Views

Cellular interface view

Predefined user roles

network-admin

mdc-admin

Parameters

timer time: Sets the response timer, in the range of 1 to 300, in seconds.

auto-recovery threshold: Specifies the consecutive response failure threshold for auto recovery. The value range for the threshold argument is 0 to 10. To disable auto recovery, set the value to 0.

Usage guidelines

A 3G/4G modem might malfunction in an unstable 3G/4G network or when the application environment changes. 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.

Views

Cellular interface view

Predefined user roles

network-admin

mdc-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

PIN will be changed to “4321”. Continue? [Y/N]:y

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.

To perform PIN verification, you also need to execute the pin verify command to save the PIN of the SIM/UIM card on the device. After the PIN is saved on the device, the PIN is used for verification automatically when required.

You might be required to provide the current PIN when you enable or disable PIN verification. This requirement depends on the 3G/4G modem model.

For some 3G/4G modems, you can disable PIN verification only when the 3G/4G modems pass PIN authentication.

Consecutive failures for enabling or disabling PIN verification lock a SIM/UIM card. To unlock the card, execute the pin unlock command.

Examples

# Enable PIN authentication.

mdc-admin

Parameters

at-string: Specifies a configuration directive string, a string of 1 to 300 characters. This argument can be an AT directive (containing +++, A/, or be any string beginning with AT) or a CNS directive. For more information about AT directives, see the sendat command in Layer 2—WAN Access Command Reference. Table 7 describes the CNS directive samples. The format of this argument depends on the device model.

Table 7 CNS directive d escription

Directive | Description
CNS n | Controls the CNS heartbeat debugging switch. · n = 00000500000000000000—Enables CNS heartbeat debugging. · n = 00000800000000000000—Disables CNS heartbeat debugging.

Usage guidelines

The sendat command does not verify the configuration directive. Each time it issues one configuration directive to the 3G/4G modem, lowercase characters are automatically converted to uppercase characters.

One sendat command issues one configuration directive. To issue multiple configuration directives to a modem, you must repeat the sendat command.

Configuration directives might cause malfunction of a 3G/4G modem. When you issue a configuration directive to the modem, make sure you understand the impact on the 3G/4G modem.
