4.4 SIM Card PIN protection

FIf a SIM card is PIN-protected and the PIN is not programmed in SmartGate UMTS, UMTS/GSM LED indicates the state and the PIN tone is transmitted on telephone line.

PIN Entering by PCManager

Like other parameters, the PIN code can be entered using a PC programming tool. The PIN will be entered automatically upon every 2N® SmartGate UMTS power up.

PIN Entering via Telephone Line

PIN entering via a telephone line connected to FXS interface:

  1. Hook off the phone, you can hear the PIN tone.
  2. Enter the PIN using the DTMF. You can cancel the wrong PIN by entering of a  , or you can hang up before sending a  .
  3. To confirm enter a  .
  4. If you hear the busy tone in a while (a few seconds), you have entered the PIN correctly. Hang up and wait for registering to the UMTS/GSM network.
  5. If you hear the PIN tone again in a while, you have entered a wrong PIN. Re-enter the PIN correctly.
  6. If you hear the PUK tone in a while, you have entered a wrong PIN and the SIM card is blocked. Use the mobile phone to unblock the SIM card.

PIN entering via a telephone line connected to FXO interface if 2N® SmartGate UMTS is used as gateway for extension line of PBX:

  1. Dial the SmartGate UMTS's extension number on your PBX. 2N® SmartGate UMTS detects ringing and after off hook generates the PIN tone.
  2. Enter the PIN using the DTMF. You can cancel the wrong PIN by entering a , or you can hang up before sending a .
  3. To confirm enter a  .
  4. If 2N® SmartGate UMTS after a while (a few seconds) hangs up, you have entered the PIN correctly.
  5. If you hear the PIN tone again in a while, you have entered a wrong PIN. Re-enter the PIN correctly.
  6. If you hear the PUK tone in a while, you have entered a wrong PIN and the SIM card is blocked. Use the mobile phone to unblock the SIM card.

A correctly entered PIN is stored in SmartGate UMTS's memory as if you had programmed it using the PCManager. The PIN will be entered automatically upon every 2N® SmartGate UMTS power up.

Automatic PIN Entering

You need not enter the PIN upon power up if it is stored in 2N® SmartGate UMTS – it is entered automatically. This function is useful in case of power failure; 2N® SmartGate UMTS is operable in a short time after power recovery without any intervention by the operating staff.

Caution!

  • One PIN entering option is exhausted by the attempt to enter the PIN automatically upon SIM card or PIN change. If wrong, the automatically entered PIN is cleared from the internal memory to avoid another false attempt upon next power on. There are still two manual PIN-entering attempts after such unsuccessful automatic entering. To prevent the unsuccessful automatic PIN entering, delete or program properly the 2N® SmartGate UMTS PIN using the PCManager in the case of SIM card change.
