Introduction to uc-locale-ja_JP-12.5.0.1-54.cop.sha512

This SHA512-signed localization package provides comprehensive Japanese language support for Cisco Unified Communications Manager (CUCM) 12.5 deployments. Designed to streamline administrative workflows for Japanese-speaking IT teams, it translates 97% of system interfaces including configuration menus, diagnostic logs, and real-time monitoring dashboards.
