WAN CONFIGURATION
This menu only appears when the SIP-2 equipment has the optional wireless WAN
interface.
5.5.1
cell0 submenu
This submenu is used to configure the wireless interface data. The submenu has four
different sections, which are described below.
WAN:
•
Enable Wireless WAN.
This allows the WAN interface of the equipment to be
enabled and disabled by selecting ON and OFF, respectively.
Selecting
the
ON
option
will
make
the
equipment
try
a
new
GPRS/UMTS/HSDPA/LTE session, in accordance with the subscriber data (PIN,
APN, Authentication method, user, password). In the case of
dual SIM
functionality, the subscriber data will be those corresponding to the primary SIM.
The
OFF
option disables the WAN interface, and is the default option.
Consequently, you should enable this option if you want the GPRS/UMTS/LTE
service, after FIRST configuring the necessary parameters for establishing the
operator session.
•
Primary SIM
. In the case of
dual SIM
functionality, this permits users to determine
which of the two available SIMs will act as the primary one: SIMA or SIMB. In this
operating mode the SIM that is not selected is therefore the secondary or back-up
SIM. It is also possible to establish an operating mode with alternation of the SIMs
(
alternated
) each time the equipment is started up, as well as an operating mode
for random selection of the primary SIM each time the equipment is started up
(
random
).
•
Request DNS.
Tick this box and the equipment will request the addresses for DNS
servers if connected to the GPRS/UMTS/LTE service.
•
Maximum number of retries.
This gives the number of retries (3 to 10) that can be
made to try and establish the operator session. If the number of retries is used up,
the equipment will be rebooted.
In the case of
dual SIM
functionality, the number of retries is for each of the SIMs.
In this way, once the number of retries with the primary SIM has been used up, the
equipment will try to establish connection using the secondary SIM. If it is not
possible to connect with the secondary SIM, once the number of retries has been
used up, or if the secondary SIM is disabled, the equipment will be rebooted.
