Product Description & Overview
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.
