Alcatel-Lucent 3AL79088ACAA 01 1662 SMC SYNTH16 Control Unit Board

The Alcatel-Lucent 3AL79088ACAA 01 1662 SMC SYNTH16 is a control unit board with integrated synchronization functionality designed for centralized system management and precision timing distribution in the 1662 Synchronous Multiplexer - Compact (1662 SMC) platform for SDH/SONET network architectures. This module functions as the primary shelf controller and synchronization source, providing comprehensive element management, inter-module communication coordination, network synchronization distribution, and system orchestration capabilities optimized for compact metro transport deployments. The 1662 SMC SYNTH16 board implements redundant control plane architecture with automatic protection switching and hitless switchover capabilities to maintain carrier-grade availability exceeding 99.999%. It features high-speed backplane interfaces for communication with service interface boards, cross-connect modules, timing units, and power distribution systems within the compact 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 proprietary element management system interfaces compatible with Alcatel-Lucent's 1350 OMS. The SYNTH16 designation indicates advanced synchronization capabilities with support for 16 independent timing reference inputs, synchronous Ethernet (SyncE), ITU-T G.813/G.812/G.8262 compliant clock generation, and IEEE 1588v2 Precision Time Protocol (PTP) support for frequency and phase synchronization distribution. Integrated non-volatile memory stores shelf configuration parameters, software images, operational logs, and alarm history for system recovery and compliance auditing. 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 1662 SMC SYNTH16 is validated for deployment in Alcatel-Lucent 1662 SMC compact transport platforms and ensures compliance with ITU-T G.783, G.803, G.872, G.805, G.8261, and G.8264 standards for carrier-grade network element management and synchronization in metro access and aggregation networks.
