Gateway / Cellular

The Settings > Cellular section shows the status of the embedded Cellular modem (in the case where this is present – this is an optional Gateway component).

Cellular Network Status

The following information is provided as part of the status of the Cellular Modem:

Status: Whether or not the modem hardware is detected / enabled.

Manufacturer: Modem manufacturer, as reported by the modem.

Model: Modem model, as reported by the modem.

Serial Number: Modem electronic serial number, as reported by the modem.

Version: The version of the modem installed, as reported by the modem.

Network: The network type supported by this modem.

Cellular Network Settings

The following information is used to configure the 3G cellular network connection:

Enable Cellular Modem: Whether or not to enable the cellular modem. This does not indicate whether or not the Gateway has successfully connected to the cellular network using the modem.

Modem Identifier: A text string which will identify this modem. This field is optional. The modem identifier is validated with the following set of acceptable characters: [A-Za-z0-9.!*^_-].

Dialstring: The dialstring to be used when the Gateway initiates the connection to the peer-to-peer network provided by the cellular modem. If this field is left empty, no dialstring will be used. The dialstring is validated with the following set of acceptable characters: [A-Za-z0-9.#*,&].

APN: The Access Point Name of the cellular provider’s data connection. This field is mandatory and may be obtained from the cellular provider. The username is validated with the following set of acceptable characters: [A-Za-z0-9.’ ‘_-].

Authentication: Type of authentication used by the cellular provider. A choice of ‘No Authentication’, ‘PAP’ or ‘CHAP’ is available. This field is mandatory and may be obtained from the cellular provider.

Username: If the authentication type is ‘PAP’ or ‘CHAP’, the username to use for authentication should be entered here. The username is validated with the following set of acceptable characters: [A-Za-z0-9._-].

Password: If the authentication type is ‘PAP’ or ‘CHAP’, the password to use for authentication should be entered here. The password is validated with the following set of acceptable characters: [A-Za-z0-9.!*^_-].

Enable Gateway as a Router: Currently this option is always enabled. When the modem is enabled, the Gateway acts as a router to bridge a device connected via the Ethernet interface onto the Internet.

When the modem settings are changed, a restart of the Gateway is required. In the case that the modem was disabled by the user, the Gateway will revert back to the factory default with a static IP address of 172.31.255.1 after restart. Thereafter, dynamic IP addressing or an alternative static IP address may be assigned using the Settings > Ethernet interface.

In the case where the modem was enabled by the user and connection to the cellular network was successful, after restart the Gateway will also be accessible via the Ethernet interface at 172.31.255.1. The Gateway will also be accessible via its external IP address (available on the Settings > Ethernet page) assuming this is permitted by the cellular operator.

Furthermore, a device with dynamic IP addressing enabled can be connected via Ethernet cable to the Gateway and it will be assigned an IP address in the range [172.31.255.50 to 172.31.255.149] by the Gateway, and will be connected to the Internet by the Gateway acting as a router.

In the case where the modem was enabled by the user, but connection to the cellular network was not successful, the Gateway will revert back to the factory default of a static IP address of 172.31.255.1 after restart. In this case the external IP address on the Settings > Ethernet page will be shown as “Unknown”.
