1. Introduction to uc-locale-nl_NL-15.0.0.1-17.cop.sha512

This Cisco Options Package (COP) provides native Dutch (Netherlands) localization for Cisco Unified Communications Manager 15.0.0.1 systems, designed to meet European Union language compliance standards (EU 2024/175). Released under Cisco’s Q2 2025 software maintenance cycle, it implements Dutch linguistic requirements including date/time formats (CET/CEST), numeric displays, and directory services with SHA512 cryptographic verification.

The configuration file follows Cisco’s secure COP deployment protocol requiring installation through Unified CM Administration Interface or Prime Collaboration Deployment 14.6+. Its dual-validation system combines digital signatures with SHA512 hashing to prevent unauthorized modifications, complying with Cisco’s 2025 Cybersecurity Compliance Framework.
