Alcatel-Lucent 90-6704-02-00-H ATM/IP Multi-Rate Service Interface Board

The Alcatel-Lucent 90-6704-02-00-H ATM/IP Multi-Rate is a versatile service interface board engineered for multi-service aggregation and transport of ATM (Asynchronous Transfer Mode) and IP (Internet Protocol) traffic over SDH/SONET optical infrastructure in telecommunications network platforms. This module provides comprehensive multi-rate interface functionality supporting OC-3c/OC-12c and STM-1/STM-4 synchronous digital hierarchy rates for flexible service delivery in metropolitan and regional network deployments. The ATM/IP Multi-Rate card implements advanced service adaptation functionality including ATM cell processing, IP packet encapsulation, multi-protocol encapsulation over ATM (MPOA), classical IP over ATM (IPOA), and LAN emulation (LANE) for converged voice, data, and video service transport. The board features multiple optical interface ports supporting both intermediate reach (IR) and short reach (SR) configurations with standardized optical connectors (LC/SC) for connectivity to diverse network infrastructure. Advanced features include ATM traffic management with available bit rate (ABR), unspecified bit rate (UBR), constant bit rate (CBR), and variable bit rate (VBR) service categories, IP quality of service (QoS) enforcement with differentiated services (DiffServ) and integrated services (IntServ) support, comprehensive performance monitoring of ATM cell loss ratio (CLR), cell transfer delay (CTD), cell delay variation (CDV), and IP packet loss, latency, and jitter measurements. The module supports integrated ATM inverse multiplexing (IMA) per ATM Forum AF-IMA 01.00 specification for bandwidth aggregation across multiple lower-rate links, virtual path (VP) and virtual channel (VC) switching and cross-connection, and sophisticated traffic shaping and policing mechanisms. Integration with the transport shelf backplane provides connectivity to cross-connect matrices, timing distribution units, system control processors, and protection switching modules for coordinated network operation and automatic protection switching (APS) with sub-50ms switchover. Management interfaces include TL1, SNMP v3, NETCONF/YANG, ATM forum ILMI (Interim Local Management Interface), and proprietary element management system protocols for integration with Alcatel-Lucent's 1350 OMS, 5520 AMS, and third-party network management systems, providing access to ATM/VC configuration, IP addressing, QoS parameters, performance statistics, alarm status, and diagnostic information. The ATM/IP Multi-Rate implements redundant protection architectures including 1+1 optical line protection, multiplex section protection (MSP), VP/VC-level protection switching, and IP route redundancy with automatic revertive and non-revertive modes. Power is distributed via −48 V DC backplane with integrated voltage regulation, current monitoring, and overcurrent protection. 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 ATM/IP Multi-Rate is validated for deployment in Alcatel-Lucent 1650SM/1660SM/1670/1696MS series optical transport platforms and ensures compliance with ITU-T G.703, G.707, G.783, G.825, G.826, G.828, G.957, ATM Forum specifications (UNI 4.0, PNNI 1.0, ILMI 4.0, IMA 1.0), IETF RFC 1483/1577/2684, ANSI T1.105, Telcordia GR-253/GR-487, and ETSI EN 300 417 standards for carrier-grade ATM/IP multi-service interface functionality and converged network transport.
