Alcatel-Lucent 3AL89670AA AB02 Electrical Access 16xSTM1 Service Interface Board

The Alcatel-Lucent 3AL89670AA AB02 Electrical Access 16xSTM1 is a high-density service interface board engineered for STM-1/OC-3 electrical service aggregation and transport in optical transport network platforms for SDH/SONET architectures. This module provides sixteen independent STM-1/OC-3 electrical client interfaces operating at 155.52 Mbps for aggregating legacy TDM services, cellular backhaul traffic, and enterprise connectivity onto synchronous optical network infrastructure in metro access and aggregation applications. The Electrical Access 16xSTM1 card features high-density 75Ω BNC or 120Ω RJ-48 connectors for flexible integration with existing copper infrastructure in central office and remote node deployments. The board implements comprehensive SDH/SONET framing, pointer processing, and virtual container (VC-12/VC-3/VC-4) mapping per ITU-T G.707 and ANSI T1.105 specifications with support for concatenated and virtual concatenation (VCAT) modes. Advanced features include automatic protection switching (APS) with sub-50ms switchover, loopback testing capabilities for service validation and fault isolation, performance monitoring of bit error rate (BER), code violations, eroded seconds, and section/path overhead parameters, and Quality of Service (QoS) enforcement for TDM services. Integration with the transport shelf backplane provides connectivity to cross-connect matrices for flexible traffic grooming and bandwidth management across the transport network. Management interfaces include TL1, SNMP v3, and proprietary element management system protocols for integration with Alcatel-Lucent's 1350 OMS and third-party network management systems. Power is supplied via −48 V DC backplane distribution with hot-swappable design enabling field replacement without service disruption. 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 module is validated for deployment in Alcatel-Lucent 1696MS/1650SM/1660SM/1670 series transport platforms and ensures compliance with ITU-T G.703, G.783, G.826, G.828, and ANSI T1.105 standards for carrier-grade STM-1/OC-3 electrical interface service delivery.
