Alcatel-Lucent LKA6 SI-S1.1/4 S!:11 Control Unit Board

The Alcatel-Lucent 108680042013 LKA6 SI-S1.1/4 S!:11 is a control unit board designed for centralized system management and coordination of optical transport network elements in SDH/SONET and DWDM platform architectures. This module functions as the primary shelf controller, providing comprehensive element management, inter-module communication coordination, network synchronization distribution, and system orchestration capabilities. The LKA6 SI-S1.1/4 S!:11 board implements redundant control plane architecture with hitless switchover capabilities and automatic protection switching to maintain carrier-grade availability exceeding 99.999%. It features high-speed backplane interfaces for communication with line processing units, service interface boards, cross-connect modules, and power distribution systems within the transport shelf. The module supports complete element management functionality including configuration provisioning, performance monitoring, fault management, security administration, and software download operations through standardized TL1, SNMP v3, and CORBA-based interfaces compatible with Alcatel-Lucent's 1350 OMS and third-party network management systems. Integrated non-volatile memory stores shelf configuration parameters, software images, operational logs, and alarm history for system recovery and compliance auditing. The board provides precision timing distribution and synchronization signal generation for all shelf-resident modules, ensuring phase-aligned operation across the transport platform. Power is distributed via redundant −48 V DC feeds with integrated voltage regulation, current monitoring, and overcurrent protection. Environmental specifications comply with ETSI EN 300 019 Class 3.1 and NEBS GR-63 Level 3 standards, supporting continuous operation in controlled telecommunications facilities with ambient temperatures from 0 °C to +45 °C and relative humidity up to 95% non-condensing. The LKA6 SI-S1.1/4 S!:11 is validated for deployment in Alcatel-Lucent 1660/1670/1642 series transport platforms and ensures interoperability with ITU-T G.783, G.803, G.872, and G.805 standards for carrier-grade network element management and synchronization.
