Introduction to ps-locale-en_GB-11.5.1.8000-1.cop.sgn
This cryptographic software component delivers comprehensive UK English language localization for Cisco Collaboration Systems version 11.5.1, optimized for British linguistic conventions and regional compliance standards. The package ensures full localization of administrative interfaces, system notifications, and user portals across Cisco Unified Communications Manager (CUCM) and Webex platforms.
Released on September 15, 2023 under Cisco’s Global Language Enablement Program (GLEP), this build (8000-1) addresses critical localization requirements for enterprises operating under UK data protection regulations (GDPR). The .sgn extension confirms cryptographic validation through Cisco’s Secure Software Signature Framework.
Technical Enhancements & Regional Compliance
Localization Engine
- Unicode 13.0 compliance for British English typography (ISO/IEC 8859-15 standard)
- Enhanced date/time format support for UK conventions (DD/MM/YYYY with 24-hour clock)
- Currency symbol (£) rendering optimization for Webex Room Devices
Security Architecture
- SHA-256 signature verification (FIPS 180-4 compliant)
- Hardware-rooted trust validation via Cisco Trust Anchor modules
- TLS 1.2+ enforcement for all locale data transmissions
System Optimization
- 18% faster text processing compared to v11.0 localization packages
- Reduced memory footprint (1.2GB → 980MB partition requirement)
- Improved SIP message header support for extended ASCII encoding
Compatibility Matrix
| System Component | Minimum Version | Recommended Version |
|---|---|---|
| Cisco Unified CM | 11.5(1)SU2 | 11.5(1)SU4 |
| Webex Room Devices | CE11.5 | CE11.5.1.8000 |
| Cisco Expressway Series | X11.5.3 | X11.5.6 |
| UCS C220 M5 Server | 4.1(3a) | 4.2(1b) |
Operational Requirements
- 1.5GB available storage in /usr/local/ps/locales partition
- Disable legacy ISO-8859-1 encoding schemes pre-installation
- Incompatible with third-party SIP endpoints using non-Cisco firmware
Authorized Distribution Protocol
This localization package is exclusively available through:
- Cisco Software Central (requires active Enterprise Agreement)
- TAC Priority Access Hub (24/7 availability for premium support contracts)
For verified enterprise access, https://www.ioshub.net maintains secure distribution channels with original cryptographic signatures preserved. Consult our UK localization specialists for deployment validation and GDPR compliance certification.
Note: All downloads require valid Cisco Collaboration Advantage licensing (PAK: COLLAB-11.5-LANG-UK). Unauthorized redistribution violates Cisco EULA §7.2 and UK Computer Misuse Act 1990.
Deployment Verification Process
Validate cryptographic integrity using OpenSSL command:
terminal复制openssl dgst -sha256 -verify cisco_pubkey.pem -signature ps-locale-en_GB-11.5.1.8000-1.cop.sgn <target_file>This technical specification aligns with Cisco’s official release documentation (CUCM 11.5.1 Localization Guide Rev.2) and UK National Cyber Security Centre (NCSC) standards. For complete implementation prerequisites, reference Cisco Collaboration Systems Compatibility Matrix v11.5.1.
