The Alcatel-Lucent 3HE00020ABAB01 7750 Service Router is a carrier-grade IP/MPLS routing platform engineered for high-performance packet forwarding, multi-service delivery, and network convergence in telecommunications service provider, enterprise, and data center environments. This modular router platform provides comprehensive Layer 2 and Layer 3 switching and routing capabilities with support for IP, MPLS, Ethernet, and carrier Ethernet services optimized for mobile backhaul, business services, data center interconnect, and Internet peering applications. The 7750 Service Router implements advanced routing functionality including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Intermediate System to Intermediate System (IS-IS), Routing Information Protocol (RIP), Multiprotocol Label Switching (MPLS), MPLS-Transport Profile (MPLS-TP), Virtual Private LAN Service (VPLS), Virtual Private Wire Service (VPWS), IP Virtual Private Network (IP-VPN), and Ethernet VPN (EVPN) for scalable service delivery across metropolitan, regional, and core network deployments. The platform features high-density 10/100/1000BASE-T Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, 40 Gigabit Ethernet, and 100 Gigabit Ethernet interface options with support for Optical Transport Network (OTN) interfaces for flexible connectivity to diverse network infrastructures. Advanced features include hierarchical quality of service (H-QoS) with multiple scheduling algorithms, traffic policing and shaping, congestion management, deep packet inspection (DPI), network address translation (NAT), firewall filtering, access control lists (ACLs), and comprehensive traffic engineering for optimized resource utilization and service differentiation. The router implements sophisticated operations, administration, and maintenance (OAM) capabilities including Bidirectional Forwarding Detection (BFD), Ethernet OAM (802.3ah/802.1ag/Y.1731), MPLS OAM, IP SLA, and performance monitoring for proactive fault detection and service level agreement (SLA) verification. Integration with Nokia's Network Services Platform (NSP), 5620 Service Aware Manager (SAM), and third-party network management systems provides centralized orchestration, automated service provisioning, performance monitoring, fault management, and software lifecycle management through NETCONF/YANG, RESTful APIs, SNMP v3, and TL1 interfaces. The 7750 Service Router supports redundant system architecture with hot-swappable routing engines, switching fabric modules, power supply units, and fan trays ensuring carrier-grade availability exceeding 99.999% and zero service disruption during component failover or maintenance events. The platform implements comprehensive security features including control plane policing, route filtering, prefix validation, Resource Public Key Infrastructure (RPKI), secure boot, hardware root of trust, and encryption for management plane communications. Power is distributed via redundant −48 V DC or AC 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 from 5% to 95% non-condensing. The 7750 Service Router is validated for deployment in service provider core, aggregation, and edge networks, enterprise data centers, and cloud infrastructure, and ensures compliance with IETF RFC specifications, IEEE 802.1/802.3 standards, ITU-T Y.1731/G.8031/G.8032, MEF specifications, MPLS Forum standards, and RoHS/WEEE directives for carrier-grade IP/MPLS routing and multi-service delivery.
