​​1. Introduction to cm-locale-zh_CN-15.0.1.2000-1.cop.sha512​​

This SHA512-validated software package provides ​​Simplified Chinese (zh_CN)​​ localization for Cisco Unified Communications Manager (CUCM) 15.0.1 and associated collaboration systems. Designed for enterprises operating in mainland China, it implements GB18030-2005 character encoding standards across administrative interfaces, IP phone displays, and system alerts to comply with China’s Cybersecurity Law and GB/T 2312-1980 technical regulations.

As part of Cisco’s Global Localization Program, the “.cop” extension confirms its certification as an authenticated Cisco Options Package. The SHA512 cryptographic signature guarantees file integrity during distribution, adhering to FIPS 180-4 standards. Compatible devices include Cisco 8800/9800 Series IP Phones and CUCM clusters running 15.0.1 base installations.
