​​1. Introduction to ps-locale-cs_CZ-15.0.1.2000-1.cop.sha512​​

This SHA512-authenticated localization package provides native Czech (cs_CZ) language support for Cisco Unified Communications Manager (CUCM) 15.0.1 and associated collaboration systems. Designed for enterprises operating in Czech Republic and Central Europe, it implements ISO 639-2/B language standards across administrative interfaces, IP phone displays, and system alerts to comply with EU multilingual accessibility directives (2016/2102/EC).

Certified under Cisco’s Global Localization Program, the “.cop” extension confirms validation through Cisco’s Software Digital Signature initiative. The SHA512 cryptographic checksum ensures file integrity during distribution, meeting Czech National Security Office (NBÚ) cybersecurity requirements for government-grade deployments.
