Newbridge 90-2183-02/C Dual Receiver Card (CD 2.1) for the MainStreet Xpress 36170 ATM/DACS switching platform.
The Newbridge 90-2183-02/C is a Dual Receiver Card (CD 2.1) for the Newbridge MainStreet Xpress 36170 multiservice switching platform, a legacy ATM and DACS access and aggregation system later supported under Alcatel following Alcatel’s acquisition of Newbridge Networks in 2000. The MainStreet 36170 platform combined ATM switching with traditional TDM/DACS cross-connect functions in a single chassis, and receiver cards such as this one handled incoming signal reception for the shelf’s switching fabric, working alongside the platform’s control and switching cards. As a dual-channel card, the 90-2183-02/C provided receive-path capacity within the 36170 shelf, supporting the platform’s carrier-grade operation. The ‘/C’ suffix denotes a specific hardware revision level of this card, consistent with Newbridge’s part-numbering convention for the 36170 range. These cards remain in demand for maintaining legacy 36170 deployments still in service and for spares holding on decommissioned systems. Tech-Star (UK-based, shipped worldwide) supplies Newbridge and Alcatel-Newbridge 36170 spares including the 90-2183-02/C. Get in touch to confirm revision compatibility with your shelf.
