UTD-EM-M4 device is an Ethernet inverse multiplexer with 4 x E1 (G.703 2048kbit/s) interfaces. It allows connection of Ethernet network using one to four E1 channels aggregating their band. Ethernet packages stream is divided into 4 E1 channels and then, in the second device, different E1 channels are multiplexed into one channel by using 4 E1 channels, it is possible to obtain the maximum throughput of 8.192 Mbit/s for Ethernet packages. The malfunction of a single E1 channel, regardless of a direction, causes its automatic switch off and no loss of packages. In case the line is back in operation, such a condition is automatically detected by the device.
