High Availability Multi-Service Aggregation

The M6424 is a TSN-based Ethernet Fronthaul Platform with RoE Mapper for 4G CPRI, 5G eCPRI and Ethernet Services. The M6424 is a hardened switch supporting 25Gbps and 100Gbps interfaces and time sensitive networking (TSN) for latency and timing-dependent 5G networks.

M6424 Datasheet

M6424 Overview

The M6424’s high performance design is purpose built for Time Sensitive Networks(TSN), enabling advanced mobile networking architectures and applications with nanosecond timing requirements.

Connect direct to cellular radios using Common Public Radio Interface(CPRI) and eCPRI, bridging the traditional mobile network and Ethernet infrastructure for a modern centralized or cloud-based NFV mobile architecture.

CPRI traffic is encapsulated using IEEE 1914.3-compliant Radio-over-Ethernet(RoE) mappers, integrated synchronization provides performance that exceeds existing solutions.

Flexible network deployment, supporting both controlled and hardened environments. Centralized fronthaul aggregation to BBUs and cloud topologies feeding TOR to vBBU. Hardened remote deployment enables service blending, CPRI aggregation at the remote radio head (RRH) with evolving RRH small cell eCPRI densification.
