Alcatel-Lucent 3JR20059BAAG02 eCEM-U channel element module for the 9926 BBU V2 baseband unit chassis. Tech-Star (UK-based, shipped worldwide) – enquire for stock.
The Alcatel-Lucent 3JR20059BAAG02 is an eCEM-U (enhanced Channel Element Module) card for the Alcatel-Lucent 9926 BBU V2 chassis, a compact baseband unit platform used in 2G/3G/4G-LTE radio access networks. The eCEM-U slots into the 9926 BBU alongside the eCCM-U controller card and provides baseband channel-element processing capacity for the base station, handling signal processing for the air-interface channels serviced by the shelf. It is designed as a field-replaceable, hot-pluggable module so operators and service engineers can add capacity or replace a faulty unit without taking the whole baseband unit out of service. The 9926 BBU family was widely deployed by mobile network operators during Alcatel-Lucent’s LTE rollout period and remains supported through the secondary/refurbished telecom parts market. This listing is for a genuine Alcatel-Lucent OEM part, sold as working stock. Tech-Star (UK-based, shipped worldwide) stocks this and related 9926 BBU spares – please get in touch to confirm current stock and compatibility with your shelf revision.
