UTD-EM-M16 device is an Ethernet inverse multiplexer with 16 x E1 (G.703 2048kbit/s) interfaces. It allows connection of Ethernet network using one to sixteen E1 channels aggregating their band. Joining of E1 streams into a common transmission channel is based on inverse multiplexation with in-built mechanisms adapting differences in times of transferring packages in separate lines. By using 16 E1 channels, it is possible to obtain the maximum throughput of 32.768 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 and the transmission in the channel is restored.
CONCENTRATOR WORKING MODE:
UTD-EM-M16 can be also used to collect traffic from different LANs connected by nxE1 lines (n from 1 to 16). This is an efficient and economic solution to distribute Internet access over TDM network. UTD-EM-M16 working as a concentrator can distribute traffic according to VLAN IDs.
UTD-EM-M16 can be used as concentrator with FIBRAIN (UTD-EM-AE1, UTD-EM-M4, UTD-EM-M8, UTD-EM-T) and other vendor's devices (Eth./1xE1) .
