Lucent Technologies NS20N330BB 6-Port DS1 IMA Module

Lucent Technologies NS20N330BB 6-Port DS1 IMA Module is a dedicated telecom interface component that consolidates six DS1 ports into a single module, enabling multiple DS1 connections to be carried within a compact backplane or chassis. The device is listed as NS20N330BB and is accompanied by PSAX-1250 and 2300 designators, which help technicians verify part lineage and compatibility during installation or maintenance. In typical telecom and data-communications environments, a 6-Port DS1 IMA module provides expanded port density for DS1 traffic, allowing voice and data circuits to be routed through a shared infrastructure while preserving modularity and upgrade paths within compatible systems. When sourcing replacements or cross-referencing inventories, use the NS20N330BB designation along with the PSAX-1250 and 2300 identifiers to confirm exact part compatibility with your equipment.
