  • 1 minute to read

    • Telecom Visibility provides foundational capabilities that support both Telecom Discovery and Telecom Discrepancy Identification & Reconciliation. It includes shared logic, enhanced CI class models, and Identification and Reconciliation Engine (IRE) updates tailored for telecom network elements.

    Before you begin

    Role required: admin

    Confirm that:

    • Your ServiceNow instance is licensed for TSOM.
    • Your MID Server is operational and validated for discovery.
    • You review any custom IRE rules applied to telecom CIs to help prevent overrides during upgrade.

    About this task

    To configure Telecom Visibility, you must install the required plugins and update the CMDB CI Class Models to version 1.69.0, which introduces telecom-specific IRE identification rules. This confirms accurate CI identification and reconciliation across telecom domains.
    Note:
    If you have customized IRE identification rules for any of the affected telecom CIs, upgrading to version 1.69.0 may override or impact those rules.
    The following capabilities are included with the Telecom Visibility subscription:
    Plugin Name Description Store App
    Service Graph Connectors sn_sgc_altiplano_connector Service Graph Connector for Nokia Altiplano Yes
    Telecommunications Discovery Patternssn_tsom_patterns Telecommunication Discovery Patterns Yes
    Telecom Visibility Plugin (Core logic)sn_tsom_core Core logic for Telecom Visibility and Discrepancy Reconciliation No
    Note:
    These plugins automatically trigger the installation or update of the CMDB CI Class Models application to version 1.69.0.

    Procedure

    1. Navigate to All > Plugins.
    2. Search for and install the following:
      1. Service Graph Connector for Nokia Altiplano ( sn_sgc_altiplano_connector)
      2. Telecommunication Discovery Patterns ( sn_tsom_patterns)
      3. Telecom Visibility (plugin) ( sn_tsom_core)

      3. Install or upgrade to version 1.69.0.
      Note:
      Installing any of the TSOM plugins listed above will automatically update or install version 1.69.0 of the CMDB CI Class Models app. If your instance doesn’t include TSOM plugins or you're on a pre-Yokohama release (for example, Washington DC or Xanadu), you can manually install or upgrade the store app.
    4. Navigate to CMDB > Identification Rules.
