The bandwidths for telecontrol transmission are usually much lower than for today’s residential internet access. Therefore, SHDSL transmission technology, particularly with pair bonding, is often an interesting solution for some paths.
In addition to transmitting Ethernet IP data, interfaces like E1 (G.703) and V.24/V.28 (RS232) are still sometimes required. Combining or integrating these interfaces into the xDSL modems is therefore one solution. There are also other frequent requirements, such as a greater temperature range, so that industrial Ethernet devices can also be used.
