ATU-R

An ATU-R (ADSL Terminal Unit - Remote), sometimes called an "ADSL modem," is a hardware unit that is installed in any computer that uses a telephone company connection with Asymmetric Digital Subscriber Line (ADSL) service. The ATU-R connects to an Ethernet network interface card (NIC) in the computer and, on the other side, to a telephone jack in the home or business. Ideally (for less interference), the telephone jack hooks up to a new wire that goes to a signal splitter that the telephone company installs at the telephone company demarcation point (the place where the outside phone company wire or wires connect to the network of phone lines within the customer's building). The splitter divides the signal into low frequencies for voice and high frequencies for data.



ATU-C

(ADSL Transceiver Unit) A device that provides ADSL modulation of the telephone line. The device at the telco side is the ATU-C (Central), which is a line card plugged into the DSLAM. The unit at the customer's side is the ATU-R (Remote), which is either an external modem or a card plugged into the PC
