Huawei UG01MTNB0 256k TDM switching; 4x8k TDM cascading; 1+1 backup mode Telecom System Card / Module

The Huawei UG01MTNB0 (MTNB) is a TDM switching board used in the SSM256 service frame of the Huawei UMG8900 media gateway, a core-network platform used in GSM and UMTS networks to provide voice, multimedia and data media gateway services. The board provides 256k TDM switching capability, using 4x8k TDM cascading connections, and runs in 1+1 backup mode for high availability, so a fault on one MTNB board hands over to its partner without a service outage. It forms part of the UMG8900’s switching board tier, working alongside the MNET (GE switching) and MCLK (clock) boards in the same frame to keep TDM traffic routed correctly across the shelf. It is stocked as a like-for-like maintenance spare for operators keeping an existing UMG8900 deployment running rather than migrating to a newer media gateway platform. Tech-Star (UK-based, shipped worldwide) supplies this board tested and ready to deploy – get in touch to confirm stock and compatibility with your UMG8900 frame.
