The DS21Q348 design kit is an evaluation board for the DS21Q348 3.3V E1/T1/J1 line interface. The DS21Q348DK is intended to be used as a daughter card with either the DK2000 or the DK101 motherboards. The board comes complete with a line interface unit (LIU), transformers, termination resistors, configuration switches, network connectors, and an interface to the motherboard.
