5 DESCRIPTION OF THE DEVICE
5.1.1 Background
MDS92xxx-10BT is a device of Digital Subscriber Line (DSL) system used for data transmission
over symmetrical physical copper lines. The TC-PAM line encoding technology (G.shdsl
standard), which was accepted by ITU as the only world standard of high-speed symmetrical data
transmission over one pair, is used to transmit data over a twisted pair. The device consists of the
following:
• CPU with a firmware;
• memory unit;
• signal processor;
• power supply unit (DC/DC converter);
• Ethernet 10BaseT network interface;
• management interface;
• line interface.
