6 Provisioning
A new POTSwap (model EVDO910PS) will require provisioning by the cellular carrier before it can be used.
Provisioning occurs ‘over the air’ and sets up the cellular radio in the POTSwap to operate on the carrier’s network.
The phone number of the cellular radio is installed during provisioning.
When negotiating a service agreement with a cellular carrier, the MEID (Mobile Equipment IDentifier) of the POTSwap
cellular radio will be required. This 14 character code can be found on the label on the top of the POTSwap
enclosure. It can also be obtained using the ‘IDENTIFY’ command from the terminal configuration menu. See
section 4 - Configuration.
Provisioning can be performed by dialing *228 from a connected telephone device or from the terminal configuration
menu by entering the ‘PROVISION’ command. A signal strength indication of 3 or 4 LED ‘bars’ is recommended.
When provisioning using the *228 dialing option, a dial tone must be present before dialing. During provisioning, the
cellular carrier will provide an audio message about the success or failure of the provisioning process.
When provisioning using the ‘PROVISION’ command from the terminal configuration menu, the procedure can be
monitored by observing the output to the terminal. “Provisioning failed” will be reported if the provisioning was not
successful. Following provisioning using the terminal configuration menu, enter the REBOOT command restart the unit.
