How to connect as a CSP/ISP Listener on UDAP

Follow these steps to prepare and validate your CSP/ISP Listener integration for the Emergency Vehicle Approaching use case. All PDF files can be found at the end of this article. 

✅ Preparation Steps

1. Request Participation

Send an email to I&W at info@talking-traffic.com with the request to connect to UDAP as a CSP or ISP. At least include the following information:

• Organization name

• Main contact person’s name

• Email address

• Phone number

What happens next:

• Based on your email, a Test Access request ticket is automatically created in Monotch’s ticketing system (see step 5).

• You will receive follow-up instructions from Monotch Service Support (typically via email/ticket).

2. Get Onboarded

• UDAP Support will onboard you and create your UDAP account.

What happens next:

• You receive instructions how to setup your UDAP account.

• Support confirms the test environment context and any prerequisites needed to start consuming data.

3. Understand the Interfaces

• Account & ID Management: TLEX Broker Admin Interface.pdf

• Session Orchestration & Data Consumption: TLEX Broker System Interface.pdf

What happens next:

• You understand how to:

  • manage accounts/IDs (Admin interface), and

  • orchestrate sessions + consume data (System interface),
    so you can implement the Listener correctly.

4. Understand the Payloads

• Specifications: Specification UDAP Early Warning Messages.pdf

• Examples: DENM Message Example.pdf

What happens next:

• You can implement message parsing/validation based on:

  • required fields and formats, and

  • example DENM payloads for testing.

5. Test Access

• After step 1, a ticket is automatically created in the Monotch Support Portal to setup your Test Access.

• What happens next:

  • Monotch Service Support provides what you need to start testing (depending on your setup), for example:

    • how to connect to the test environment,

    • which identifiers/permissions apply to your listener,

    • and any required access/configuration steps.

• When to use which support channel:

  • Before you’re integrated: respond via the Monotch Test Access ticket.

  • After you’re integrated: raise tickets in the UDAP Support Portal via https://udap-support.tlex.eu/en/support/login.

6. Develop Your Client

• Use TLEX Broker System Interface.pdf (and relevant interface guidance from step 3)

• Example implementations are available in multiple languages (Python, .NET, Java, etc.). This documentation can be found on the Monotch support Github page: Introduction - Subject Interface v1 

What happens next:

• You implement the CSP Listener client to:

  • establish a session,

  • consume messages from the relevant queue(s),

  • handle errors/retries and operational logging per the interface specs.

✅ Validation Steps

1. Internal Testing

• Create test client: TLC-Admin Interface.pdf

• Inject test data: TLC-System Interface.pdf
  (See ZIP folder in “Prepare” step)

What happens next:

• You can verify end-to-end behavior internally:

  • your client connects successfully,

  • test data is received and processed correctly,

  • your handling of message structure and edge cases is correct.

2. Complete Self-Assessment

• Use SAT: STD UDAP SAT for Early Warning EN base.pdf

What happens next:

• Complete the SAT and attach it together with supporting evidence (e.g., test logs, screenshots, or a short test report) to your support ticket.

• Monotch Service Support reviews your SAT + evidence and confirms approval or requests follow-up actions.

3. Wait for UDAP Support Validation

• UDAP Support will review and confirm your integration.

What happens next:

• UDAP Support will:

  • confirm whether your integration is approved, and/or

  • request changes if something is missing or not compliant, and

  • communicate the next step towards go-live (if applicable).
