Circuit Switched Data
The modem is sold without an airtime agreement. The user must arrange
connection of the modem to a network and have it enabled for data use. The
service provider will supply a Subscriber Identification Module (SIM), which
is inserted into the Intelimax and acts as a key to enable its use. Telstra is
strongly recommended in Australia due to greater coverage.
When setting up the account, the service provider may require some
information such as the make and model of the modem being used. They will
then set up an account and provide a phone number. This phone number is a
voice number. However, voice is not supported in the Intelimax and it is not
possible for the data logger to receive data calls (circuit switched data) with a
voice number.
A data number is required for circuit switched data and SMS transmissions to
the data logger. The service provider will need to know this information when
setting up the account and enabling the SIM card. Telstra will need to know
that you require a Data Terminating Number. Furthermore, ensure that Bearer
Code 2620 is activated on your account. Bearer code 2620 is Telstra’s code for
data service on NextG. This can be done through the Telstra Business Centre or
a suitable reseller of Telstra data services. Telstra Shop employees are not
trained in industrial modem use and cannot help you set up a Data Terminating
Number.
There are options that can be specified to reduce complexity and cost of the
service. You can remove all ancillary services such as Call Waiting, Call
Diversion and Message Bank as these are not required.
If the unit is set up with a security code or PIN number, it should be disabled
before use with the Campbell Scientific data logger. The security code or PIN
number can be disabled by putting the SIM card into a normal digital mobile
phone and select the security menu. Exact key presses will depend on the
mobile phone used, but from this menu it should be possible to disable the PIN.
If you experience difficulty getting Circuit Switched Data enabled for your
SIM card, contact Campbell Scientific Australia.
The sim card must not be removed while the unit is
powered up. This may result in damage to the modem
and/or sim card.
