Telecom Discrepancy Audit

</td><td>

Audits records in the `cmdb_rel_ci` table. For each relationship record discovered by Nokia Altiplano or NSP, it validates the parent and child CIs based on: - Most recent discovery date - CI model - CI model relationship \(if TNI Core is installed\). **Note:** All discrepancy audits use a filtering mechanism that applies to equipment CIs. By default, the filter condition is: `discovery_source CONTAINS TSOM`.

</td></tr><tr><td>

Telecom Logical Connections Discrepancy Audit

</td><td>

Audits records in the `cmdb_ci_ni_logical_path` table. For each logical connection discovered by Nokia Altiplano or NSP, it checks: - Empty endpoint \(Port A or Port Z\) - Each endpoint must be connected to only one unique logical connection.

</td></tr><tr><td>

Telecom Network Topology Discrepancy Audit

</td><td>

Audits records in the `cmdb_ci_network_topology` table. For each network topology CI discovered by Nokia Altiplano or NSP, it verifies: - At least one Contains:Contained By relationship with equipment - At least one Members:Member Of relationship with a logical connection.
