UTD-EM-T 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, where the main stream of packages is restored. 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 and the transmission in the channel is restored.

- Connects Fast Ethernet LANs over up to four E1 line (8192 kbit/s )
- Framed (G.704) and unframed E1 interfaces (selectable)
- Two working modes: Multiplexer, bridges two LANs over E1 channels; Concentrator, collects traffic from different LANs connected by 1-4 E1 channels
- Built-in four port Ethernet switch with an array of 1000 MAC addresses
- Automatic E1 channel failure detection, removal and addition of E1 channels, smooth adjustment of Ethernet bandwidth
- IEEE 802.1q support. Possibility of defining up to 15 VLAN networks (full range VID) in order to create independent transmission channels
- Two synchronization modes: internal or external clock
- Maintenance and Management: WWW, TELNET, SNMP, RS232 serial port
- Local and remote E1 loopbacks
