www.DataSheet4U.com CEPT/T1 In/Output Transformer Typical applications are: • • • TEW4980 TEW4980 is designed to be used either as a transmit or a receive transformer in the ISDN primary access network, interfacing SIEMENS PEB2235 and PEB2236 to a 75, 100 or 120 ohm line. When in transmit mode, connect the two primary windings in parallel, pin 1 to 3 and pin 2 to 4. When in receive mode, connect the two primary windings in series, pin 2 to pin 3, thus forming a center tap at pin 2/3. Primary rate ISDN network nodes. PBX or computer to T1/CEPT Digital trunks. TDM Multiplexers. Certified to EN60950 & EN41003 MECHANICAL 5 1 2 3 8 TEW4980-1, -2, & -3 4 Com 5 1 2 WHITE DOT AT PIN 1 AlLL DIMENSIONS ARE IN INCHES 75 Ω 7 120 Ω 8 TEW4980-4 3 4 TEW4980.
