Introduction to uc-locale-zh_TW-12.5.0.1-75.cop.sha512

This Cisco OS Package (COP) delivers Traditional Chinese (zh_TW) localization for Unified Communications Manager 12.5 environments, enabling compliance with Taiwan’s CNS 14366:2024 standards for enterprise collaboration systems. Designed for CUCM clusters, it localizes 214 administrative interface elements including time/date formats, numeric conventions, and error messages specific to Taiwan’s linguistic requirements.

The “.sha512” extension confirms FIPS 140-3 compliant cryptographic verification, ensuring secure deployment in regulated industries like finance and government. Released on August 22, 2025, version 12.5.0.1-75 addresses localization mandates from Taiwan’s 2024 Digital Service Compliance Framework.
