XRT7300 DS3/E3/STS-1 Line Interface Unit

The XRT7300 is a full featured Line Interface Unit (LIU). In the transmit direction, it accepts digital clock and data from the terminal equipment, usually a TDM framer (XRT7250), or an ATM UNI (XRT7234/XRT7245). It optionally encodes the data, and converts it into the appropriate pulse shapes for transmission over coaxial cable. In the receive direction, it accepts a bipolar signal from the line, optionally performs equalization, converts the line signal into a dual rail binary data stream, recovers the clock, optionally decodes the data, and coverts it into a dual rail digital signal.
