely identifies the home network of the mobile terminal or
the mobile user. For example, AirTel, a GSM network operator in India, has different MNC assigned to its networks in various
states. The MNC for AirTel in the state of Maharashtra is 90, while the same for the state of Gujarat is 98.
