Anea 96 connectors, transmit a maximum of 21 E1/T1 signals. 21*E1 cables 120-ohm twisted pair cables. Apply for Huawei Huawei OSN500, OSN550, OSN1800 Multi-Service Transmission Platforms (MSTPs) for both TDM and packet network services, optimizing processing for IP-based communications and traditional SDH services under a uniform switching architecture. MSTP systems work in pure packet mode, pure TDM mode, and hybrid mode (packet + TDM), providing rigid and flexible channels, 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. Supports multi-service access, hard and soft pipes adopt ODUk for physical isolation 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 Smart 10 GE/40 GE line card software supports smooth expansion from 10 GE to 20 GE, 30 GE, and 40 GE, suitable for use in Smart “all 40 GE” large-bandwidth solutions Widely used by governments and enterprises, especially in the power, transportation, and TV broadcasting industries
