​​Introduction to ps-locale-zh_CN-14.0.1.2000-1.cop.sha512​​

This locale package provides Simplified Chinese language support for Cisco Unified Communications Manager (CUCM) 14.0.1 systems, ensuring compliance with GB18030-2022 character encoding standards and Chinese telecommunications regulations. Designed for mainland China deployments, it enables proper rendering of Chinese characters on Cisco IP Phones (8800/7900 series), Webex Calling interfaces, and Unity Connection voicemail systems.

The SHA512 checksum file (*.sha512) implements FIPS 180-4 cryptographic verification to detect file tampering during distribution. Digitally signed through Cisco’s Secure Hash Validation Program (SHVP), this package meets ISO/IEC 19790-2 security standards for cryptographic modules.
