Alcatel 90-2517-21 T1CE Telecom Interface Module

Alcatel 90-2517-21 T1CE Telecom Interface Module is an official Alcatel Lucent component designed to add a dedicated T1 telecom interface to the Newbridge MainStreet Xpress 36170 backbone switch (the BRIDGE MainStreet Xpress platform). In catalogs, the part is also listed as 90-2517-21/M, indicating a commonly referenced variant that preserves the same functionality. This T1CE module is intended for installation in the MainStreet Xpress 36170 chassis to provide a T1 interface within the MainStreet Xpress family, aligning with the platform’s network interface module lineage. The 36170 line, originally produced by Newbridge and later marketed under Alcatel-Lucent, is noted in vendor references as a backbone switch for ATMnet deployments, with the 36170 serving as a modular host for line-interface and interface cards. As such, the 90-2517-21 T1CE card plays a role in configuring T1/DS1 transport connections within the chassis, supporting carrier or enterprise configurations that require a T1 telecom interface in a modular environment. The component is recognized across multiple catalogs as a legitimate MainStreet Xpress 36170 T1CE option, ensuring compatibility with the platform’s backplane and neighboring modules within the 36170 family.
