En Alcatel 1664 SM is a powerful SDH/SONET multiservice transport platform designed to meet the high-capacity and performance requirements of core and regional networks. Positioned at the upper end of the Alcatel-Lucent 1600 Series, the 1664 SM delivers robust transport capabilities for both legacy TDM services and next-generation Ethernet and data traffic.
With support for STM-1/4/16/64 and SONET OC-3/12/48/192 rates, the 1664 SM provides scalable, carrier-grade optical transport across long-distance and high-traffic metro networks. Its non-blocking, high-throughput switching fabric enables flexible grooming and aggregation of both high- and low-order traffic, helping operators maximize bandwidth efficiency while maintaining service quality.
The platform supports a wide variety of interface modules including E1, T1, Fast Ethernet, Gigabit Ethernet, Fibre Channel, ESCON, and FICON, making it suitable for a diverse set of applications including mobile backhaul, ISP transit, enterprise access, and transport for mission-critical services.
Engineered for high availability, the 1664 SM includes comprehensive protection features such as SNCP, MSP, and ring-based restoration, along with SSM-compliant synchronization for precise network timing. Additionally, it integrates seamlessly with DWDM systems, enabling cost-effective expansion of capacity across existing optical infrastructure.
The system is fully manageable via the Alcatel-Lucent 1350 OMS, offering centralized configuration, performance monitoring, and fault management capabilities. At Carritech, we support the Alcatel 1664 SM with a full suite of lifecycle services, including hardware supply, repairs, technical support, and consultancy—ensuring reliable, long-term operation in demanding transport environments.

En Alcatel 1664 SM is a high-capacity SDH/SONET multiservice transport platform tailored for metro core and long-haul network environments. It supports a wide range of transmission rates including STM-1, STM-4, STM-16, and STM-64 (OC-3, OC-12, OC-48, and OC-192 equivalents), allowing for scalable deployment from access aggregation up to high-capacity backbone infrastructure. Its fully non-blocking cross-connect matrix enables dynamic switching of both high-order (VC-4/STS-1) and low-order (VC-12/VT) signals, ensuring efficient bandwidth utilization and traffic grooming.
The modular chassis supports a broad selection of interface cards, including legacy PDH (E1, T1, E3, DS3), high-speed optical interfaces, Fast Ethernet, Gigabit Ethernet, and storage-oriented ports such as Fibre Channel, FICON, and ESCON. The platform’s architecture supports hot-swappable modules, allowing for service expansion and maintenance without network disruption.
To enable Ethernet transport over SDH/SONET, the 1664 SM incorporates support for GFP (Generic Framing Procedure), VCAT (Virtual Concatenation), and LCAS (Link Capacity Adjustment Scheme). This allows carriers to deliver flexible and efficient Ethernet services using their existing optical infrastructure, while supporting advanced features such as VLAN tagging, Q-in-Q, and traffic policing.
The platform is designed with carrier-grade protection mechanisms, offering Multiplex Section Protection (MSP 1+1), Sub-Network Connection Protection (SNCP), and ring protection schemes for maximum service continuity. Synchronization is maintained through internal and external sources, with full support for Synchronization Status Messaging (SSM) to ensure accurate clock distribution across the network.
Power is supplied via redundant -48V DC feeds with per-card DC/DC conversion for fault isolation and resilience. The system is designed to fit into standard ETSI 19-inch or 23-inch racks and is cooled via passive or active systems depending on configuration. Centralized management is provided through the Alcatel-Lucent 1350 Optical Management Suite (OMS), offering SNMP, CLI, and GUI access for provisioning, fault monitoring, performance analysis, and remote upgrades.
