Alcatel-Lucent 3AL81915ABAA 01 ISA-ES16 Service Interface Board

The Alcatel-Lucent 3AL81915ABAA 01 ISA-ES16 is a service interface board engineered for high-density Ethernet service aggregation and transport in optical transport network platforms for SDH/SONET and packet-optical architectures. This module provides sixteen independent Ethernet client interfaces for aggregating 10/100/1000BASE-T and Fast Ethernet services onto synchronous optical network infrastructure in metro access and aggregation applications. The ISA-ES16 card supports multiple Ethernet service types including 10BASE-T, 100BASE-TX, and 100BASE-FX interfaces with configurable port assignments, VLAN tagging, and dynamic bandwidth allocation optimized for carrier Ethernet service delivery. The board implements comprehensive Ethernet over SDH/SONET framing per ITU-T G.707, G.7041 (GFP), and G.7042 (VCAT/LCAS) specifications with support for virtual container (VC-12/VC-3/VC-4) mapping and Ethernet frame encapsulation. Advanced features include automatic protection switching (APS) with sub-50ms switchover, loopback testing capabilities for service validation and fault isolation, performance monitoring of frame loss, latency, jitter, and CRC errors, Quality of Service (QoS) enforcement with traffic prioritization, policing, and shaping per IEEE 802.1p/Q and MEF specifications, and Ethernet OAM (802.3ah/802.1ag/Y.1731) for service-level monitoring and fault management. 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 series transport platforms and ensures compliance with ITU-T G.783, G.826, G.828, MEF, and IEEE 802.3 standards for carrier-grade Ethernet service delivery.
