Alcatel-Lucent 7705 SAR-W IP MPLS Service Aggregation Router 3HE07349AA

The Alcatel‑Lucent 7705 SAR‑W (Service Aggregation Router – WAN) is a compact, ruggedized routing platform designed for IP/MPLS service aggregation at the network edge. The 3HE07349AA is a specific hardware variant that includes a wide range of WAN interfaces and advanced timing capabilities. This router is purpose‑built for mobile backhaul, smart grid, industrial control, and enterprise WAN deployments where space, power, and environmental constraints are stringent.

Overview

The 7705 SAR‑W is part of the 7705 SAR family, which combines carrier‑grade routing with small form factor and low power consumption. It supports full IP/MPLS functionality, including MPLS‑TP, VPLS, VPWS, and L3VPN, as well as advanced OAM and performance monitoring. The platform is often deployed at cell sites, substations, or branch offices to aggregate traffic from multiple access nodes and backhaul it to the core network.

Key Features

• Compact 1U form factor with fanless operation (optional)

• WAN interfaces: T1/E1, DS3/E3, OC‑3/STM‑1, and Gigabit Ethernet

• MPLS‑TP, MPLS, and IP routing with full L2/L3 VPN support

• Integrated Synchronous Ethernet (SyncE) and IEEE 1588v2 PTP for precise timing

• Hardware‑based packet processing for high throughput

• Redundant power inputs (DC and AC options)

• Advanced QoS with H‑QoS and traffic shaping

• Management via CLI, SNMP, and Alcatel‑Lucent 5620 SAM

Technical Specifications

• Throughput: Up to 4 Gbps aggregate

• Ports: 4x GigE (copper/SFP), 2x T1/E1, 1x OC‑3/STM‑1 (optional)

• Memory: 2 GB DRAM, 512 MB flash

• Power Input: -48 VDC or 110/240 VAC (depending on PSU)

• Dimensions: 44.5 mm (H) × 441 mm (W) × 254 mm (D)

• Operating Temperature: -40°C to +65°C (hardened version)

• MTBF: > 200,000 hours

Applications

The 7705 SAR‑W is widely used in mobile backhaul networks to aggregate 3G/4G/5G cell site traffic over MPLS tunnels. It also serves as a WAN edge router for enterprise branch offices, connecting to MPLS/VPN services. In utility networks, it provides secure, time‑synchronized communication for substation automation and distribution management.

Compatibility

The router is interoperable with other Alcatel‑Lucent/Nokia 7750 and 7705 SAR platforms, as well as third‑party MPLS networks using standard protocols. It supports a wide range of optical and electrical SFPs for flexible media adaptation. Software releases are aligned with the 7705 SAR OS, ensuring consistent feature sets across the family.

Installation and Deployment

Installation can be wall‑mount, rack‑mount, or DIN‑rail mounted, making it suitable for constrained spaces. The router includes front‑access ports and LEDs for status monitoring. Deployment involves configuring interfaces, routing protocols, and MPLS tunnels via the CLI or zero‑touch provisioning using DHCP and Auto‑Install.

Conclusion

The Alcatel‑Lucent 7705 SAR‑W 3HE07349AA is a versatile, high‑performance aggregation router that brings carrier‑grade MPLS capabilities to the edge. Its compact size, wide temperature range, and advanced timing support make it a preferred choice for mobile backhaul, utility, and enterprise networks requiring reliable, secure, and synchronized IP connectivity.
