CEPT/T1 TEW5736 Input/Output Transformer TEW5736 is designed to be used, either as a transmit or as a receive transformer in the ISDN primary rate access network, interfacing the Siemens PEB2235 and PEB2236 devices When in receive mode, connect the two primary windings in seriesp, pin 5 to pin 3. Complies with ANSI T1.408 and CCITT I.431, with regards to Longitudinal Balance and with T1.408 and G.703 for the return Loss. Typical applications are: When in transmit mode, connect the two primary windings in parallel, pin 2 to 3 and pin 5 to 4. • Primary rate ISDN network nodes. • PBX or computer to T1/CEPT Digital Trunks. • TDM Multiplexers.
