Huawei 30298641 BTS3012 embedded power and signal cabinet, GM51 subrack family Telecom System Card / Module

The GM51DCTB (material code 30298641) is a backplane board for the Huawei BTS3012 base station’s embedded power and signal cabinet, part of the same GM51 subrack family as the confirmed GM51DCCU and GM51DCSU connection units. Like the related GM51DCMB backplane, its role is to physically interconnect the GM51-family cards within the cabinet, carrying power and signal buses rather than performing active processing. The distinct ‘DCTB’ designation suggests a different physical position within the cabinet to the ‘DCMB’ backplane (likely top-subrack versus main-subrack, consistent with the DCSU/DCCU slot-5/slot-6 split documented for this family), though the exact sub-position is not independently confirmed beyond its designation as a GM51-family backplane. Operators maintaining legacy BTS3012 GSM sites keep backplane boards like this as spares, since a backplane fault can take an entire subrack out of service. Tech-Star (UK-based, shipped worldwide) supplies this as a tested spare. Get in touch with our team to confirm compatibility before ordering.
