En Alcatel 1655 AMU (Access Multiplexing Unit) is a high-capacity, modular SDH access platform designed to aggregate a wide range of voice and data services at the edge of the network. Engineered for flexibility and scalability, it supports multiple interface types—including E1, T1, Ethernet, and subrate signals—making it ideal for service providers, utilities, and transport operators looking to consolidate access traffic and extend the life of their SDH infrastructure.
With robust cross-connect capabilities and support for STM-1 and STM-4 uplinks, the 1655 AMU offers efficient traffic grooming and service delivery from remote sites to central transport nodes. Its compact design, combined with a modular slot-based architecture, allows for easy expansion and in-service upgrades as network demands evolve.
At Carritech, we provide full support for the Alcatel 1655 AMU, including spare part supply, repair services, and expert technical assistance. Our goal is to help network operators maximise the value of their legacy infrastructure while maintaining high service reliability. With years of experience and global stock availability, Carritech is your trusted partner for long-term Alcatel SDH network support.

En Alcatel 1655 AMU is a versatile SDH-based access multiplexer designed for STM-1 (155 Mbps) and STM-4 (622 Mbps) uplink capacities. It offers a flexible, modular platform capable of handling a variety of interface types including E1, T1, V.24, V.35, Ethernet (10/100Base-T), and asynchronous data. This makes it suitable for aggregating multiple services at the access layer, whether for corporate connectivity, mobile backhaul, or critical infrastructure networks.
The system includes a high-capacity digital cross-connect matrix, enabling efficient traffic grooming and distribution of low-speed inputs into high-speed SDH streams. It supports both point-to-point and ring configurations, with integrated protection options such as SNCP (Sub-Network Connection Protection) and APS (Automatic Protection Switching) to ensure service resilience and high availability.
Clock synchronisation is handled via internal or external sources, with support for Synchronisation Status Messaging (SSM) to maintain accurate network timing. The unit operates on a standard -48V DC power supply and is designed for ETSI-compliant racks, offering ease of installation and maintenance in standard telecom environments.
Network management is performed via the Alcatel 1350 Management Suite, which provides local and remote access for provisioning, performance monitoring, alarm handling, and software upgrades. The system supports SNMP and CLI interfaces, ensuring compatibility with a wide range of NMS platforms.
Built for long-term reliability, the Alcatel 1655 AMU is field-proven in telecom and utility networks worldwide, offering a cost-effective way to maintain and evolve legacy SDH infrastructure.
