Introduction to ps-locale-pt_BR-14.0.1.1000-1.cop.sha512

This cryptographic localization package provides full Brazilian Portuguese language support for Cisco Unified Communications Manager (CUCM) 14.x systems. Officially released under Cisco’s Q2 2025 Software Maintenance Window (SWMW-UC-2025-05), it implements ISO 8859-15 character encoding for Brazil-specific diacritics and integrates ANATEL regulatory compliance templates for telecom systems deployed in Portuguese-speaking regions.

As a COP (Cisco Options Package) file with SHA-512 checksum verification, it requires 1.4GB disk space and supports CUCM clusters running base software 14.0.1.10000-1 or later. The package aligns with Brazil’s GDPR-equivalent LGPD data protection standards for call logging systems.
