This plugin supports the Telecom Discovery and Discrepancy Identification \& Reconciliation solutions by providing shared logic and system properties. These properties control the Telecom Discrepancy Identification \& Reconciliation log, also known as the TSOM CMDB Audit, which focuses on auditing telecom-related configuration items (CIs) and their relationships within the CMDB. Show full answer Show less ## Key Features * **System Properties:** Several configurable system properties govern the audit process, including logging levels, the types of relationships audited, threshold settings for discovery dates, and specific CI tables targeted by audits (such as equipment, interface cards, network interfaces, slots, and subslots). These properties allow customization of the audit scope and behavior to fit organizational needs. * **Telecom Discrepancy Audits:** * **Telecom Discrepancy Audit:** Examines relationship records in the `cmdbrelci` table to validate parent-child CI relationships based on latest discovery dates, CI models, and model relationships (if TNI Core is installed). It filters on equipment CIs discovered via TSOM sources. * **Telecom Logical Connections Discrepancy Audit:** Audits logical connections in `cmdbcinilogicalpath`, checking for empty endpoints and ensuring each endpoint connects to only one unique logical connection. * **Telecom Network Topology Discrepancy Audit:** Reviews network topology CIs in `cmdbcinetworktopology`, verifying the presence of necessary relationships such as Contains:Contained By with equipment and Members:Member Of with logical connections. ## Practical Use for ServiceNow Customers This capability enables customers managing telecom assets and networks to maintain accurate and consistent CMDB records by identifying discrepancies in discovered telecom data and relationships. It helps ensure data integrity by automatically auditing telecom equipment, interfaces, logical connections, and network topology CIs, and flags inconsistencies for reconciliation. By configuring system properties, customers can tailor the audit process to their specific environment and discovery sources. The detailed audits support proactive management of network data quality, reducing errors in service mapping, impact analysis, and operational processes dependent on up-to-date telecom CMDB data. The system properties are part of the TSOM Visibility plugin (sn_tsom_core) and control the Telecom Discrepancy Identification \& Reconciliation log (TSOM CMDB Audit). 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.

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.
