Alcatel-Lucent 3AG24176AAAA02 P4S16 Service Interface Board

The Alcatel-Lucent 3AG24176AAAA02 P4S16 is a service interface board designed for high-density STM-1/OC-3 service aggregation and transport in SDH/SONET optical transport network platforms. This module provides sixteen independent STM-1/OC-3 client interfaces operating at 155.52 Mbps for aggregating legacy TDM services, cellular backhaul traffic, and enterprise connectivity onto optical transport infrastructure. The P4S16 card features electrical or optical interface options with standardized connectors (BNC for electrical 75Ω/120Ω interfaces or LC/SC for optical single-mode/multi-mode fiber) to support flexible deployment scenarios in central office and remote node applications. The board implements comprehensive SDH/SONET framing, pointer processing, and overhead termination per ITU-T G.707 and ANSI T1.105 specifications with support for virtual container (VC-12/VC-3) mapping and concatenation. Advanced features include automatic protection switching (APS) with sub-50ms switchover, loopback testing capabilities for service validation, and performance monitoring of bit error rate (BER), code violations, and section/path overhead parameters. Integration with the transport shelf backplane provides connectivity to cross-connect matrices for flexible traffic grooming and bandwidth management. Management interfaces include TL1, SNMP v3, and proprietary element management system protocols for integration with Alcatel-Lucent's 1350 OMS. Power is supplied via −48 V DC backplane distribution with hot-swappable design. Environmental specifications comply with ETSI EN 300 019 and NEBS standards, supporting operation from 0 °C to +45 °C.
