Alcatel-Lucent 3JR20073 CAAC02 eCCM-U Module

The Alcatel-Lucent 3JR20073 CAAC02 eCCM-U module is the next-version Core Controller Module for the 9926 BBU V2 family, designed to fit in the existing 9326 D2U V2 rack layout without modification. As the eCCM-U, it provides OA&M management and transport control for the 9926 BBU V2 system, serving as the central controller that oversees operations and maintenance tasks. The part number is 3JR20073 CAAC02, and some listings reference a related variant named 3JR20073BB for 3G, described as factory-loaded with the option for later remote software upgrades to LTE. Vendor materials indicate that the 9926 D2U BBU can accommodate up to two eCCM-U modules, enabling flexible configurations and potential redundancy within the chassis. This module is specifically intended for use with the 9926 BBU V2 chassis, aligning with Alcatel-Lucent’s 9926 product line and the eCCM-U family of controller modules.
