Huawei 03030HNK BTS3900 GSM Base Station Telecom System Card / Module

The Huawei 03030HNK is a GTMU (GSM Transmission, timing and Management Unit) main control and transmission board for Huawei’s BTS3900-series GSM base transceiver stations. Identified as the GM-GTMU variant supporting 4E1+2FE+6CPRI interfaces with CAN capability, it is the central control card of the base station, controlling and managing the entire BTS: handling equipment configuration, performance monitoring, radio-resource management and active/standby switchover, processing signalling, and providing the clock reference, transmission ports and OM channel to the local maintenance terminal or network management system. It also interconnects baseband processing boards, exchanging control, transmission and clock information across the BTS3900 chassis. This listing covers genuine Huawei stock removed from decommissioned GSM base stations, tested where possible prior to sale. Supplied by Tech-Star (UK-based, shipped worldwide); please enquire to confirm exact chassis/software-version compatibility before ordering.
