Alcatel-Lucent 3AL89540AAAA03 P16S1-4 Service Interface Board

The Alcatel-Lucent 3AL89540AAAA03 P16S1-4 is a service interface board engineered for high-density STM-1/OC-3 service aggregation and transport in optical transport network platforms for SDH/SONET architectures. This module provides flexible client interface capabilities for aggregating multiple STM-1/OC-3 signals operating at 155.52 Mbps onto synchronous optical network infrastructure in metro access and aggregation applications. The P16S1-4 card supports multiple STM-1/OC-3 optical or electrical interfaces with configurable port assignments, automatic protection switching, and dynamic bandwidth allocation optimized for legacy TDM service delivery, cellular backhaul connectivity, and enterprise leased line applications. 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.783, G.826, G.828, and ANSI T1.105 standards for carrier-grade STM-1/OC-3 service delivery.
