During a malfunction, the modem cannot respond to the device's requests or configuration commands. If the device does not receive any responses from the 3G/4G modem within the timer, a response failure occurs. When the number of consecutive response failures reaches the threshold, the device restarts the 3G/4G modem automatically. This releases the user from manually rebooting the modem.

The device does not restart the 3G/4G modem when the 3G/4G modem has not made a successful dialup since the last restart. This restriction avoids repeated restarts of the 3G/4G modem when there are configuration errors.

Examples

# Set the response timer to 20 seconds and the consecutive response failure threshold for auto recovery to 4.

<Sysname> system-view

[Sysname] controller cellular 2/4/0

[Sysname-Cellular2/4/0] modem response timer 20 auto-recovery 4

Predefined user roles

network-admin

Parameters

current-pin: Specifies the current PIN of the SIM/UIM card, a string of 4 to 8 digits.

new-pin: Specifies the new PIN, a string of 4 to 8 digits.

Usage guidelines

The new PIN is saved on the SIM/UIM card.

If PIN verification is enabled, execute the pin verify command to save the new PIN on the device after the PIN is modified.

Failure to modify the PIN in a maximum number of attempts locks the SIM/UIM card. The maximum number of attempts depend on the 3G/4G modem model. To unlock the card, execute the pin unlock command.

For some 3G/4G modems, you can modify their PINs only when the 3G/4G modems pass the PIN authentication.

Examples

# Modify the PIN of a SIM/UIM card.

<Sysname> system-view

[Sysname] controller cellular 2/4/0

[Sysname-Cellular2/4/0] pin modify 1234 4321

Parameters

puk: Specifies the PUK of the SIM/UIM card, a string of 4 to 8 digits. The PUK code of a SIM/UIM card is provided by the network service provider.

new-pin: Specifies the new PIN, a string of 4 to 8 digits.

Usage guidelines

A SIM/UIM card will be locked in the following circumstances:

·     Consecutive PIN modification failures.

·     Consecutive failures for enabling or disabling PIN authentication.

·     Consecutive PIN authentication failures.

If the SIM/UIM card is locked, the 3G modem cannot be used. To unlock the card, you can use the pin unlock command. The new PIN is saved on the SIM/UIM card.

If PIN verification is enabled, use the pin verify command to save the new PIN on the device after the SIM/UIM card is unlocked.

If you consecutively fail to unlock a card by using the PUK, the card will be locked permanently. To unlock a permanently locked card, contact the service provider of the card.

Examples

# Use the PUK to unlock a SIM/UIM card.

network-admin

Parameters

1xrtt: Specifies the 1xRTT mode.

evdo: Specifies the EVDO mode.

gsm: Specifies the GSM mode.

lte: Specifies the LTE mode.

low lowthreshold: Specifies the lower RSSI threshold value in the range of 0 to 150, which represents a lower RSSI threshold in the range of –150 dBm to 0 dBm.
