The TSOM Visibility plugin enables the TSOM Visibility applications. It contains logic shared across the Telecom Discovery and Telecom Discrepancy Identification \& Reconciliation solution. {#system-properties-affecting-telecom-discrepancy-identification-reconciliation__table_c1p_wmd_b2c__entry__3} | Property Name | Recommended / Default Value | Description | |-|-|-| | sn_tsom_core.audit.log.level | Telecom Discrepancy Audits' Logging. | debug,info,warn Default value: info | | sn_tsom_core.audit.relationship_types | Displayed Names of Relationship Types that will be handled by Telecom Discrepancy Audit. | Comma separated list of relationship types names Default value: Contains::Contained by | | sn_tsom_core.audit.discovered_date.diff.threshold.in.days | Most recent discovered date threshold in days.

Telecom Discrepancy Identification \& Reconciliation System Properties (Impacts CMDB Audit)] {#system-properties-affecting-telecom-discrepancy-identification-reconciliation__table_c1p_wmd_b2c} {#system-properties-affecting-telecom-discrepancy-identification-reconciliation__table_ydx_rcb_yfc__entry__2} | Audit Name | Description | |-|-| | Telecom Discrepancy Audit | 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`. | | Telecom Logical Connections Discrepancy Audit | 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. | | Telecom Network Topology Discrepancy Audit | 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. | [Table 2.
