Configuring APN Settings on CPE Devices

You can configure Access Point Name (APN) settings on the following devices, with or without SIM change. You can change the APN settings either to use a private APN with the current LTE service provider or to use a different LTE service provider.

Note:

You can only insert a SIM card in the SIM1 slot of the LTE Mini-Physical Interface Module (Mini-PIM).

Following is the list of devices on which you can configure APN settings:

  • NFX Series—NFX150 and NFX250 CPE devices

  • SRX Series—SRX320, SRX340, and SRX345 CPE devices

Configuring APN Settings with SIM Change on CPE Devices

To configure APN settings with SIM change:

  1. Log in to Administration Portal.
  2. Select Resources > Templates > Device Templates.

    The Device Templates page appears.

  3. Select a device template and click Edit Device Template > Stage-2 Initial Configuration.

    The Stage-2 Initial Configuration page appears.

  4. Click APN Configuration tab and change the APN settings according to the guidelines provided in Table 1.
  5. Click OK.

    The new settings are applied after one minute.

  6. Remove the USB dongle from the CPE device, change the SIM card, and re-insert the USB dongle.

    The system checks for the new APN settings every minute.

    • If the applied APN setting is compatible with the new SIM card—The LTE WAN link and its tunnels goes down after one minute and remain down till the new SIM card is inserted. The LTE dongle LED indicates that the connection is down during this period. Maximum one minute after the new SIM is inserted, the LTE dongle LED indicates connection Up. The LTE WAN link and its tunnels comes up automatically.

    • If the applied APN setting is not compatible with the new SIM—The LTE WAN link and its tunnels goes down after one minute and remains down even after the new SIM card is inserted. The LTE dongle LED indicates that the connection is down even after the new SIM is inserted.

  7. To revert back to the old SIM, remove the USB dongle, replace the current SIM with the previous SIM, and re-insert the dongle.

    The system checks for the new APN settings every minute. Maximum one minute after the old SIM is inserted, the LTE dongle LED indicates that the connection is up (using the old SIM and old APN). The LTE WAN link and its tunnels comes up automatically
