Universal Transport Platform

Huawei’s Universal Transport Platform works in pure packet mode, pure TDM mode, and hybrid mode (packet + TDM), providing rigid and flexible channels, and built-in PCM, supporting Smart 40 GE line cards for large-bandwidth applications. All models offer the flexibility to migrate to an all-IP network, and are based on a uniform architecture to simplify maintenance and reduce O&M costs.
