Overview

This node integrates with the Summa API to manage LTE subscription data, specifically allowing users to set the LTE ODB (Operator Determined Barring) profile for a given subscriber. This operation is useful in telecommunications scenarios where controlling call barring or service restrictions on LTE subscriptions is required.

Typical use cases include:

  • Updating subscriber profiles to enable or disable certain call barring features.
  • Automating subscriber management workflows in telecom backend systems.
  • Integrating with external systems that trigger changes in LTE subscription settings based on business logic.

For example, a telecom operator could use this node to programmatically update the ODB profile of a subscriber identified by their IMSI (International Mobile Subscriber Identity), enabling or disabling specific barring services as part of customer service automation.

Properties

Name Meaning
Imsi The International Mobile Subscriber Identity, a unique identifier for the LTE subscriber whose ODB profile is to be set. This is a required string input.
Odb The Operator Determined Barring profile value to assign to the subscriber. This is a required string input representing the desired barring configuration.

Output

The node outputs JSON data reflecting the result of the Set LTE ODB Profile operation. The exact structure depends on the Summa API response but typically includes confirmation of the update, status codes, and any relevant metadata about the subscriber or operation outcome.

If the node supports binary data output, it would represent related binary payloads from the API, but based on the provided code and context, the primary output is JSON-formatted response data.

Dependencies

  • Requires an active connection to the Summa API via an API key credential configured in n8n.
  • The node uses an HTTP client internally to communicate with the Summa backend.
  • Proper credentials must be configured and tested before execution.
  • No additional environment variables are explicitly required beyond the API authentication setup.

Troubleshooting

  • Common Issues:

    • Invalid or missing IMSI or ODB values will cause the operation to fail.
    • Authentication errors if the API key credential is incorrect or expired.
    • Network connectivity issues preventing communication with the Summa API.
    • API rate limits or permission restrictions from the Summa backend.

  • Error Messages:

    • Authentication failures typically indicate invalid credentials; verify and reconfigure the API key.
    • Validation errors on input parameters suggest checking the IMSI and ODB values for correctness and completeness.
    • Timeout or network errors require checking internet connectivity and API endpoint availability.

Resolving these usually involves verifying input parameters, ensuring valid credentials, and confirming network access to the Summa API.
