Abstract:
A signal splitter, comprising:a circuit protection having a line side and a circuit side, the line side being coupled to a TIP line and a Ring line; a signal splitting low pass filter for splitting POTS signal transmission from digital data signal transmission, the signal splitting low pass filter having a single stage with two or more orders of filtering and having a first pair of leads and a second pair of leads, the first pair of leads being coupled to the circuit side of the circuit protection; a subscriber loop interface circuit having a third pair of leads, a transmit pair of leads and a receive pair of leads, the third pair of leads being connected to the second pair of leads of the signal splitting low pass filter; a low voltage filter having an input pair of leads and an output pair of leads, the input pair of leads being connected to the transmit pair of leads of the subscriber loop interface circuit, the low voltage filter having two or more orders of low pass filtering; and a coding/decoding circuit having a digital transmit lead, a digital receive lead, a pair of analog transmit leads, and a pair of analog receive leads, the pair of analog transmit leads being connected to the output of the low voltage filter and the pair of analog receive leads being connected to the receive pair of leads of the subscriber loop interface circuit.
