DM810 Compact SDH Multiplexer

DM810 SDH Multiplexer STM1/4The DM810 is a compact new generation multiplexer with 1U high, compatible with standard 19-inch racks. It adds multi-service functionality to the access applications for transport networks. With a non-blocking cross connection matrix with 2.8G capacity, STM-1/4 interfaces, Gigabit Ethernet and E1, allows voice, video and data services implementation with reduced cost.

The DM810 platform is formed by several versions, each one containing different interface configurations, allowing the best solution to the desired application and cost optimization.
