Alcatel-Lucent 3DB18126AEAB 01 P32E1DS1 Service Interface Board

The Alcatel-Lucent 3DB18126AEAB 01 P32E1DS1 is a high-density service interface board engineered for E1/DS1 service aggregation and transport in optical transport network platforms for SDH/SONET architectures. This module provides thirty-two independent E1 (2.048 Mbps) client interfaces for aggregating legacy TDM services, cellular backhaul traffic, PBX connectivity, and enterprise leased lines onto synchronous optical network infrastructure in metro access and aggregation applications. The P32E1DS1 (Port 32 E1/DS1) card features high-density 75Ω coaxial 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) mapping per ITU-T G.707 and G.704 specifications with support for structured and unstructured E1 modes, timeslot assignment, and channelized operation. Advanced features include automatic protection switching (APS) with sub-50ms switchover, loopback testing capabilities (local and remote) for service validation and fault isolation, performance monitoring of bit error rate (BER), code violations, eroded seconds, unavailable seconds, and frame alignment errors, and comprehensive alarm indication signal (AIS), remote defect indication (RDI), and loss of signal (LOS) detection and generation. The module supports integrated clock recovery, jitter attenuation per ITU-T G.823 specifications, and synchronization distribution for timing-critical applications. 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 1650SM/1660SM/1670/1696MS series transport platforms and ensures compliance with ITU-T G.703, G.704, G.707, G.783, G.823, G.826, G.828, and ETSI EN 300 417 standards for carrier-grade E1 service delivery and interoperability.
