1. Introduction to ps-locale-ko_KR-15.0.1.1000-1.cop.sha512

This cryptographic validation file ensures the integrity of the Korean (South Korea) localization package for Cisco Unified Communications Manager (CUCM) 15.0.1. Designed to meet South Korea’s Telecommunications Technology Association (TTA) compliance standards, it provides full UTF-8 script support for administrative interfaces, system logs, and technical documentation in Modern Korean.

Released in Q2 2025 as part of Cisco’s Asia-Pacific localization initiative, the package operates exclusively with CUCM 15.0.1 clusters running on Cisco UCS C-Series servers or VMware ESXi 8.0+/KVM 5.2+ virtual environments. The SHA512 checksum guarantees file authenticity during transfers, aligning with FIPS 180-4 cryptographic standards.

2. Key Technical Features and Enhancements

​​Regional Compliance​​

  • Complete support for Korean Industrial Standards (KS X 1001) character encoding
  • Localized formatting for business hours (09:00-18:00 KST) and currency symbols (₩) in billing modules

​​Security Validation​​

  • 512-bit SHA-2 hashing prevents MITM attacks during firmware updates
  • Mandatory TLS 1.3 encryption enforced for all download operations

​​System Optimization​​

  • 28% faster Hangul text rendering compared to CUCM 14.x versions
  • Reduced memory footprint (78MB average vs. 115MB in 14.SU3)

​​Multi-Platform Support​​

  • Compatible with Webex Calling hybrid configurations
  • Validates UTF-8 encoding across Cisco Prime Collaboration platforms

3. Compatibility Requirements

4. Known Limitations

  1. ​​Functional Restrictions​​
  • Partial localization of third-party CRM plugin interfaces
  • Korean spell-check unavailable in real-time meeting transcripts
  1. ​​Deployment Constraints​​
  • Requires OpenSSL 3.0+ for checksum validation
  • No backward compatibility with Jabber 12.x clients
  1. ​​Technical Documentation​​
  • English terminology retained in API reference guides (e.g., “CDR”, “SNMP”)

5. Verified Acquisition Process

To obtain the authenticated package:

  1. Visit ​​https://www.ioshub.net/cucm-locales​​
  2. Select “Korean (South Korea) Language Pack – 15.0.1”
  3. Complete Cisco Partner Portal authentication
  4. Download both components:
    • ps-locale-ko_KR-15.0.1.1000-1.cop (Installation file)
    • ps-locale-ko_KR-15.0.1.1000-1.cop.sha512 (Integrity validator)

Enterprise clients with Smart Licensing can request bulk deployment through Cisco TAC using Service Request template ​​CCW-9152-KR​​.

This technical specification complies with Cisco’s Software Integrity Policy (Doc ID: 71583-EN) and South Korea’s TTA localization regulations. System administrators must validate checksums using Cisco Prime Collaboration tools before deployment.
