Alcatel-Lucent 3AL78832AA 1660 SM Access Module

The Alcatel-Lucent 3AL78832AA 1660 SM Access Module is an electrical access module for the 1660 SM metro service platform, designed to plug into the 1660 SM shelf and provide dedicated access interfaces. It is cataloged as 3AL78832AA within the 1660 SM Access Module family and is described in listings as supporting 21X2 Mbits across 120 OHM Port interfaces. This device is intended to deliver multiple 2-Mbit/s channels through a single, standardized port group, enabling multi-channel access within the 1660 SM network architecture. As part of the 1660 SM ecosystem, the module works alongside other cross-connect and backplane components to extend the system’s service access capabilities and port availability for SDH/SONET-based deployments. Verified details include the exact part number (3AL78832AA), the model family (1660 SM Access Module), the 21X2 Mbits capacity, and the 120 OHM port termination, which together define its core electrical access function within the 1660 SM node. The description focuses on these confirmed specifications and the module’s role in enabling scalable access within the 1660 SM platform, without extrapolating beyond the documented characteristics.
