Alcatel-Lucent 3FE71254AAAA01 CFAS-B Control Unit Board

The Alcatel-Lucent 3FE71254AAAA01 CFAS-B (Control Function Access System - B) is a control unit board engineered for comprehensive broadband access network management, 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 CFAS-B card implements advanced control plane functionality including dynamic service activation, automated configuration management, bandwidth allocation coordination, traffic engineering, and policy enforcement for converged voice, data, and video services over copper and fiber access infrastructure. 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, and timing distribution units for coordinated network operation. Advanced features include automated subscriber line testing and diagnostics, remote loopback capabilities, performance monitoring of line parameters including attenuation, signal-to-noise ratio (SNR) margin, bit error rate (BER), and CRC errors, dynamic bandwidth allocation (DBA) for efficient upstream and downstream capacity utilization, 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), and class-based queuing (CBQ) for differentiated service delivery. The module supports integration with broadband remote access servers (BRAS), optical line terminals (OLT), and aggregation routers through Ethernet, ATM, or IP uplinks with support for PPPoE, IPoE, 802.1Q VLAN tagging, Q-in-Q (802.1ad), and MPLS encapsulation for service multiplexing and traffic engineering. Management interfaces include SNMP v3, TL1, TR-069, NETCONF/YANG, RESTful APIs, and proprietary element management system protocols for integration with Alcatel-Lucent's 5520 AMS, 5620 SAM, 1350 OMS, and third-party network management systems, providing access to subscriber port configuration, service profile management, bandwidth allocation, performance statistics, alarm status, and diagnostic information. The CFAS-B implements redundant controller architecture with automatic protection switching, stateful switchover, and graceful restart capabilities 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 CFAS-B is validated for deployment in Alcatel-Lucent 7300/7330/7340/7360 ISAM FTTU/FTTN/FTTB platforms 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 (GPON/XG-PON), ATM Forum specifications, IEEE 802.1Q/802.1ad/802.3, IETF RFC 2516 (PPPoE), MEF specifications, DSL Forum/Broadband Forum TR-069/TR-101/TR-167, and ETSI TS 101 388 standards for carrier-grade broadband access network control, service orchestration, and multi-service delivery.
