Super Star LM63 is a standard SDH terminal multiplexer, and is a member of Skyway’s “Super Star” family. It multiplexes 63 E1 signals into a STM-1 stream, with TU-12 cross-connect capability. This compact multiplexer is housed in a standard 19” 1U rack mount box.
As a standard and compact SDH TM device, Super Star LM63 is best suited to applications where high-density E1 ports are required to interface with a SDH network through STM-1 fiber optic connections. For example, it is often used as a concise E1 port extension device for other “Super Star” family members, such as Super Star LMFIT, in various network topologies.
The device can be managed either through the embedded DCC channel within the STM-1 signal, or through the local RJ45 management interface on the equipment panel. When multiple Super Star LM63s are stacked together, a  RS485 bus may be used to link the units to form a single managed object. There are also alarm indication lights and a LCD screen available on the panel for operation monitoring.
