Model DCP-NextG Digital Cell Phone Kit

3 Getting Connected – Circuit Switched Data

The NextG 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 SAM3G+ and acts as a key

to enable its use.

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

SAM3G+, 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.

Note: Some users may have experienced reliability problems when calling a NextG modem

on the Telstra network from a non-Telstra telephone line. Please see Section 7, on

Troubleshooting for more information.
