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.

Universal Switch and Intelligent Transport

Unique architecture integrates PCM, TDM and MPLS-TP technology. Smart 40G line card enables carefree evolution among different types of services.
Highly Efficient and Available Universal Transport

Physical hard pipe features include strict physical isolation, low delay, low jitter, and high security. Soft pipe features include logical isolation, high transmission efficiency, and MPLS-TP ring protection.
40G Smart Line Card for Flexible Adustment

Integrates OTU, MUX, and DEMUX boards via a PID chip, providing 40G capacity per port with 50% footprint saving and 50% power consumption reduction.
