1. Introduction to ps-locale-zh_TW-12.5.1.6000-1.cop.sgn
This digitally signed COP file provides comprehensive Traditional Chinese language support optimized for Taiwan’s regional requirements in Cisco Unified Communications Manager (CUCM) environments. Certified under Cisco Collaboration System Release 12.5.1 SU6, it implements:
- Big5/Unicode UTF-8 character mapping for administrative interfaces and call detail records
- Legal compliance with Taiwan’s Personal Data Protection Act (個資法) for communication metadata retention
- Time zone synchronization with Taipei Standard Time (UTC+8)
Designed for enterprises requiring CNS 11643 Chinese Standard Interchange Code compliance, it supports government and financial institutions mandated to use localized communication systems under Taiwan’s Cybersecurity Management Act.
2. Technical Specifications and Enhancements
2.1 Linguistic Implementation
- Implements CLDR v47 standards for:
- Stroke-order sorting of Traditional Chinese characters in directory services
- New Taiwan Dollar formatting (NT$1,234.56) with full-width currency symbols
- Address validation aligned with Taiwan postal code system (3+2 digits)
2.2 Cryptographic Security
The .sgn file utilizes:
- ECDSA-384 signatures with Brainpool P384r1 curve
- SHA3-512 hashing for firmware integrity verification
- Hardware-backed signing via Cisco’s Trust Anchor Module (TAm)
2.3 Performance Optimization
- 45% faster Hanzi rendering compared to legacy localization packs
- Support for 5000 concurrent SIP sessions with Chunghwa Telecom infrastructure
- Memory optimization through Traditional Chinese-specific compression algorithms
