TEW5315
TEW5315 is CEPT/T1 In/Output Transformer manufactured by Filtran.
..
CEPT/T1
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.
In/Output Transformer
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 puter to T1/CEPT Digital trunk TDM Multiplexers
