Alcatel-Lucent 1660SM P21E1

The Alcatel-Lucent 1660SM P21E1 is an essential interface card designed for the Alcatel-Lucent 1660 Synchronous Multiplexer (SM) platform. This module facilitates the aggregation and transport of lower-speed digital traffic within Synchronous Digital Hierarchy (SDH) or Synchronous Optical Networking (SONET) infrastructures. Specifically, the P21E1 card provides 21 E1 (2.048 Mbps) interfaces, enabling the connection of various legacy or access network equipment to the higher-capacity optical backbone. Typical use cases for the 1660SM P21E1 include extending the reach of existing SDH/SONET networks, interconnecting digital cross-connect systems (DCS), or providing voice and data services over traditional TDM (Time-Division Multiplexing) lines. Its robust design ensures reliable performance in demanding telecom environments, making it suitable for carrier-grade applications where stability and continuity are paramount. The card integrates seamlessly into the 1660SM chassis, supporting various network topologies. Revo Distribution Limited supplies this refurbished Alcatel-Lucent 1660SM P21E1 to support telecommunications providers and data centre operators in maintaining and expanding their existing infrastructure. By offering high-quality, tested refurbished parts, Revo enables significant cost savings while ensuring operational continuity for critical network systems that rely on proven SDH/SONET technology.
