Introduction to uc-locale-da_DK-15.0.0.1-16.cop.sha512

The ​​uc-locale-da_DK-15.0.0.1-16.cop.sha512​​ is a critical localization package for Cisco Unified Communications Manager (CUCM) 15.x environments requiring Danish (Denmark) language support. Developed under Cisco’s Software Maintenance Release (SMR) framework for Collaboration Platform 15.0, this cryptographic hash-verified component ensures compliance with Denmark’s telecommunication regulations, including ISO 8601 date formats (DD.MM.YYYY) and localized dial plan configurations for Scandinavian enterprise networks.

This package aligns with ISO 639-3 Danish (da_DK) standards and integrates with Cisco’s Collaboration Flex Plan 4.0 architecture. The “15.0.0.1” version designation guarantees compatibility with CUCM 15.0(1)SU deployments, while SHA512 validation provides FIPS 140-3 compliant file integrity verification.
