Introduction to ps-locale-ar_DZ-14.0.1.1001-1.cop.sha512

This cryptographic-secured localization package enables Algerian Arabic (ar_DZ) language support for Cisco Unified Communications Manager (CUCM) 14.x environments. Developed under Cisco’s North African Language Initiative 2025, it addresses linguistic requirements for enterprises operating in Algeria and Maghreb francophone regions, complying with ITU-T E.123 international notation standards.

The “sha512” suffix confirms NIST-compliant integrity verification through FIPS 180-4 standards. Released in Q1 2025 as part of the 14.0.1 maintenance cycle, this update implements Unicode 15.0 specifications for Arabic script rendering and bidirectional text alignment.
