Alcatel-Lucent 3EC16687AABB 01 AACU-C Control Unit Board

The Alcatel-Lucent 3EC16687AABB 01 AACU-C (Advanced Access Control Unit - Centralized) is a control unit board engineered for comprehensive broadband access network management, subscriber service orchestration, and multi-service access node (MSAN) control in telecommunications access network platforms. This module provides centralized control and coordination functions for digital subscriber line access multiplexers (DSLAM), fiber-to-the-x (FTTx) aggregation platforms, and copper/fiber hybrid access systems, delivering intelligent service provisioning, quality of service (QoS) enforcement, bandwidth management, and subscriber line coordination across metropolitan and regional broadband access deployments. The AACU-C card implements advanced control plane functionality including dynamic spectrum management (DSM), vectoring coordination for crosstalk cancellation, line bonding coordination, seamless rate adaptation (SRA), dynamic bandwidth allocation (DBA), and automated configuration management for optimized DSL and fiber access performance over varying loop conditions and network topologies. The board features high-speed backplane interfaces for communication with line interface modules (ADSL2+, VDSL2, G.fast, GPON, POTS, ISDN), uplink cards (Gigabit Ethernet, 10 Gigabit Ethernet, STM-1/OC-3), system control processors, timing distribution units, and power management systems for coordinated network operation. Advanced features include automated subscriber line testing and diagnostics with built-in test equipment (BITE) capabilities, remote loopback testing, performance monitoring of line parameters including attenuation, signal-to-noise ratio (SNR) margin, bit error rate (BER), CRC errors, and line profiling, traffic shaping and policing per ATM, Ethernet, and MPLS specifications, and comprehensive Quality of Service (QoS) enforcement with priority queuing, weighted fair queuing (WFQ), hierarchical QoS (H-QoS), class-based queuing (CBQ), and traffic prioritization for differentiated service delivery across voice, data, and video applications. The module supports integration with broadband remote access servers (BRAS), optical line terminals (OLT), aggregation routers, and service edge platforms through Ethernet, ATM, or IP uplinks with support for PPPoE, IPoE, 802.1Q VLAN tagging, Q-in-Q (802.1ad), MPLS, and IPv4/IPv6 dual-stack encapsulation for service multiplexing, traffic engineering, and next-generation network migration. Management interfaces include SNMP v3, TL1, TR-069, NETCONF/YANG, RESTful APIs, CORBA, and proprietary element management system protocols for integration with Alcatel-Lucent's 5520 AMS, 5620 SAM, 1350 OMS, and third-party network management systems, OSS/BSS platforms, and service orchestration frameworks, providing access to subscriber port configuration, service profile management, bandwidth allocation policies, performance statistics, alarm status, diagnostic information, and software image management. The AACU-C implements redundant controller architecture with automatic protection switching, stateful switchover, graceful restart capabilities, and distributed database synchronization to maintain carrier-grade availability exceeding 99.999% and zero service disruption during controller failover events. Power is distributed via redundant −48 V DC feeds with integrated voltage regulation, current monitoring, overcurrent protection, and intelligent power management. 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 AACU-C is validated for deployment in Alcatel-Lucent 7300/7330/7340/7360 ISAM FTTU/FTTN/FTTB platforms, 7450 ESS, 7750 SR service routers, and related broadband access and service aggregation systems, and ensures compliance with ITU-T G.992.1/G.992.3/G.992.5 (ADSL/ADSL2/ADSL2+), G.993.2 (VDSL2), G.9701 (G.fast), G.984/G.987/G.9807 (GPON/XG-PON/XGS-PON), G.993.5 (G.vector), ATM Forum specifications, IEEE 802.1Q/802.1ad/802.3/802.1p, IETF RFC 2516 (PPPoE), MEF specifications, DSL Forum/Broadband Forum TR-069/TR-101/TR-167/TR-301, and ETSI TS 101 388 standards for carrier-grade broadband access network control, multi-service delivery, and next-generation access network evolution.
