Product Description & Overview
Featuring four fully switched Gigabit Ethernet interfaces with comprehensive VLAN support and traffic
management capabilities, this robust multiplexer enables sophisticated network segmentation and bandwidth
allocation. The dual expansion interfaces provide exceptional flexibility for RS232/RS485/RS422 asynchronous
data, voice channels, E&M audio signals, switch controls, and additional Ethernet connectivity with dedicated 2M
bandwidth allocation per channel. Advanced performance monitoring and fault detection systems deliver real-time
visibility into network operations across all service interfaces.
The compact design incorporates high-density integration and advanced power management technology, achieving
exceptional energy efficiency in a space-optimized footprint. With hot-swappable module support and extended
environmental tolerance, this solution is ideal for 5G mobile backhaul, enterprise network convergence, and mission
-critical industrial communications. Enhanced synchronization features and comprehensive alarm reporting guarantee
reliable operation in the most demanding network environments, establishing this PDH multiplexer as the premier
choice for modern multi-service transport applications requiring robust E1 and Gigabit Ethernet transmission over
protected fiber optic infrastructure.
