FILTRAN TEW5315-3

CEPT/T1
TEW5315
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.
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.
Typical applications are:
When in transmit mode, connect
the two primary windings in
parallel, pin 3 to 4 and pin 6 to 5.
