    Overview

    Huawei U181DTU02 Overview

    The Huawei U181DTU02 is a unified gateway digital trunk expansion module for U1900 Series enterprise voice systems. It accommodates up to 10,000 users and supports analog phones, IP phones, video phones, and soft clients in converged UC deployments across Asia, Europe, Africa, and North America. With 30 E1 ports or 20 T1 ports and trunk protocols such as SS7, R2, PRI, QSIG, and SIP, it helps distributors, SMB integrators, and end users smoothly integrate legacy TDM trunks into modern IP voice networks. Carrier-class reliability, flexible power options, and rich conferencing capabilities make it ideal for scalable enterprise communications.
