4E1 PDH Optical Multiplexer with 1FE Ethernet EOW Phone Console NMS 120km Transmission

The 4E1 + 1FE + EOW + Console NMS represents a highly integrated access multiplexer designed for

compact network deployment scenarios. This versatile platform efficiently converges four standard E1

interfaces with one auto-negotiating 10/100M Fast Ethernet port and an optional Engineering Order

Wire (EOW) telephone channel, providing comprehensive service transport capabilities in a single

compact unit. The integrated console network management system enables direct local configuration

and real-time performance monitoring through both serial interface and web-based management options.

Engineered for maximum operational reliability, the system incorporates advanced alarm reporting

functionality that monitors critical parameters including signal loss, synchronization status, and power

conditions. The device's high-level integration and optimized power design result in exceptionally low

energy consumption while maintaining stable operation across extended temperature ranges. Its

compact physical dimensions make it particularly suitable for space-constrained installations in

remote cabinets, mobile base stations, and enterprise network access points.

This multiplexer delivers exceptional flexibility through its modular architecture, allowing network

operators to deploy it across diverse applications including cellular site backhaul, enterprise branch

connectivity, and emergency communication systems. The integrated EOW functionality provides

direct voice communication for field maintenance teams, while the comprehensive management

interfaces ensure efficient network oversight. With its robust construction and carrier-grade

components, this solution offers telecommunications providers and enterprise users a reliable,

cost-effective platform for hybrid service transport requiring minimal rack space and power resources

while delivering maximum operational efficiency and network visibility.
