STM-1 ADM 16E1

The STM-1 ADM 16E1 is a medium-capacity SDH multiplexer ideal for utilities, metro transport networks, and industrial communication systems. It aggregates up to 16 E1 circuits and maps them into an STM-1 optical link, providing reliable long-haul communication with SNCP/MSP protection. The unit offers flexible service interfaces including E1, Ethernet, and data channels, enabling hybrid TDM + packet transport. With built-in alarms, loopback functions, and performance monitoring, it simplifies network maintenance and management.
