TEW-5315 Series Input/Output Transformer

TEW-5315 is designed to be used either as a transmit or a receive transformer in the ISDN primary access network, interfacing the SIEMENS PEB2235 to a 75, 100 or 120 ohm line. When in transmit mode, connect the two primary windings in parallel, pin 3 to 4 and pin 6 to 5. When in receive mode, connect the two primary windings in series, pin 6 to pin 4, thus forming a center tap at pin 6/4.
