Technical content
TEW5315 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. Typical applications are:
- Primart rate ISDN network nodes.
- PBX or computer to T1/CEPT Digital trunk
- TDM Multiplexers Line Impedance (1-8) 100 Ω 75 Ω 120 Ω 120 Ω (1-7) 75 Ω Inductance (mH) (1-8) > 3.4 > 0.75 > 1.2 > 1.2 Pulse Mask T1 CEPT CEPT CEPT Return Loss T1.408 G.703 G.703 G.703 Dielectric Strength (Vrms) 1500 1500 1500 1500 Filtran Limited 229 Colonnade Road, Nepean, Ontario, Canada.
