    Visit the ServiceNow Store website to view all the available apps and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the ServiceNow Store version history release notes.

    Dependencies and Requirements:
    • Telecom Visibility Core (sn_tsom_core)
    • Discovery Core plugin (com.snc.discovery.core), which is automatically installed by Discovery.
    • ITOM Discovery License plugin (com.snc.itom.discovery.license). You must activate this plugin.
    • ITOM Licensing plugin (com.snc.itom.license). For more information, see Request Discovery.
    Pattern execution logic: By default, when a TSOM pattern is run, it executes both the TSOM-specific and the corresponding ITOM pattern (e.g., Telco Router runs Router). This ensures shared ITOM libraries are reused when needed. To override this behavior:
    • Use the system property sn_tsom_patterns.itom_pattern_enabled.
    • Setting this property to false ensures only the TSOM-specific pattern is executed.

    Procedimento

    1. Install the Horizontal Discovery application.
      See Discovery setup, as it is foundational for running Telecommunications Discovery Patterns.
    2. Obtain and install Telecommunications Discovery Patterns:
      1. Install the Telecommunications Discovery Patterns (sn_tsom_patterns) from the ServiceNow® Store.
    3. Set up a MID Server and synchronization Patterns:
      1. Synchronization the installed patterns with the appropriate MID Servers to confirm they’re ready for use:
        1. Navigate to Discovery > MID Servers.
        2. Select Pattern Sync to Mid.
        Nota:
        This action synchronizes both TSOM and ITOM patterns.

        For more information on how to configure a MID Server, see Configuring MID Server.

    4. Configure TSOM System Properties:
      1. Set the system property sn_tsom_patterns.itom_pattern_enabled to define the logic for whether to use only the TSOM Pattern or a combination of ITOM and TSOM patterns.
        1. Navigate to All > System Properties > All Properties.
        2. Select sn_tsom_patterns.itom_pattern_enabled.
        3. Check that the Value is set to true (default).

        If you want TSOM to run only TSOM patterns and exclude ITOM patterns, set the Value to false.

        Nota:
        The default setting is configured to use both TSOM and ITOM patterns.
    5. Enable the replacement of various ITOM patterns with TSOM patters on a specific MID Server:

      For example: The Telecom Router pattern replaces the Network Router pattern for a specific MID Server when mid.telecom.discovery.patterns.enabled is set to true for that MID Server.

      1. Go to the Filter Navigator and type ecc_agent_config.list.
      2. Select mid.telecom.discovery.patterns.enabled (each MID Server has this parameter).
      3. Check that the Value is set to true.

      Repeat this configuration for each MID Server that you want to use for running TSOM patterns.
