4.2.1.1  CDMA Provisioning

CDMA provisioning is different from GSM since CDMA (in most cases) does not use a SIM card.

The CDMA modem provisioning process creates a CDMA data connection to the mobile carrier network. This authenticates the modem and retrieves account information which is written to flash memory on the modem module itself, not the Digi’s configuration file. As the mobile account information is stored on the CDMA module, performing a factory reset on the unit will not remove provisioning information from the CDMA module.

Important points:

•The modem must be provisioned on the network before it will communicate.

•The modem must be in coverage area of the native carrier. It cannot be roaming.

•There must be sufficient signal strength available to provision the modem.

•Always use MIP Profile 1 for manual provisioning unless specified otherwise by your carrier or Digi Technical Support.

4.2.1.2  Automatic vs. Manual Provisioning

There are two types of CDMA provisioning: Automatic and Manual. This varies between carriers and even within carriers. Settings in the Web Interface vary based on carrier plan. Below are examples for Verizon Wireless and Sprint:

Verizon Wireless always uses Automatic. This means that no further settings are required in the Web Interface - simply press Start in the Automatic section and leave the fields blank.

Sprint has two types of plans, Vision for standard Internet connections and DataLink for private IP plans:

1.Sprint Vision uses Automatic provisioning. There are three fields of information that may need to be populated in the Automatic screen. Check with Sprint for correct values (if required).

2.Sprint DataLink requires Manual provisioning. The required fields in the Web Interface vary based on plan and type of embedded modem. As noted above, always use MIP Profile 1 unless otherwise specified by your carrier or Digi Technical Support.

Check with your carrier for information about the type of provisioning required and what, if any, data is required to be entered.

For more information on configuring the unit, please refer to the Digi TransPort User Guide which is available at www.digi.com.

4.2.2  Cellular: GSM

To configure the Wireless WAN/mobile interface on non-CDMA routers (GPRS/UMTS/HSPA), please refer to the Application Guide “QN02 - Configure the wireless WAN (PPP) interface” which can be found on the Digi Support site (http://www.digi.com/support/).

It is also essential to configure a dead link detection mechanism for routers using a Wireless WAN/mobile interface (such as GPRS/HSDPA/CDMA). Please refer to the Application Guide “AN07 - Wireless - Wide Area Network (W-WAN) Problem Detection and Recovery” which can also be found on the Digi Support site (http://www.digi.com/support/).
